Design of cocatalyst loading position for photocatalytic water splitting into hydrogen in electrolyte solutions

148The new designed catalyst with Pt loaded on FTO (TiO2-Pt/FTO, red column) shows 2.4 times higher activity for photocatalytic hydrogen production than the common catalyst with Pt loaded on TiO2 (Pt/TiO2-FTO, black column) in acidic electrolyte.
