Melamine Foam

Carbonized melamine foam (CM) was used as an ideal framework for the in-situ growth of MoS2 by hydrothermal method. And its hydrogen evolution reaction (HER) and the catalytic mechanism were explored. By regulating the concentration of the precursor, the stacking pattern of MoS2 lamella on CM was optimized. And the results show that the sample with a precursor concentration of [Formula: see text][Formula: see text]M possesses the smallest overpotential (218[Formula: see text]mV @ 10[Formula: see text]mA[Formula: see text]cm[Formula: see text]) and its vertical arrayed nanosheets encased on the surface of carbon matrix provide more sites for the absorption of H[Formula: see text] in the electrolyte which accounts for the promotion of hydrogen generation.
