Pt/CePO4 catalysts for the WGS reaction: influence of the water-supplier role of the support on the catalytic performance
(Royal Society of Chemistry, 2018)
For Pt catalysts which have demonstrated great activity for the WGS reaction, the activation of water is described as the rate-limiting step. Such limitation could be overcome through the design of supports able to supply ...
