Research on the synthesis of nano nickel phosphide

Abstract Transition metal phosphides are a class of compounds with special structures that have garnered significant attention and applications in various fields, including optics, magnetism, catalysis, and ceramic materials. Nickel phosphide, in particular, exhibits distinctive characteristics in electronics, optics, and semiconductors, making it an important member of the transition metal phosphide family. It demonstrates excellent corrosion resistance, oxidation resistance, wear resistance, and waterproof properties, rendering it suitable for use as electrode materials in lithium-ion batteries and as catalytic materials. Notably, it has considerable applications as an additive in hydrogen desulfurization and denitrification catalysts, which have become prominent research hotspots. In recent years, nickel phosphide has been utilized in photocatalysis, gradually revealing its unique physical and chemical properties in the field of chemistry. However, the low separation efficiency of photogenerated electron-hole pairs has affected its performance in photocatalytic applications. Therefore, nickel phosphide is composite with other materials to improve its separation efficiency and enhance its surface adsorption performance. In this article, we utilize the induction effect of hydroxyl groups in ammonia water on metal ions to regulate the crystal structure of the catalyst.
