SYNTHESIS OF NANOCRYSTALLINE MOLYBDENUM DISELENIDE FOR ELECTROCATALYSIS OF THE HYDROGEN- EVOLUTION REATION
Abstract
Synthesis of MoSe2 nanocrystallinefrom Mo(CO)6 and Se by solvothermal method at 200oC, stored in 10h. The thickness of MoSe2 nanosheets with d(002) = 0.63 nm.
Investigation of the electrochemical catalytic activity of the material for the reduction of the proton to hydrogen by electrochemical methods, the results are very promising: the hydrogen generation process when the catalytic densities of -10mA/cm2 about 300mV. The results of the study also show that the ability to improve the catalytic activity of the MoSe2 is likely to be an expensive substitute for catalysis in photoelectrochemical cell.
