Selectivity reversal of photocatalytic CO2 reduction by Pt loading†
Abstract
In photocatalysis systems, precious metal co-catalysts play very important roles. Here, a photodeposition method is used to load Pt on different photocatalysts for photocatalytic CO2 conversion testing. The performance results indicate that the selectivity of semiconductor photocatalysts for CO2 reduction was effectively reversed from CO to CH4 due to the introduction of Pt.
