Insights into the role of MgAl layered double oxides interlayer in Pt/TiO2 toward photocatalytic CO2 reduction

The representative TiO2 loaded with cocatalyst (e.g., Pt) have been used extensively for the photocatalytic CO2 reduction in solar-to-chemical energy conversion. However, it still suffers from low efficiency, due to the weak adsorption/activation of CO2. In this work, an MgAl layered double oxides (MgAl-LDO) was successfully introduced into the interface of Pt/TiO2, by in-situ deposition of MgAl layered double hydroxides and subsequent high...
