Abstract: In response to the demands of “emerging engineering education”, this study presents a comprehensive undergraduate chemistry experiment that integrates cutting-edge research on carbon-based nanomaterials with metallic zinc-air batteries. Iron phosphide@carbon nanotubes composites were synthesized using chemical oxidation polymerization and high-temperature pyrolysis. The resulting composite serves as an electrocatalytic material for the cathode of zinc-air batteries. This experiment aims to help undergraduate students understand the latest developments in the new energy battery industry, become familiar with the assembly and performance testing of zinc-air batteries, apply theoretical knowledge in practical contexts, and cultivate their analytical, problem-solving, and innovative skills, thereby enhancing their overall scientific literacy.

Key words: Zinc-air battery, Carbon nanotube, Iron phosphide, Comprehensive chemical experiment
