| 英文摘要 | Water pollution has emerged as a severe global issue. Biologically synthesized metal sulfides have been recognized as a promising alternative in wastewater treatment due to their low cost, rapid effectiveness, and enhanced environmental compatibility. The present study focuses on novel sulfate-reducing bacteria-regulated Cu2O-doped Cu2S in situ on copper mesh (CSOCM-SRB) synthesized by a two-step electrochemical method. The resultant CSOCM-SRB showed high Fenton-like activity for organic dye degradation and bacterial disinfection. The electrochemical synthesis parameters for CSOCM-SRB were optimized. Effective methylene blue (MB) degradation (99.5 % in 120 min) is achieved at 0.07 M H2O2 with 0.4 cm(2)/mL CSOCM-SRB when pH= 4 at 45 degrees C. High antimicrobial efficacy, up to similar to 100 % against Escherichia coli is also obtained in 4 min. EPS from SRB participate in the CSOCM-SRB formation and are closely related with S compounds and S vacancies in CSOCM-SRB, which significantly contribute to the high Fenton-like activities. It is proved that O-1(2) and center dot OH played pivotal roles while center dot O-2 also contributed in the Fenton-like reaction. The proposed SRB-regulated Cu2O-doped Cu2S nanocubes holds substantial potential for wastewater treatment and the development of novel catalytic materials. |
