Bismuth-rich bismuth oxyhalides for environmental and energy photocatalysis

Bismuth‐Based Photocatalysts for Solar Photocatalytic Carbon Dioxide Conversion

“…[32] As shown in Figures 3a nd 4, these two BiOCl samples exhibited 2D structures. [16,20,25] Therefore, the CB positiono fB iOX photocatalysts needs to be promoted and surfacedefects should be introduced. However, {010} facets were the dominantf acets at pH 6.…”

“…[14][15][16][17][18][19][20] The size and thickness of BiOX obtained in ethylene glycol was smaller than that of BiOX obtainedi nw ater and ethanol. It can affect size, morphology,a nd surface defects.…”

“…[14][15][16][17][18][19][20] These compounds mainly exhibit layered structures and have plate-Photocatalytic CO 2 conversion into solar fuels is an effective means for simultaneously solving both the greenhouse effect and energy crisis. [14,20] The high photocatalytic performance is mainly attributed to their open crystalline structures, whichi nduce the presence of internal static electric fields, as well as the indirect opticalt ransition, which reduces the recombination of excited electrons and holes. However,s olarp hotocatalytic CO 2 conversionh as only been developed over the past five years and, until now,n or eviews have been published on bismuth-based photocatalysts for the photocatalytic conversion of CO 2 .F or the first time, solarp hotocatalytic CO 2 conversion systemsa re reviewed herein.…”

“…However,e nergy applicationso fp hotocatalysis, such as water splitting, [21,22] N 2 fixation, [23][24][25] and CO 2 conversion, [20,26] over pristine Bi-based photocatalystsa re limited due to low reductiona bilities and low electron-hole separation efficiencies.…”

“…[20] In addition, to promote electron migration to the photocatalyst surfaceand enable electron participation in reduction reactions by improving the charge-separation efficiency,c ocatalysts, surface modification,o rh eterojunctions are used.
