摘要:

作为未来最有潜力的制氢技术之一,电解水为解决环境污染和能源危机等问题提供了一种有效的解决途径。然而,阳极析氧反应缓慢的动力学和较高的过电位使其成为电解水装置效率提升的主要瓶颈。因此,开发高活性和高稳定性的析氧反应催化剂对于电解水技术的发展具有重要意义。近年来,镍基金属有机框架材料因其具有丰富可调的拓扑结构、较大的比表面积以及多孔特性,在催化领域受到了越来越多的关注。本文综述了镍基金属有机框架及其衍生材料在析氧催化研究中的最新进展。首先简要介绍了镍基材料在析氧反应中的原理及评价析氧催化剂活性的一些重要参数,并列举了几种镍基金属有机框架材料的结构及其在催化中的优势。随后,结合近年来发表的文献,对单金属、双金属和三金属镍基金属有机框架材料及其衍生物在析氧催化中的研究进展进行了总结与讨论,重点分析了该类材料的设计策略和催化机理。最后对该领域目前所面临的主要挑战以及未来的发展趋势进行了总结与展望。

Abstract:

As one of the most promising hydrogen production technologies, electrochemical water splitting is an effective measure for solving environmental pollution and energy crises. However, the slow kinetics and high overpotential of the oxygen evolution reaction (OER) are the primary deterrents for improving the efficiency of water splitting devices. Iridium- and ruthenium-based noble metal catalysts are extremely expensive, which limits the industrial-scale development of this technology. Therefore, the development of oxygen evolution catalysts with high activity, excellent stability, and low costs is significantly important for water splitting technologies. Nickel-based materials meet the requirements of high abundance, cost-effectiveness, and high activity. In recent years, nickel-based metal organic frameworks (Ni-based MOFs) have attracted increasing research attention owing to their diverse and tunable topological structures and large specific surface areas. Furthermore, the mesoporous three-dimensional structure of MOFs can promote the diffusion of reactants, rendering them excellent candidates for catalytic applications. In order to utilize the advantages of Ni-MOFs more efficiently, the following methods are usually used to improve their catalytic performance. Owing to their unique properties, metal nodes can be replaced without affecting the MOF skeleton. As iron series metals, Co and Fe doping show unique catalytic activity and structural stability due to the synergistic effect between metal centers. Further, Ni-MOFs can simultaneously be used as precursors for oxidation, phosphating, or vulcanization to obtain Ni-MOF derivatives with different components. Among them, high-temperature carbonization treatment can make use of abundant organic ligands of Ni-MOFs to form a partially graphitized carbon-based framework, thereby augmenting conductivity, preventing the aggregation and corrosion of transition metals, and improving the overall support strength. The catalytic performance of oxygen production can be further improved by directly growing the Ni-MOFs on the substrate and introducing other active substances or conductive materials. Herein, the latest developments of Ni-based MOFs and their derivatives have been reviewed with regard to their utilization in OER catalysis, including nickel oxides, nickel hydroxides, nickel phosphides, nickel sulfides, and carbon composite materials. First, the mechanism and measurement criteria of the OER are briefly introduced. Second, the structures of several typical Ni-based MOFs (MOF-74, MILs, PBAs, and ZIFs) and their preparation methods are described. Subsequently, recent advances in the application of Ni-based MOFs and their derivatives in the OER are discussed, with an emphasis on materials design strategies and catalytic mechanisms. Finally, the main challenges and opportunities in this field are proposed.
