John W. Weidner
Professor and Associate Chair
Editor, Electrochemical Society Transactions
Professor Weidner’s research group is involved in the
synthesis and characterization of electrochemically active
materials, and the design and operation of electrochemical
processes. The have created novel synthesis routines, used a
variety of electrocanalytical techniques, and developed
sophisticated mathematical models to advance the fields of
advanced batteries, electrochemical capacitors, fuel cells,
electrochemical synthesis in room temperature ionic liquids,
and electrolysis involving gas-fed anodes (e.g., HBr, HCl,
SO2) Their current research projects related to
hydrogen and alternative energy. They are: (1) developing nanostructured TiO2 supports for a solar-hydrogen system
that integrates III-V semiconductors, Fresnel lens
concentrators, and water electrolysis into a single unit; (2) synthesizing novel bi- and tri-metallic electrocatalysts
for proton-exchange membrane (PEM) fuel cells and direct
methanol fuel cells (DMFC); and (3) designing electrolyzers
and developing electrocatalysts for use in thermochemical
cycles for large scale hydrogen production from solar and
nuclear energy.
