# Raymond Gorte

Raymond John Gorte is an American chemical engineer, currently the Russel Pearce and Elizabeth Crimian Heuer Endowed Professor of Chemical and Biomolecular Engineering (CBE) and Materials Science & Engineering (MSE) at the University of Pennsylvania. Throughout his career at the University of Pennsylvania and the University of Minnesota, he has advanced the study of fuel cells and catalysts including heterogeneous metals and zeolite materials. He is a member of the U.S. National Academy of Engineering.

## Early life and education

Gorte was born in Wisconsin and grew up in Manitowoc, Wisconsin. In 1976, he earned a Bachelor of Science in chemical engineering from the University of Wisconsin-Madison. He completed his Ph.D. in chemical engineering at the University of Minnesota in 1981 with advisor Lanny D. Schmidt on the topic of platinum catalysis of nitric oxide decomposition. His thesis was published in 1981 with the title, "The Kinetic Interaction of Nitric-Oxide with Single Crystal Platinum".

## Professor of chemical engineering

Gorte joined the University of Pennsylvania's Department of Chemical and Biomolecular Engineering in Philadelphia in 1981. He was promoted to associate professor in 1987, and professor in 1993. He is a member of the Penn Center for Energy Innovation, the Laboratory for Research on the Structure of Matter (LRSM), and the Catalysis Center for Energy Innovation.

### Fuel cells

Gorte's research in solid oxide fuel cells addresses the design of electrodes and applications in hydrocarbon oxidation. In 2000 he published an article in Nature with John Vohs describing the oxidation of methane and higher hydrocarbons with a composite anode of copper and ceria that achieves viable power densities while producing carbon dioxide and water.

### Solid acids

The design, synthesis, and utilization of solid acids such as amorphous silica-alumina, ZSM-5, or synthetic faujasite relies on an understanding of the chemical site of acidity. Gorte has proposed a description of solid acidity based on a thermochemical cycle including the proton affinity, the interaction energy, and the enthalpy of adsorption. Gorte has also developed a method for quantifying acid site concentration based on alkylamine decomposition by the Hoffmann elimination reaction occurring by temperature programmed desorption (TPD). He has recently extended this to a highly precise method of "reactive gas chromatography".

### Catalytic chemistry

Gorte's research in catalyst design has led to research projects on numerous applications and chemistries. He has published papers on the water-gas-shift reaction catalyzed by supported metals such as ceria-supported Pt, Pd and Rh. Other applications include:
* CO oxidation on supported metals
* Steam reforming of alkanes such as methane and butane.
* Dehydration of alcohols.

Gorte has authored more than 400 journal articles on catalysis, surface chemistry, and fuels cells which includes:
