A novel photocatalyst LaOF: Facile fabrication and photocatalytic hydrogen production

LaOF samples were synthesized by a facile hydrothermal method followed by a subsequent heat treatment. Its performance for photocatalytic hydrogen production under UV light irradiation was first reported. Loading of the Pt cocatalyst over LaOF was observed to efficiently enhance the photocatalytic H2 production activity. With techniques such as XPS, DRS, flat potential measurement and PL, the physicochemical properties of the LaOF samples were discussed.
