A halide perovskite as a catalyst to simultaneously achieve efficient photocatalytic CO₂ reduction and methanol oxidation

Abstract

We have firstly demonstrated the photocatalytic utilization of a halide perovskite for combining reduction of CO2 with selective oxidation of methanol.

Recent advances in metal halide perovskite photocatalysts: Properties, synthesis and applications

“…For example, Wu et al integrated photocatalytic CO 2 reduction with oxidative organic transformation using CdSe/ CdS QDs [192], thus enabling the full utilization of photoexcited electrons and holes to simultaneously produce CO and valueadded chemical (pinacol); Zhang et al designed an efficient InP-In 2 O 3 p-n junction photocatalytic system [193], which combined CO 2 reduction with the photooxidation reaction of tetrahydroisoquinoline to obtain high value-added gas and liquid chemicals, respectively. In very recent, Lu et al demonstrated that the CsPbBr 3 could simultaneously achieve efficient photocatalytic CO 2 reduction and methanol oxidation [194]. These strategies provide idea alternatives to the sacrificial agents.…”

Glycine‐Functionalized CsPbBr3 Nanocrystals for Efficient Visible‐Light Photocatalysis of CO2 Reduction

“…Artificial photosynthesis is presently receiving intense attention because of its great potential to meet the global demand for sustainable development, [1] accomplishing the recycling of CO 2 by employing clean sunlight energy to drive the reduction reaction of CO 2 to generate chemical energy over photocatalysts [2] . In this technology, apart from CO 2 reduction integrated with meaningful chemical reactions, [3, 4] the photocatalysis of CO 2 reduction coupled with water (H 2 O) oxidation is considered to be a dream reaction for generating solar fuels or value‐added chemical feedstocks and O 2 gas [5] . To date, various semiconductors have been exploited as photocatalysts to achieve CO 2 reduction and H 2 O oxidation simultaneously [6–8] .…”

Recent Developments in Lead and Lead-Free Halide Perovskite Nanostructures towards Photocatalytic CO2 Reduction

“…Remarkably, they have employed hexafluorobutyl methacrylate to improve NC’s stability and dispersity in an aqueous medium. Then, in this class of materials, Zhang and coworkers reported Co-doped CsPbBr 3 embedded in the matrix of Cs 4 PbBr 6 (a surface protector) [ 66 ]. The reason behind such protection of Cs 4 PbBr 6 was to improve the stability of ligand-free CsPbBr 3 perovskite.…”
