Transition metal tetrametaphosphates (M2P4O12) are a novel electrode material for lithium-ion batteries (LIBs) due to their good electrical conductivity and reversible redox behavior. In this work, carbon layer self-encapsulated Ni2P4O12 nanoparticles were prepared by facile oil bath evaporation and high temperature calcination. A detailed investigation of the synthesis mechanism was performed through controlled variables. Among the various synthesis factors, the glucose introduction generates a self-coated carbon layer; the calcination temperature can directly affect the crystalline phase formation; the product was calcined at 800° equipped with the optimal lithium storage performance; the selection of organic phytic acid was correlated with the Ni2P4O12 micromorphology; and the dosage of phytic acid, while having an insignificant effect on the crystalline phase, strongly associated with lithium-ion storage. 4 mL of the phytic acid-synthesized Ni2P4O12 material showed the best lithium storage performance. On this basis, the fabricated NPO-PA-GL electrode materials were applied in LIBs, and electrochemical tests were conducted. Benefiting from the modulated electronic structure of the carbon layer, high specific surface area, and nanoparticle structure, the NPO-PA-GL electrode exhibited high-efficiency electrochemical activity. Particularly, the cell capacity amounted to 871.8 mA h g–1 at a current density of 50 mA g–1. After 500 constant-current charge/discharge cycles at 1 A g–1, the capacity increased by 128.4%. This work not only indicated that NPO-PA-GL would be a prospective LIB anode material but also pointed out a new direction for the exploitation of LIB anode materials, which will lead to significant innovations in sustainable chemistry and engineering.

Electrolysis is a trend in producing hydrogen as a fuel for renewable energy development, and urea electrolysis is considered as one of the advanced electrolysis processes, where efficient materials still need to be explored. Notably, urea electrolysis came into existence to counter‐part the electrode reactions in water electrolysis, which has hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Among those reactions, OER is sluggish and limits water splitting. Hence, urea electrolysis emerged with urea oxidation reaction (UOR) and HER as their reactions to tackle the water electrolysis. Among the explored materials, noble‐metal catalysts are efficient, but their cost and scarcity limit the scaling‐up of the Urea electrolysis. Hence, current challenges must be addressed and novel efficient electrocatalysts are to be implemented to commercialize urea electrolysis technology. Phosphides, as an efficient UOR electrocatalyst, have gained huge attention due to their exceptional lattice structure geometry. The phosphide group benefits the water molecule adsorption, and water dissociation and facilitates the oxyhydrate of the metal site. This review provides a summary of recent trends in phosphide‐based electrocatalysts for urea electrolysis, discusses synthesis strategies, and crystal structure relationship with catalytic activity, and presents the challenges of phosphide electrocatalysts in urea electrolysis.
