Pollution and the rising energy demand are two major society issues, requiring urgent solutions. Here, we review the simultaneous production of hydrogen and removal of pollutants, with a focus on mechanisms, synthesis of photocatalysts, and applications. Remarkably, this method utilizes organic pollutants as sacrificial agents for photocatalytic hydrogen production, thus both reducing pollution and producing energy. Metal-doped, cocatalyst-loaded, organic and inorganic composite, heterostructure and heterojunction photocatalysts are described. We present applications to the removal of antibiotics and organic dyes. Pollutant degradation rates range from 5.3 to 100%, with hydrogen evolution of 13.7–2724.89 μmol·g^–1h^–1.

污染和不断增长的能源需求是亟待解决的两大社会问题。在这里，我们回顾了同步制氢和去除污染物的过程，重点关注光催化剂的机理、合成和应用。值得注意的是，该方法利用有机污染物作为光催化制氢的牺牲剂，从而既减少了污染又产生了能源。描述了金属掺杂、负载助催化剂、有机和无机复合材料、异质结构和异质结光催化剂。我们展示了去除抗生素和有机染料的应用。污染物降解率为5.3%~100%，析氢量为13.7~2724.89 μmol·g ^–1 h ^–1 。
