In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global energy problem, while only releasing environmentally benign water. Accordingly, popularizing this subject and educating students with the knowledge of this powerful technology are urgently needed. In this paper, Pt-loaded commercial titanium dioxide (P25) is used as the photocatalyst to explore the process of photocatalytic hydrogen evolution. A simple experimental demonstration is presented, integrating photocatalytic hydrogen production with a hydrogen fuel cell system in chemistry class. This experiment is suitable for use with undergraduate students as a systematic and basic laboratory experience or as a demonstration for primary/middle/high school students to stimulate their research interests in field of renewable energy. The principles and reaction mechanisms involved in both photocatalytic water splitting and hydrogen fuel cell operation, as well as the experimental design to link photocatalysis with fuel cells, are systematically discussed.

与氢燃料电池串联的光催化制氢实验示范
近年来,太阳能光催化分解水制氢作为提供清洁能源和减少环境污染的方法备受关注。这种由太阳能驱动合成氢气的方法是完全可再生的,可用于为氢燃料电池提供动力,有效解决全球能源问题,同时只释放对环境无害的水。因此,迫切需要普及这门学科,并向学生传授这项强大技术的知识。在本文中,载铂的商业二氧化钛(P25)被用作光催化剂来探索光催化析氢的过程。提出了一个简单的实验演示,将光催化制氢与化学课上的氢燃料电池系统相结合。本实验适合本科生作为系统的基础实验体验,或作为中小学生的示范,激发他们在可再生能源领域的研究兴趣。系统地讨论了光催化水分解和氢燃料电池操作所涉及的原理和反应机制,以及将光催化与燃料电池联系起来的实验设计。
