Abstract
With the ever-growing global demand for sustainable energy solutions, hydrogen has garnered significant attention as a clean, efficient, and renewable energy source. In the field of hydrogen production, catalyst research stands out as one of the foremost areas of focus. In recent years, the preparation of electrocatalysts using ionic liquids (ILs) and deep eutectic solvents (DESs) has attracted widespread attention. ILs and DESs possess unique physicochemical properties and are recognized as green media as well as functional materials. Cobalt-based catalysts have proven to be efficient electrocatalysts for water splitting. Incorporating ILs or DESs into the preparation of cobalt-based catalysts offers a remarkable advantage by allowing precise control over their structural design and composition. This control directly influences the adsorption properties of the catalyst's surface and the stability of reaction intermediates, thereby enabling enhanced control over reaction pathways and product selectivity. Consequently, the catalytic activity and stability of cobalt-based catalysts can be effectively improved. In the process of preparing cobalt-based catalysts, ILs and DESs can serve as solvents and templates. Owing to the good solubility of ILs and DESs, they can efficiently dissolve raw materials and provide a special nucleation and growth environment, obtaining catalysts with novel-structures. The main focus of this review is to provide a detailed introduction to metal cobalt and its oxide/hydroxide derivatives in the field of water splitting, with a particular emphasis on the research progress achieved through the utilization of IL and DES. The aim is to assist readers in designing and synthesizing novel and high-performance electrochemical catalysts.
随着全球对可持续能源解决方案的需求不断增长,氢气作为一种清洁、高效和可再生的能源备受关注。在制氢领域,催化剂研究是最受关注的领域之一。近年来,利用离子液体(ILs)和深共晶溶剂(DESs)制备电催化剂引起了广泛关注。离子液体和 DESs 具有独特的物理化学特性,是公认的绿色媒介和功能材料。钴基催化剂已被证明是高效的水分离电催化剂。在钴基催化剂的制备过程中加入 IL 或 DES,可以精确控制其结构设计和组成,因而具有显著的优势。这种控制会直接影响催化剂表面的吸附特性和反应中间产物的稳定性,从而加强对反应途径和产物选择性的控制。因此,可以有效提高钴基催化剂的催化活性和稳定性。在制备钴基催化剂的过程中,ILs 和 DESs 可用作溶剂和模板。由于 ILs 和 DESs 具有良好的溶解性,它们可以有效地溶解原材料,并提供特殊的成核和生长环境,从而获得结构新颖的催化剂。本综述的重点是详细介绍金属钴及其氧化物/氢氧化物衍生物在水分离领域的应用,特别强调利用 IL 和 DES 所取得的研究进展。目的是帮助读者设计和合成新型高性能电化学催化剂。
期刊介绍:
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
