CHEMELECTROCHEM(2024)
Abstract
Over the past decades, tremendous effort has been made to enhance the water-splitting via fabricating eco-friendly electrocatalyst with increased conductivity, and large number of accessible active sites in lab scale. However, the development of earth abundant efficient electrocatalyst with superior activity for -seawater-splitting remains a great challenge for the researchers. In this regard, self-supported catalysts are found to be the most promising candidates, they have the features of increased loading, superior adhesion, rapid mass and charge transfer, and easy wettability for large scale hydrogen production via electrochemical seawater splitting. This review investigates different fabrication processes for the self-supported catalyst, emphasizing their distinct characteristics that contribute to improved activity. Furthermore, we provided a detailed elucidation of the procedure and characteristics of seawater splitting, emphasizing the most recent progress in the creation of self-supportive catalyst for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and bifunctional activity. We have also examined the current barriers and potential prospects for advancing the utilization of self-supported catalysts in the process of seawater splitting. Self-supported catalysts are the best candidates for large-scale hydrogen production through electrochemical seawater splitting because to their increased loading, adhesion, mass and charge transfer, and wettability. The present review investigates the methodologies for producing self-supported catalysts and explores their distinctive characteristics that enhance catalytic activity along with the upcoming challenges in self-supported catalyst for seawater splitting.+ image
