E-wastes comprise complex combinations of potentially toxic elements that cause detrimental effects of the environmental contamination; besides their posing threat, most of the products also contain valuable and recoverable materials (Li, Au, Ag, W, Se, Te, etc.), which make them distinct from other forms of industrial wastes. Most of these value-added elements which are primarily employed in electronic goods are disposed of by incineration and land-filling. This is a serious issue besides just environmental pollution, as IUPAC recognized that such ignorance of or poor attention to e-waste recycling has put several elements in the periodic table to the list of endangered elements. Recycling these wastes utilized for electrocatalytic water splitting to produce H₂. These recovered e-wastes materials are used as electrocatalysts for the water-splitting, additives to enhance reaction kinetics, and substrate electrodes as well. Recycling and recovery of value-added materials in the view of applying them to electrocatalytic water splitting with endangered elements' perspective have not been covered by any recent review so far. Hence, this review is dedicated to discussing the opportunities available with recycling e-wastes, types of value-added materials that can be recovered for water splitting, strategies exploited, and prospects are discussed in details.

电子废物包含对环境污染造成不利影响的潜在有毒元素的复杂组合；除了构成威胁外，大部分产品还含有有价值的可回收材料（锂、金、银、钨、硒、碲等），这使它们与其他形式的工业废物有所区别。这些主要用于电子产品的增值元素大部分都通过焚烧和填埋处理。除了环境污染之外，这是一个严重的问题，因为 IUPAC 认识到，对电子废物回收的这种忽视或不重视已经将元素周期表中的几个元素列入了濒危元素清单。回收这些用于电催化分解水以生产 H _{2 的}废物. 这些回收的电子废物材料用作水分解的电催化剂、增强反应动力学的添加剂和基板电极。到目前为止，从濒危元素的角度来看，从将增值材料应用于电催化水分解的角度来看，增值材料的回收和回收尚未被任何最近的评论所涵盖。因此，本次审查致力于讨论回收电子废物的机会、可回收用于水分解的增值材料类型、所利用的策略，并详细讨论了前景。
