HNbxTa1-xWO6 monolayer nanosheets solid solutions: Tunable energy band structures and highly enhanced photocatalytic performances for hydrogen evolution
HNbxTa1-xWO6 nanosheets with the thicknesses of 1.50–2.00 nm were prepared. The band energy of monolayer nanosheet can be tunable via solid-solution strategy. The photocatalytic H2 generations were found dependent on their compositions. Solid-solution strategy is a useful method for developing efficient photocatalysts.
