Water gas shift is an industrially important reaction included in the process chain for producing pure hydrogen from methane or other hydrocarbon feedstocks. The relevance of the process has increased with the invention of modern fuel cells, which require high-purity hydrogen for power. The need to develop hydrogen infrastructure and, at the same time, the difficulties of transporting this gas have stimulated the search for catalysts that are convenient and effective for hydrogen production and purification in compact mobile units. For water gas shift reaction, noble metal catalysts are considered as possible options. This article presents a review of studies devoted to platinum catalysts supported on ceria and its doped forms for the water gas shift reaction. The influence of the oxide support composition on the catalytic properties of such systems is considered, variants of the reaction mechanism and active site structure are presented, and the results of studies of bimetallic Pt-containing and structured catalysts are summarized.
