Supercritical synthesis of platinum-modified titanium dioxide for solar fuel production from carbon dioxide

The catalytic properties of Pt/TiO2 particles can be tuned by simply changing operating parameters like the type of titania precursor and/or hydrolysis agent when their hydrothermal formation reaction is accomplished in supercritical CO2. The synthesised particles exhibit superior performance to that of a commercial catalyst in the photocatalytic reduction of CO2 to methane.
