“…This Ag/Co(OH) 2 @NC/CC heterostructure electrocatalyst demonstrated excellent performance, mainly attributed to the 3D structure consisting of Co(OH) 2 and NC with rich ion transport pathways, the interconnected Co(OH) 2 nanosheets with a large surface area, and NC nanoflake arrays with high electrical conductivity. [82] 2D-3D heterostructure can also take the form of hollow structures, especially with nanocage morphology, resulting in a large specific surface area that can expose more active sites. The orderly arrangement of the 2D planes serves as a channel for transporting reaction substances, while also maintaining the coupling effect between planes to enhance the adsorption and desorption of intermediate products.…”

In the vast realm of scientific inquiry, the pursuit of hydrogen fuel production through electrochemical water splitting offers a promising gateway to green energy generation, alleviating the challenges posed by resource scarcity. However, conventional water splitting encounters hurdles like low efficiency and the sluggish oxygen evolution reaction (OER), which prompt searchers to seek for alternative oxidation process. Significant strides are made in conventional electrocatalytic research employing polymeric binders, resulting in commendable catalytic activity and minimal electron migration resistance. Yet, a pivotal breakthrough in this rapidly evolving field lies in the innovative conception of carbon‐based self‐supported electrocatalysts, heralding a promising trajectory ahead. This review delves into the essential electro‐activity parameters to establish the property‐activity nexus, emphasizing the benefits of self‐supported carbon‐based electrodes. Noteworthy advancements are demonstrated in electrochemical hydrogen evolution reaction (HER), OER, overall water splitting (OWS), and bifunctional HER and alcohol oxidation reaction (AOR), driven by a diverse range of self‐supported electrocatalysts. These include structure‐dependent materials such as metal oxides, hydroxides/oxyhydroxides, phosphides, sulfides, selenides, nitrides, and carbides, each meticulously tailored with nuanced modifications that shape their distinctive attributes. This field also acknowledges its challenges and opportunities, providing guidance for potential research directions and inspiring interdisciplinary collaboration among scientists.
