An overview of semiconductors/layered double hydroxides composites: Properties, synthesis, photocatalytic and photoelectrochemical applications

An enormous research effort is presently being directed towards the improvement of efficient visible light driven photocatalysts for renewable energy applications including water splitting and CO2 reduction. Hybrids of semiconductors and layered double hydroxides (LDHs) are promising nanomaterials due to their flexible properties and the large number of compositions/preparation variables obtainable for fine-tuning. Recent advancements have been confirmed that semiconductor/LDHs nanocomposites can be envisioned as the most privileged and promising novel catalysts in the photocatalytic and photoelectrochemical applications. Moreover, this study gives an advanced review important developments in the production of the LDHs/semiconductor photocatalysts for energy generation and ecological clean up, such as degradation of dyes, O-2 evolution, hydrogen production and CO2 reduction. We desire that this review article will promote the researchers to expand the applications of LDHs/semiconductor composite in the field of photocatalysis in a green approaches. (C) 2019 Elsevier B.V.
