Computational Modeling for CO2 Electrochemical Reduction on Cu-based
Materials
Ming-Kang (Brad) Tsaiaa. Department of Chemistry, College of Science, National Taiwan Normal University,
Taipei 11677, Taiwan
Electrochemical reduction of CO2 into liquid fuel is an ultimate-and-ideal cycle for realizing thecatalytic application of the renewable energy storage. With preparing the Cu catalyst from thereduction of copper oxide, as known as OD-Cu, Li et al. observed a wide range of single- andmultiple-carbon hydrocarbon products from CO reduction reaction (CORR), in order to preclude
the complex reduced-intermediate absorption kinetics on Cu surfaces [Nature 2014]. Toward the
purpose of understanding the rate-determining step of C‒C bond formation, Nørskov andco-workers calculated CO••CO dimerization barrier on several Cu surfaces with the presence of a
proton and explicit water molecules, and the barrier was predicted to be experimentally accessiblearound 0.5 eV [Surface Science 2016].
In this talk, our computational efforts in understanding the important factors to enhance theC‒C bond coupling process will be reported, e.g. solvation, mixed-valence surface and surface
stains. The corresponding experimental observations related to the aforementioned factors will bealso discussed. In addition to the CO2 electrochemical reduction reactivity predicted by the selectedslab models, the integration of modelling methodology combining Density Functional Theory(DFT), molecular mechanics (MM), and electric filed will also be also be demonstrated.

Development of Function-Integrated Catalytic System for Small Molecule
Conversion
Mio Kondo
Division of Applied Chemistry, Graduate School of Engineering, Osaka University, Suita, Osaka
565-0871, Japan
Development of catalysts for small molecule conversion reactions has drawn tremendous attention
recently because of the urgent need to solve the world’s energy and environmental problems. In
particular, the catalysts that can produce sustainable fuels and chemicals from abundant sources arehighly required. In this study, we aimed to develop novel catalytic systems for molecule conversion
reactions based on function integration into metal complexes. The following two topics will bepresented in the talk.
1. Function-Integrated Catalyst for Water Oxidation
The water oxidation reaction (2H2O→ O2 + 4H+ + 4e−) is an essential
reaction to provide the protons andelectrons requisite to generatechemical fuels. We assumed that
efficient water oxidation catalyst canbe constructed by integrating
following two key features; (i)multinuclear structures to promote
multi-electron transfer and (ii) two
adjacent water-activation sites to Figure 1. Strategy to design a function -integrated catalyst for

formation (Figure 1). Based on thestrategy, we employed a pentanuclear iron complex with adjacent open-coordination sites.
Electrochemical analysis revealed that the pentairon complex can serve as a higly active wateroxidation catalyst with the turnover frequency of 1,900 s−1.
2. Function-Integrated Catalyst for Photocatalytic Hydrogen Evolution
In this study, we aimed to develop
novel
molecular-based
catalytic
systems, in which the advantageous
features of homogeneous andheterogeneous systems are integrated.
In our system, a discrete catalyst

a heterogeneous framework catalyst (Figure 2). A Rh(II) dimer complex-based catalyst module was
self-assembled by simple recrystallization to afford a framework catalyst. The photocatalytic studiesof the framework catalyst that the framework can promote photocatalytic H2 evolution with the longlived activity and was reused without considerable loss of catalytic activity.

ABSTRACTElectrochemical reduction of CO2 is heavily pursued as a potential solution of CO2 recycling
and realizes the high-density renewable energy storage. Among numerous types of catalysts,
copper-based catalysts have been shown to perform interesting nature toward hydrocarbon
products. Nevertheless, achieving practical CO2RR selectivity toward desired products on thestate-of-the-art copper-based catalysts is still facing great challenges. The great challenge forpromoting the CO2RR selectivity may arise to a fact that this electrochemical process is amultiple proton-electron-transfer step and highly surface-sensitive, implying that the surface
state of electrocatalyst may be dynamic and unpredictable under practical situations. By
employing the comprehensive in-situ techniques we developed during past few years, wehave demonstrated the first empirical demonstration to track the dynamic structural
reconstruction/transformation in a model bimetallic system, which establishes a goodunderstanding of the correlation between catalyst surface structure and catalytic selectivity.
Furthermore, we also realized a very important achievement to develop an operando secondsresolved X-ray absorption spectroscopy to uncover the chemical state evolution of working
catalysts. It’s well-known that a chemical reaction driven by applied potential is extremely
fast, which is difficult to track the electrochemistry with acceptable temporal-resolution. This
work is able to offer scientific insights into the roles metal states serve in chemical reaction inelectrolyte.

