Multiple-interface relay catalysis: Enhancing alkaline hydrogen evolution through a combination of Volmer promoter and electrical-behavior regulation

Hydrogen Generation and Degradation of Organic Dyes by New Piezocatalytic 0.7BiFeO3–0.3BaTiO3 Nanoparticles with Proper Band Alignment

“…Usually hydrogen can be fabricated from direct waster splitting through the application of solar and electrical energy. Although sunlight-driven semiconductor photocatalysts have received broad attention for their ability to generate hydrogen under light irradiation, the high cost of the reaction, the low efficiency of solar energy utilization, together with the instability of the lack of response in the dark have restricted their practical applications. , In addition, the generation of hydrogen through direct water electrolysis has been another research hot spot in recent years. − However, the large consumption of electricity is an evident disadvantage of electrolysis. , Therefore, the demand for direct water splitting to yield hydrogen energy based on new mechanisms with low cost and high efficiency is increasing rapidly . Furthermore, due to the increasingly serious environmental pollution, it is also of great significance to develop versatile catalysts that can be used for dye wastewater treatment.…”

Interfacial engineering of metal–organic framework derived hierarchical CoP–Ni5P4 nanosheet arrays for overall water splitting

“…Such nanosheets may be oxidized to form metal oxides or peroxides on the CoP–Ni 5 P 4 surface. 51 As demonstrated by the XPS characterization (Fig. 5), a significant shift towards lower binding energies was observed in the principal peaks of Co 2p, Ni 2p and P 2p, indicating that the metal was oxidized to a higher valence state during the reaction.…”

“…Moreover, the use of an insulating polymer binder can block the exposure of the active site and the transportation of electrons to the NF electrode. 51 To investigate HER kinetic energy, the Tafel plots are shown in Fig. 3b.…”

Bismuth–nickel bimetal nanosheets with a porous structure for efficient hydrogen production in neutral and alkaline media

“…The formation of the pores may be attributed to the Kirkendall effect, where the pores are produced due to the different diffusion rates of Bi and Ni atoms during the electrochemical reduction process. 38…”
