Construction of heterogeneous 1T/2H MoSe2 homojunction nanosheets with excellent broad-spectrum photocatalytic activity
Source abstract
Abstract
Broad-spectrum heterogeneous 1 T/2H MoSe2 homojunction nanosheets were prepared using single-step solvothermal process. The 1 T and 2H phase ratios in the homojunction could be controlled by adjusting the amount of NaBH4. Moreover, the presence of 1 T phase in the 1 T/2H MoSe2 increased the absorption ability of MoSe2 and accelerated electron transport, which greatly enhances the photocatalytic degradation activity under broad-spectrum range. Radical trapping experiments indicated that ·OH and ·O2− radicals are the main active species of methylene blue degradation. Combined with the results of photocatalytic activity and band structure, the photocatalytic mechanism of the 1 T/2H MoSe2 was proposed.
