With the rapid increase of energy demand in people's daily life and the depletion of fossil
fuel reserves, research on new environment-friendly energy sources and their practical …

Platinum (Pt)-based materials are the first choice as the electrocatalyts for many
electrochemical reactions including those in fuel cells and electrolyzers due to their …

States of chemisorbed H that can be involved in the mechanism of the cathodic H2 evolution
reaction (HER) at metals, specially Pt, and the reverse oxidation reaction (HOR), are …

CO poisoning of Pt-group metal catalysts is a long-standing problem, particularly for
hydrogen oxidation reaction in proton exchange membrane fuel cells. Here, we report a …

Fuel cells, especially low temperature fuel cells are clean energy devices that are expected
to help address the energy and environmental problems that have become prevalent in our …

Biomass and its derivatives provide renewable alternatives to fossil-fuel resources for the
sustainable production of liquid fuels and valuable chemicals.[1] The challenge for the …

▪ Abstract After a brief survey of fuel cell types, attention is focused on material requirements
for SOFC and PEMFC stacks, with an introductory section on materials technology for …

Platinum group metals (PGMs) serve as highly active catalysts in a variety of heterogeneous
chemical processes. Unfortunately, their high activity is accompanied by a high affinity for …

Platinum reaches considerable activity and stability as an electrocatalyst but is not always
capable of maintaining such performance under CO poisoning, particularly in CO residual …

γ-Al2O3, ZrO2, and TiO2 gold supported model catalysts have been synthesized by laser
