Fe(III)-C3N4 hybrids photocatalyst for efficient visible-light driven nitrogen fixation

Abstract

Solar-driven reduction of nitrogen to ammonia is a promising strategy for energy storage and conversion. Herein, a new strategy of modifying Fe(III) onto carbon nitride is reported showing enhanced photocatalytic nitrogen fixation. The Fe(III) and nitrogen vacancies narrow down the carbon nitride intrinsic bandgap and suppress the radiative electron-hole recombination. Fe(III)-C3N4 therefore shows potential as a new high-efficiency artificial photosynthesis ammonia.
