Nanostructured Bismuth-based materials are promising electrodes for highly efficient electrochemical reduction processes such as hydrogen evolution reaction (HER). In this work, a novel sort of nanocomposite made up of partially reduced Bi2O3 into metallic Bi anchored on a 3D network of Ni-foam as a high-performance catalyst for electrochemical hydrogen reduction. The application of the hybrid material for HER is shown. The high catalytic activity of the fabricated electrocatalyst arises from the co-operative effect of Bi/Bi2O3 and Ni-foam which provides a highly effective surface area combined with the highly porous structure of Ni-foam for efficient charge and mass transport. The advantages of the electrode for the electrochemical reduction processes such as high current density, low overpotential, and high stability of the electrode are revealed. An overall comparison of our as-prepared electrocatalyst with recently reported works on related work is done.

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.
