Abstract:

Realizing high-efficiency H₂ production under practical, mild conditions is essential to meet the requirements to develop this source of ideal clean, alternative energy; thus, this attracted wide spread interest. Catalytic decomposition of formic acid-formate is one of the most widely studied options to achieve this. Herein, we demonstrate H₂ production from HCOOK over Pd/C catalysts, in which a flexible content is allowed by modulating the catalyst preparation conditions, reaction conditions, and catalytic characterizations. This experiment not only includes basic chemical kinetics but also guides students to accumulate innovative consciousness through thinking about the structure-activity relationship of catalysts by structural characterization. In addition, this experiment enriches teaching content, improves teaching efficiency, and exercises students' cooperation ability through modular design and group teaching. This project relies on the National Demonstration Center for Experimental Education to build an inter-school resource sharing platform to realize the sharing of experimental data and characterization results that colleges can then use to freely select the required information to enrich students' experiment reports.
