General Scheme for Oxidative Quenching of a Copper Bis‐Phenanthroline Photosensitizer for Light‐Driven Hydrogen Production
Authors: Windisch J. , Orazietti M. , Hamm P. , Alberto R. , Probst B. 
Published: May 2016

AbstractA new, general reaction scheme for photocatalytic hydrogen production is presented based on oxidative quenching of a homoleptic copper(I) bis‐1,10‐phenanthroline photosensitizer (PS) by 1‐methyl‐4‐phenyl‐pyridinium (MPP+) as the electron relay and subsequent regeneration of the so formed copper(II) complex by a sacrificial electron donor. Electron transfer from the relay to various cobalt based water reduction catalysts and subsequent H2 production was shown to close the catalytic cycle. Transient absorption experiments unambiguously confirmed the proposed pathway, both the oxidative quenching and subsequent regeneration of oxidized PS. Photocatalytic test runs further confirmed the role of MPP+ and up to 10 turnovers were achieved in the relay. The performance limiting factor of the system was shown to be the decomplexation of the copper PS. Quantum yields of the system were 0.03 for H2 production, but 0.6 for MPP. formation, clearly indicating that unproductive pathways still prevail.
Nature‐Inspired Design of Artificial Solar‐to‐Fuel Conversion Systems based on Copper Phosphate Microflowers
Authors: Wang Jing , Zhu Ting , Ho Ghim Wei 
Published: May 2016

AbstractPhosphates play significant roles in plant photosynthesis by mediating electron transportation and furnishing energy for CO2 reduction. Motivated by this, we demonstrate herein an artificial solar‐to‐fuel conversion system, involving versatile copper phosphate microflowers as template and titanium dioxide nanoparticles as host photocatalyst. The elaborate flowerlike architectures, coupled with a unique proton‐reduction cycle from interchangeability of different species of orthophosphate ions, not only offer a 2D nanosheet platform for an optimal heterostructure interface but also effectively augment charge‐carrier transfer, thereby contributing to enhanced photoactivity and hydrogen generation. These nature‐inspired, phosphate‐derived nanocomposites advance the synthesis of a large variety of functional materials, which holds great potential for photochemical, photoelectric and catalytic applications.