Plasmonic p–n Junction for Infrared Light to Chemical Energy
Conversion(1Institute for Chemical Research, Kyoto University) ○Masanori Sakamoto1

evolution
The parts of the solar spectrum used for solar energy conversion, including
photosynthesis and artificial photosynthesis, are limited to the ultraviolet (UV), visible, anda limited region of near infrared (NIR) light (700–1000 nm). IR light, which accounts foralmost half of all solar energy, particularly IR light at wavelengths longer than 1000 nm,
including shortwave IR (SWIR: 1400–3000 nm), represents a vast source of untappedenergy. Developing artificial IR light-to-energy conversion systems would open up thisresource for applications.
Here, we synthesized an IR-responsive plasmonic energy conversion system composedof CdS/plasmonic Cu7S4 heterostructured nanocrystals (HNCs), which achieved highly
efficient photocatalytic H2 evolution (Figure 1a). Cu7S4 NCs, which exhibit localized
surface plasmon resonance (LSPR) in IR region, can be applied to harvesting solar energy
in the IR region (Figure 1b). The CdS/Cu7S4 HNCs exhibited an exceedingly high apparent
quantum yield (AQY) of 3.8% at 1100 nm, which exceeds the current record forphotocatalytic H2 evolution under IR-light irradiation (Figure 1c). Furthermore, we
demonstrated that our novel HNCs can convert energy from the solar spectrum up to thelongest wavelengths (i.e., 2000–2500 nm). Our spectroscopic investigations using
femtosecond-laser flash photolysis revealed that the high catalytic activity of our system
was related to efficient hot electron injection and long-lived charge separation (> 273 μs) at
the p–n heterojunction of the CdS/Cu7S4 HNCs. The present work should encourage further
development of solar fuel generation systems driven by these previously untapped solar
energy resources.

Building bimetallic surfaces on nanocrystals renders them superior catalysts for energy-conversion
reactions by virtue of the electronic effect. In addition, integration of plasmonics and catalysis inbimetallic nanocrystals provides more benefits for the creation of novel catalyst systems. In this talk,selected stories about utilization of CuM bimetallic nanocatalysts for catalytic and photocatalytic
energy-conversion reactions will be introduced.[1] All stories start by the synthesis of Cu nanocubes
which serve as the templates for further surface engineering. On the Cu nanocubes, we reduce various
kinds of noble metallic ions to form CuM surfaces with precise-controlled thickness less than 2 nm
(7-8 atomic layers). In typical, template-based syntheses exhibit the coating shells with a consistentmorphology to their mother nanotemplates via epitaxial growth. However, our atom-level surface
modulation on the surfaces of Cu nanocubes exhibit unconventional morphological transformation
after formation of CuM shells. Moreover, treating Cu-CuM core-shell nanocrystals with acid toremove Cu cores triggers further morphological transformation, leading to final nanocages in a
specific shape. Those nanocages are eventually applied to electrocatalysis (oxygen reduction reaction,
ORR) and photocatalytic synthetic reaction (4-nitrophenol reduction reaction). It turns out that thesenanocages possess at least triply high mass activities than that of commercial catalysts. Apart fromsurface-coated shells, fabrication of CuM nanoframes on the Cu nanocubes via selective depositionof metallic ions will be also introduced. These nanoframes have 3D-open skeletons with highly
exposed surface area and, more importantly, surface defects (i.e. adatoms and terraces).[2] The
characteristics make CuM nanoframes excellent catalysts in both electro- and photocatalysis. Below
shows the CuPt alloy nanocages and nanoframes synthesized from Cu nanocubes.
