摘要
为了解决能源危机问题,提出了电解水技术开发清洁可持续氢能的终极途径。电催化析氧反应(oxygen evolution reaction,OER)是电解水制氢技术的瓶颈,二硫化钼(MoS_(2))在电化学OER方面得到广泛研究,然而其析氧过电位普遍高于300 mV,限制了其应用。对MoS_(2)材料用于OER的最新发展进行了论述和总结,分析了本征MoS_(2)材料、金属掺杂、异质材料等改性策略及结果,提出了MoS_(2)基催化剂在全pH介质OER研究中存在的问题,展望了OER催化剂未来的发展趋势,给出了合理设计和高效改性催化剂的思路。
On the issues of energy crisis,water splitting technology was considered as the ultimate way to produce clean and sustainable hydrogen energy.Electrochemical oxygen evolution reaction(OER)has been the bottleneck of water splitting.Though molybdenum disulfide(MoS_(2))has been widely investigated in the field of electrochemical OER,the OER overpotential of more than 300 mV limits its application.The recent development of MoS_(2)-based catalysts was discussed and summarized.The modified strategies and results of pristine MoS_(2),metal doped MoS_(2) and heterogeneous MoS_(2) hybrids were analyzed.The issues of MoS_(2)-based OER catalysts in all pH range were proposed.The developing tendency of OER catalysts was prospected,and the idea of reasonable design and efficient modification was put forward.
