Abstract: A comprehensive chemical experiment was designed based on scientific research achievements to investigate the controllable preparation of LDHs (highly dispersed layer double hydroxides)-based catalysts and the catalytic reduction of nitro compounds. The experiment involves the synthesis of inorganic functional materials and catalytic materials, characterization of crystal structure, morphology, and chemical bonds of the catalytic materials, evaluation of catalytic reaction performance, and kinetic studies. By conducting this experiment, students are enabled to grasp scientific research methods, enhance their ability to think independently and explore innovative ideas, and develop skills in practical problem-solving using their knowledge of chemistry. This experiment plays a significant role in fostering the cultivation of high-quality and innovative composite talents in the new era.

Key words: Layered double hydroxides, Highly dispersed Ni-Cu catalysts, Reduction of nitro compounds, Separate nucleation and aging steps, Comprehensive chemical experiment
