The generation of ammonia, hydrogen production and nitrogen purification are considered as energy intensive processes accompanied with large amount of CO₂ emission. The electrochemical method assisted by photo energy has been widely utilized for the chemical energy conversion. In this work, the earth-abundant iron pyrite (FeS₂) nanocrystals grown on carbon fiber paper (FeS₂/CFP) was found to be an electrochemical and photoactive catalysts for nitrogen reduction reaction (NRR) under ambient temperature and pressure. The electrochemical results revealed that FeS₂/CFP achieved a high Faradaic efficiency (FE) ~14.14% and NH₃ yield rate~ 0.096 mg/min at −0.6 V versus RHE electrode in 0.25 M LiClO₄. During proceeding electrochemical catalytic reaction, the crystal structure of FeS₂/CFP remained cubic pyrite phase analyzed by in-situ XRD measurement. Also, With near infrared laser irradiation (808 nm), NH₃ yield rate of FeS₂/CFP catalyst can be slightly improved to (0.1 mg/min) with high FE of 14.57%. Furthermore, density functional theoretical (DFT) calculations demonstrated that N₂ molecule had strong chemical adsorption energy on the iron atom of FeS₂. Overall, the iron pyrite-based materials have proven to be a potential electrocatalyst with photoactive behavior for ammonia production in practical applications.
