Advanced approaches to preparing non-noble-metal electrocatalysts for the hydrogen evolution reaction (HER) are considered to be a significant breakthrough in promoting the exploration of renewable resources. In this work, a hybrid material of MoS2 nanoflowers (NFs) on reduced graphene oxide (rGO) was synthesized as a HER catalyst via an environmentally friendly, efficient approach that is also suitable for mass production. Small-sized MoS2 NFs with a diameter of ca. 190 nm and an abundance of exposed edges were prepared by a hydrothermal method and were subsequently supported on rGO by microwave-assisted synthesis. The results show that MoS2 NFs were distributed uniformly on the remarkably reduced GO and preserved the outstanding original structural features perfectly. Electrochemical tests show that the as-prepared hybrid material exhibited excellent HER activity, with a small Tafel slope of 80 mV/decade and a low overpotential of 170 mV.

Highly efficient and stable non‐noble metal electrocatalysts for hydrogen generation are desired for sustainable development of energy conversion and storage. Here, a facile low‐temperature phosphidation process is developed for phosphorus doping into molybdenum disulfide (MoS2) nanosheets directly synthesized on carbon cloths to function as an integrated electrode for efficient hydrogen evolution reaction. The optimal phosphorus‐doped (3.3 at%) MoS2 nanosheets exhibit substantially lower overpotentials of 133 and 189 mV to drive the current densities of 20 and 100 mA cm‐2, respectively, as compared with undoped MoS2, and an impressively small Tafel slope of 67.0 mV dec−1. The excellent stability in acid media also makes the phosphorus‐doped MoS2 nanosheet catalysts promising candidates for hydrogen generation in practical applications.

Here, RGO, as the significant component of the specific structure of the composite electrocatalyst was further researched . As shown in Figure b, different weight content of RGO ranging from 3:1 to 20:1 was was mixed in the compound materials (the weight content was relative to the initial mass content 0.25 g of chitosan).…”

A highly efficient and pH-universal hydrogen evolution reaction (HER) electrocatalyst with a sandwich-architecture constructed using zero-dimensional N- and P-dual-doped core-shell Co P@C nanoparticles embedded into a 3 D porous carbon sandwich (Co P@N,P-C/CG) was synthesized through a facile two-step hydrothermal carbonization and pyrolysis method. The interfacial electron transfer rate and the number of active sites increased owing to the synergistic effect between the N,P-dual-doped Co P@C core-shell and sandwich-nanostructured substrates. The presence of a high surface area and large pore sizes improved the mass-transfer dynamics. This nanohybrid showed remarkable electrocatalytic activity toward the HER in a wide pH range with good stability. The computational study and experiments revealed that the carbon atoms close to the N and P dopants on the shell of Co P@N,P-C were effective active sites for HER catalysis and that both Co P and the N,P dopants gave rise to an optimized binding free energy of H on the active sites.
