Tailoring Inorganic Halide Perovskite Photocatalysts toward Carbon Dioxide Reduction

Abstract

In recent years, photocatalytic carbon dioxide reduction has emerged as an attractive strategy to settle the global warming and energy crisis by converting CO2 into valuable chemicals utilizing solar energy. All‐inorganic halide perovskites (PVKs), as a class of promising light‐harvesting materials with outstanding optoelectronic properties and considerable stabilities, have received dramatic attention in the field of photocatalytic CO2 reduction reaction (CO2RR). In this review, the recent progress of PVK catalysts for CO2RR is systematically summarized and evaluated according to the modification strategies and their mechanisms. The working principles of CO2RR are first introduced. The main strategies for improving the photoelectrochemical performance are then discussed and their recent developments are summarized. Finally, the current challenges, including instability, charge recombination, and insufficient active sites, and future research opportunities for further development are addressed.

Halide perovskite quantum dots for photocatalytic CO2reduction

“…Inspired by this strategy, research on photocatalytic CO 2 reduction of halide perovskite QDs boomed rapidly. 24,49 Apart from instability in a polar solvent, perovskite materials would also decompose rapidly when exposed to moisture, heat, light, and oxygen. 50 decomposition, and oxidation.…”

AI for Nanomaterials Development in Clean Energy and Carbon Capture, Utilization and Storage (CCUS)

“…A potential challenge for ML-aided photocatalyst screening is the shortage of available data. However, the usage of DFT for photocatalyst evaluation and mechanism discovery is becoming increasingly popular, and the results from DFT calculations could become one major data source . Furthermore, DFT calculations for photocatalysts often use HSE-06 functional, which is more time-consuming than normal PBE calculations in other heterogeneous catalysis calculations.…”

NaBr-Assisted Aqueous Synthesis of Perovskite-Embedded PbBr(OH) Hierarchical Nanostructures for Dye Photodegradation

“…Halide perovskite nanomaterials have shown promising optoelectronic applications in photovoltaics, light-emitting diodes, photodetectors, and lasers due to their exceptional optical and semiconducting properties, such as high photoluminescence quantum yield, large carrier mobility, narrow full width at half-maximum (FWHM), high light absorption coefficient, and tunable band gap. − Very recently, perovskite-based compounds have shown great potential in photocatalytic applications. − Various halide perovskites such as CsPbBr 3 , CsPbI 3 , methylammonium lead iodide (MAPbI 3 ), formamidinium lead bromide (FAPbBr 3 ), Cs 2 AgBiBr 6 , etc. have been investigated as promising photocatalysts in hydrogen generation, − dye photodegradation, − photocatalytic CO 2 reduction, − and organic synthesis. − By employing MAPbI 3 and visible light, Nam and co-workers reported the photocatalytic hydrogen evolution from hydroiodic acid . Xu et al investigated the CO 2 photocatalytic reduction toward CO formation using CsPbBr 3 as the photocatalyst .…”
