Photoreduction　of　CO2　into　value-added　fuels　under　mild　conditions　is　a　promising　route　to　relieve　the　pressure　from　extensive　CO2　emission　and　energy　consumption,　but　the　rational　design　of　novel　photocatalysts　for　efficient　CO2　reduction　remains　a　big　challenge.　Herein,　a　series　of　transition　metal　doped　In2O3/C　(M　=　Fe,　Cu,　and　Zn)　photocatalysts　are　prepared　based　on　a　bimetallic　metal-organic　framework　template,　where　the　rearrangement　of　electron　density　distribution　is　facilely　achieved　via　doping　metal　atoms.　Correspondingly,　the　broadened　light-harvesting　scope,　charge　transfer　rate,　and　produced　intermediates　in　photocatalytic　CO2　reduction　can　be　optimized.　In　particular,　Cu-In2O3/C　exhibits　a　largely　improved　CO　yield　with　a　high　selectivity,　which　is　superior　to　that　of　most　of　the　previously　reported　photocatalysts　derived　from　MOFs.　This　work　thus　provides　an　efficient　approach　for　tailoring　the　electronic　structure　of　photocatalysts,　which　shows　promising　applications　in　carbon　cycling.
