Abstract: This comprehensive chemistry experiment utilizes vanadium trichloride and hexamethylenetetramine as precursors to synthesize a heterostructured composite material consisting of nano-scaled vanadium nitride particles embedded in nitrogen-doped carbon sheets through template-assisted heat treatment and nitridation methods. Furthermore, the electrocatalytic nitrogen reduction performance of the composite material is thoroughly examined. The experimental procedure encompasses interdisciplinary knowledge and practical skills in inorganic chemistry, physical chemistry, and analytical chemistry, with a focus on cutting-edge scientific research. By stimulating students’ interest in learning and enhancing their application abilities, this experiment aims to cultivate students’ disciplinary literacy, research innovation capabilities, and sense of social responsibility.

Key words: Vanadium nitride, Nitrogen-doped carbon, Electrocatalysis, Comprehensive chemical experiment
