Development of all-inorganic lead halide perovskites for carbon dioxide photoreduction

Abstract

From decades, the solar-driven conversion of carbon dioxide (CO2) into other valuable chemical products has captured enormous interest of scientists as a promising route to tackle the global warming and energy crisis. Recently, all-inorganic lead halide perovskite quantum dots (ILHP QDs) have witnessed as a new class of materials for CO2 photoreduction owing to their outstanding optoelectronic properties and low-cost solution processing. This review summarizes the physicochemical properties and synthesis approaches of the ILHP QDs together with their advantages as photocatalysts for CO2 reduction. Particularly, strategies for improving the photocatalytic activity of these semiconductors are thoroughly summarized and discussed. Finally, we focus on limitations and favourable perspectives for the rational design of perovskite-based photocatalysts.
