Electrochemical water splitting is a possible way of realizing sustainable and clean hydrogen production but challenging, because highly active durable electrocatalyst essential. In this work, we integrated heterogeneous engineering vacancy defect strategies to design fabricate heterostructure (CoPv-MoxPv/CNT) with abundant phosphorus vacancies attached carbon nanotubes (CNTs). The defects enabled the optimization electronic structure; thereby, electron-rich low-valent metal sites enhanced ability nonmetallic P capture proton H. Meanwhile, interface between bimetallic phosphides CNTs realized rapid electron transfer. addition, Co, Mo, species in electrocatalytic process exposed increased amounts featuring porous nanosheet structures, which facilitated adsorption reaction intermediates thus evolution performance. particular, optimized CoPv-MoxPv/CNT catalyst possesses an overpotential 138 mV at current density 10 mA cm–2 long-term stability for 24 h. This work offers insights possibilities exploration transition metal-based electrocatalysts through combining multiple synergistic strategies.

Abstract Ta‐based transition metal catalysts have shown significant catalytic activity for the hydrogen evolution reaction (HER) in recent studies. However, application of tantalum phosphide (TaP) HER has not been documented. Herein, a systematic study TaP was performed through density functional theory (DFT). The performance (004) predicted. Thermodynamic analyses Ta‐terminated and P‐terminated surfaces with adsorbed atoms were conducted, mechanism on carefully investigated. Theoretical results revealed that exhibits excellent (ΔG H* =0.0456 eV), both follow Volmer‐Heyrovsky under acidic conditions, Volmer step being rate‐determining step. A mixed surface strategy also applied to explore synergistic effects surfaces, which enhanced activity. Additionally, screened dopants assess their impact activity, revealing doping S, Ni, Co, Fe, Cr could improve performance.

Hydrogen is an ideal alternative energy sources as it non-polluting and clean. The main commercial materials used for hydrogen production from electrolytic water are precious metals. Their high price has a negative impact on the industrialisation of water, there urgent need to research highly active durable non-precious metal replace them. Inorganic transition metals interest due their content low price. Here, we prepared performance stable Fe-CoMoO

Exploiting low-cost electrocatalysts with highly efficient and stable catalytic activity in both acidic alkaline solutions is the key to large-scale application of hydrogen production by water electrolysis. Here, Ru nanoparticle-anchored MoP@Mo composites were synthesized high-temperature phosphorization combined photodeposition method. Ru/MoP@Mo as an electrocatalyst for evolution reaction exhibited a Pt-like electrocatalytic activity, including low overpotentials 54 52 mV at 10 mA·cm–2 current density 0.5 M H2SO4 1.0 KOH solutions, respectively, small Tafel slopes, long-term stability mA·cm–2. Meanwhile, theoretical calculations revealed that excellent was ascribed strong electronic interaction between MoP, which optimizes adsorption tension H on surface thereby accelerates desorption H. This work provides new strategy preparing Mo-based HER high environments.
