摘　　要：随着油气藏开采从常规油气藏逐渐转向高含硫酸性油气藏,高含硫油气藏中的硫化氢(H_(2)S)资源化利用便受到研究者的广泛关注。电催化分解H_(2)S制氢脱硫是实现H_(2)S清洁高值利用的途径之一,然而,电催化过程中的阳极钝化问题限制了其工业化发展。本文对电催化分解H_(2)S的方法特点、反应机理和研究进展进行了概述和总结。光伏驱动电催化间接分解H_(2)S制氢脱硫技术的经济效应评价表明间接法具有一定的可行性。最后对电催化H_(2)S资源化利用未来的发展进行了展望。With the gradual shift of the exploitation of oil and gas reservoirs from conventional oil and gas reservoirs to high-sulfur acidic ones,the resource utilization of hydrogen sulfide(H_(2)S)in high-sulfur oil and gas reservoirs has attracted more and more attention of researchers.Electrocatalytic decomposition of H_(2)S for hydrogen production and desulfurization is one of the effective ways to realize clean and high-value utilization of H_(2)S waste gas.However,anodic passivation problem of electrocatalysis process limits the development of its industrialization.In this paper,the characteristics,reaction mechanism and research progress of the electrocatalytic decomposition of H_(2)S were summarized.The indirect decomposition method of H_(2)S driven by photovoltaic power supply is proved to be feasible by economic effect evaluation.Finally,the challenges and prospects of the resource utilization of H_(2)S were prospected.
