The resulting powders were tested for the photocatalytic H2 generation. The photocatalyst (20 mg) was put into a photoreactor. 15 mL of water and 5 mL of methanol (which plays a role of a hole scavenger) were added to form a heterogeneous mixture. The prepared suspensions were degassed for 20 min under an Ar atmosphere with a continuous stirring. Subsequently, they were irradiated using 300 W xenon lamp. The amount of H2 produced in time from the water-methanol solution was measured using a gas chromatography (GC) with an INFICON Micro GC Fusion Gas Analyzer.
