英文摘要	Fossil fuel combustion and automobile exhaust emissions are the main causes of the greenhouse effect. An effective measure to solve this problem is to convert carbon dioxide into green and clean energy. Photocatalytic technology is a green technology with important application prospects in the energy and environmental fields. At present, the catalyst has some defects, such as specific surface area is lower, the photoelectric-hole pair recombination rate is fast and the quantum efficiency is low. Therefore, effective photocatalysts have become the focus of researchers. In the paper, WSe2 was successfully prepared by the hydrothermal reaction using two different reductants and solvents, and the XRD, UV-Vis DRS, N2 adsorption-desorption tests are adopted for characterization of prepared sample. The XRD, UV-Vis DRS and BET characterization results show that the WSe2 samples prepared with two reductants both contain pure-phase WSe2, and the location distribution of main diffraction peaks is consistent with that of hexagonal WSe2 (JCPDS card, PDF#38-1388); the prepared WSe2 presents photo response within the range of 200-700nm, but compared with WSe2 (NaBH4), the light absorption intensity of WSe2 (N2H4.H2O) is significantly enhanced; compared with WSe2 (NaBH4), the specific surface area of WSe2 (N2H4.H2O) is bigger, which are 3.4 m2.g-1 and 3.0 m2 g-1, respectively. After photocatalytic reaction for 12h with the catalyst of two different WSe2 (N2H4.H2O) and WSe2 (NaBH4), WSe2 (N2H4.H2O) shows great photocatalytic activity, and the overall yields of CH3OH are 327.13 μmol g-1cat and 46.32 μmol g-1cat, respectively. © Published under licence by IOP Publishing Ltd.
