Spontaneous Oxidative Reconstruction of FeS2 speeds up High-Efficiency Nitrate Reduction

Abstract

Electrocatalytic nitrate reduction (eNO3RR) relies on multi-tasking function to overcome the difficulty of electron/mass transfer, but catalyst of single metal element could not achieve. Spontaneously oxidative reconstruction endowed catalyst for multitasking capabilities, enhancing performance of eNO3RR. The spontaneously reconstructed S-FeOOH achieves outstanding eNO3RR performance (FE.= 93.7% and yield = 80.2% of NH3), providing new design principles for high-performance nitrate reduction catalysts.
