Abstract

Highlights: Recent progress in the architectural design process of solitary LDH based photocatalytic materials for photocatalytic/photoelectrochemical water splitting is summarized. Critical challenges and future outlook concerning to these classes of materials are outlined for future research, novel opportunities and applications in this field of research. Abstract: Sun light-driven photocatalytic and photoelectrochemical water splitting are propitious towards solar to chemical energy conversion. Incorporating solitary photoelectrode or dispersed photocatalyst emulated the properties of visible light harvester, together with transporting photogenerated charge carriers for activating the redox activities. Consequently, indulgent the correlation among intrinsic structural behavior, performance and stability of photoelectrodes/photocatalyst is essential. Hence, layered double hydroxides (LDHs) as one of the propitious photocatalysts intensively researched due to their layered structure and excellent physicochemical properties. Here, this review summarizes the simplified synthesis strategy to fabricate solitary LDHs semiconductor photocatalyst covering optical and morphological aspects towards superior photocatalytic and photoelectrochemical water splitting activities. Initially, the review outlines photocatalytic and photoelectrochemical energy conversion mechanism along with the synthetic methods to highlight the present status of the LDHs for practical application. Afterward, tactics in the synthetic technique of solitary LDHs and their photocatalytic and photoelectrochemical water splitting performances have been reviewed.
