Hydrogen Production from Formate Decomposition Catalyzed by Carbon-Supported Pd

实现温和条件下高效制氢,是满足人类对清洁、绿色新能源需求的关键,是当今国际研究热点。而催化甲酸-甲酸盐等含氢物质分解制氢,是实现上述目标的重要途径之一。本项目设计了一个教学时长灵活、实验内容丰富的钯碳催化甲酸钾分解制氢实验,探究催化剂制备、反应条件对催化活性影响以及反应动力学规律等。本实验不仅包含物理化学中动力学相关内容,还通过表征手段,引导学生对催化剂构效关系进行思考,增强创新意识。此外,本实验通过模块化设计,提倡组员分工协作,丰富教学内容、提高教学效率、锻炼学生合作能力。本项目可依托国家级教学实验示范中心搭建校际资源共享平台,实现实验数据共享、表征结果共享,各高校可自由选取需要的信息,充实学生课后实验报告。

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.
