Increasing environmental pollution and shortage of conventional fossil fuels have made it urgent to develop renewable and clean energy sources. Electrocatalytic water splitting, with its abundant raw materials, simple process, and zero carbon emission, is considered one of the most promising processes for producing carbon-neutral hydrogen which has excellent energy conversion efficiency and high gravimetric energy density. Among them, oxygen evolution reaction (OER) electrocatalysts and hydrogen evolution reaction (HER) electrocatalysts are critical to decreasing the intrinsic reaction energy barrier and boosting the hydrogen evolution efficiency. Therefore, it is imperative to develop and design low-cost, highly active, and stable OER and HER electrocatalysts to lower the overpotential and drive the electrocatalytic reactions. Transition metal sulfides, especially iron-based sulfides, have attracted extensive exploration by researchers as a result of its high abundance in the Earth's crust and near-metallic conductivity. Consequently, in this review, we systematically and comprehensively summarize the progress in the application of iron-based sulfides and their composites as OER and HER electrocatalysts in electrocatalysis. Detailed descriptions and illustrations of the special relationships among their composition, structure, and electrocatalytic performance are presented. Finally, this review points out the challenges and future prospects of iron-based sulfides in practical applications for designing and fabricating more promising iron-based sulfide OER and HER electrocatalysts. We believe that iron-based sulfide materials will have a wide range of application prospects as OER and HER electrocatalysts in the future.

碳抵消机制是应对气候变化领域的新生事物,其为我国碳排放配额交易市场的重要补充。在实现“双碳”目标下,我国碳抵消机制的法律保障是确保我国碳排放权交易市场稳定的重要问题。文中研究发现,我国碳抵消机制中碳减排量的法律属性不明、政策指导下碳抵消机制规范性与系统性不足以及碳减排量交易市场拓展受限等问题,阻碍我国双碳法治建设与碳交易市场的稳定有序。在积极稳妥推进碳达峰碳中和战略的时代背景下,通过分析我国碳抵消机制法律保障的必要性,从规范与学理层面明确碳减排量的用益物权属性,构建体系化的碳抵消机制法律制度。同时,确立多元化碳减排量权利主体共有制度,搭建全国统一的市场交易平台,以稳定碳减排量市场交易价格,并形成有效的市场监督框架,有序拓展我国碳减排量交易市场,完善我国碳排放权交易市场,向碳中和乃至净负排放稳定过渡,逐步健全能源安全与气候安全法律体系。
