Design　and　construction　of　visible-light-responsive　and　low-cost　catalyst　to　improve　photocatalytic　CO2　reduction　efficiency　are　highly　urgent　due　to　rapid　increment　of　CO2　emission.　Herein,　a　facile　but　effective　strategy　is　proposed　to　synthesize　heteroatoms-doped　porous　treated　rape　pollen　(TRP)　and　NH2-functionalized　TRP　for　CO2　reduction.　Heteroatoms　doping　can　accelerate　photoinduced　charge　transfer　between　neighboring　carbon　atom.　The　introduction　of　NH2-　group　offers　effective　sites　to　boost　CO2　adsorption,　which　is　beneficial　to　facilitate　CO2-to-CO　conversion.　The　experimental　results　indicate　that　TRP-NH2　exhibits　visible-light-driven　CO　formation　rate　of　1165.3　μmol　h−1　g−1　in　the　gas-solid　reaction　system　without　co-catalysts　or　sacrificial　agents,　which　is　2.4　and　70.1　times　than　those　of　TRP　(488.4　μmol　h-1　g-1)　and　g-C3N4　(16.6　μmol　h-1　g-1),　and　exceeds　reported　state-of-the-art　carbon-based　photocatalysts.　The　theoretical　investigation　shows　that　the　incorporation　of　NH2-　group　can　improve　its　charge　density　and　converge　more　electrons　to　adsorb　CO2　molecules.　In　situ　Fourier　transform　infrared　(FT-IR)　spectroscopy　spectra　disclose　that　the　COOH*　radical　is　the　main　intermediate.　The　findings　reveal　the　correlation　between　surface　NH2-　group　and　photocatalytic　CO2　reduction　performance　and　can　be　extended　to　other　sustainable　metal-free　based　catalysts　for　solar-driven　CO2　reduction.　©　2021
