Saleh, Tawfik A. | Fadillah, Ganjar
Nanocomposite materials have received much attention from scientists and engineers interested in the detection and photoreduction of CO₂ compounds. Their interest is due in large part to the unique properties of these materials, including their high degree of photoactivity, thermal stability, high surface area, and malleability. In the present review, we focus on several nanocomposite types used for the detection and photochemical reduction of CO₂: titania-based nanocomposites, chalcogenide-based nanocomposites, LDHs-based nanocomposites, and MOFs-based nanocomposites. More specifically, trends in green synthesis nanocomposites, methods for detecting CO₂ compounds, and the photoreduction of those compounds are summarized in this paper. Several modified approaches to nanocomposite materials have been discussed to achieve optimum results. Generally, we find that the presence of functional active groups, doping metal, and other semiconductor materials act as catalysts, significantly enhancing the photoreduction properties of nano-materials. Moreover, we will also discuss additional challenges, especially in regard to large-scale industrial applications. In our discussion, we will highlight the use of nanocomposite-based materials in the detection and photoreduction of CO₂. It is hoped that our findings will serve as a reference and inspiration for academic researchers and industrial professionals.
