Abstract

Abstract:

In the context of innovative education, the electrocatalytic reduction of nitrate for ammonia synthesis is taken as a case example to integrate research outcomes into experimental teaching. On the basis of students' pre-existing experimental skills and foundational electrochemical knowledge, electrochemical measurement, nuclear magnetic resonance spectroscopy, ultraviolet spectrophotometry and other techniques are used to evaluate the performance of catalysts for nitrate electroreduction to ammonia. Students can further understand the basic principle of electrocatalysis, master the electrochemical measurement method via this experiment and stimulate their interests in electrosynthesis. The content of this teaching experiment is informative and involves multidisciplinary knowledge. It can satisfy the needs of interdisciplinary integration and cultivate the divergent thinking of students, which meets the requirements of subject education in the new area.

Key words: Electrocatalysis, Nitrate reduction, Ammonia, Electrochemical measurement technique
