“…In addition, the Mo 4+ 3 d 3/2 and Mo 4+ 3 d 5/2 of PMF catalysts correspond to the characteristic peaks located at 228.9 and 232.6 eV, respectively, while PMF catalysts Mo 6+ 3 d 3/2 and Mo 6+ 3 d 5/2 correspond to the characteristic peaks located at 233.6 and 235.5 eV, respectively. [ 29,30 ] In the Mo 3 d spectra of PMF/G‐25, the characteristic peaks of the PMF/G‐25 catalyst were shifted to higher binding energies compared to PMF.…”

In order to explore the application of graphdiyne in photocatalytic splitting of water and hydrogen evolution. In this paper, graphdiyne was prepared by ball milling using calcium carbide as raw material, and it was compounded with phosphating Mo‐MOFs, to explore the photocatalytic hydrogen evolution performance and hydrogen evolution mechanism of composite catalysts. The results showed that the PMF/G‐25 composite photocatalyst had the best hydrogen evolution activity, and the hydrogen production rate was highest at pH = 9, reaching 1668.5 µmol·g‐1·h‐1. Through the four‐cycle hydrogen evolution cycle stability test, the PMF/G‐25 composites still had good hydrogen evolution stability. The results showed that the combination of phosphating Mo‐MOFs and graphdiyne could enhance the hydrogen evolution activity and had excellent hydrogen evolution performance. The photoelectrochemical and fluorescence test results showed that the addition of graphdiyne could effectively improve the charge separation efficiency of the composite catalyst PMF/G‐25. The Mott‐Schottky test found that PMF and GDY were n‐type semiconductors, and their band structures were analyzed. The conduction and valence values were ‐0.56 eV and 1.10 eV for GDY, and ‐0.68 eV and 0.97 eV for PMF, respectively. The mechanism of photocatalytic hydrogen evolution was analyzed, and it was speculated that S‐Scheme heterojunction was formed between PMF and GDY to further promote photocatalytic hydrogen evolution.This article is protected by copyright.

Ammonia (NH 3 ) is a significant chemical and carbon-free energy carrier with important applications in industry and agriculture. Ammonia is primarily produced through the Haber−Bosch process (HB), which necessitates high temperatures and pressures, consumes a significant amount of energy, and produces a substantial amount of CO 2 . Electrocatalytic nitrogen reduction (NRR) for ammonia synthesis is a promising alternative to the HB process due to its mild reaction conditions and low energy consumption. However, the low ammonia yields reported for nonmetallic or metallic NRR catalysts are still far from the industrialization needs. In recent years, researchers have discovered that metal phosphides possess easy-to-regulate morphology, good stability, and synergistic properties that enable them to exhibit good electrocatalytic activity for the nitrogen reduction reaction. This emerging research direction has been identified as a promising approach for the development of high-performance NRR electrocatalysts. This article provides an overview of the advancements in the use of metal phosphides for electrocatalytic nitrogen reduction and ammonia synthesis in recent years. It briefly discusses their synthesis methods, structural modulation, and morphology modifications as well as the reaction mechanism and performance in nitrogen reduction reactions. Additionally, it addresses the potential challenges that metal phosphides may encounter in NRR applications and offers insights into future development prospects. This paper aims to propose innovative ideas for designing metal phosphide electrocatalysts to enhance the efficiency of electrocatalytic nitrogen reduction to produce ammonia.
