Nanocatalysts for the water–gas shift reaction

Abstract

The increasing degree of control over the nanostructure of materials through novel and refined synthesis pathways is enabling the development of catalysts with improved performance and, at the same time, allows new insights into the catalytic chemistry on a molecular level, thus paving the way to rational catalyst design strategies. This review focuses on recent developments in nanocatalysts for water–gas shift (WGS), a key reaction in current and emerging fuel-processing technologies. We review recent insights into catalytic reaction mechanisms and the development of nanostructured catalytic materials and highlight current gaps and challenges in the state-of-the-art of WGS nanocatalysts.
