Highly mesoporous CsTaWO6 via hard-templating for photocatalytic hydrogen production

The quaternary photocatalyst CsTaWO6 was for the first time prepared with a high surface area of 115 m2 g−1 via a hard-templating approach. The highly crystalline and phase-pure material was applied in photocatalytic hydrogen production experiments to demonstrate the influence of porosity, surface area and crystallinity on charge carrier transfer.
