Jin Qian is an Associate Researcher at Northwestern Polytechnical University, Xi’an, China, whose work focuses on advanced environmental catalysis, water and wastewater treatment, and sustainable energy–environment systems, as reflected by his Scopus profile showing 67 indexed publications, more than 2,549 citations across 2,127 citing documents, and an h-index of 31, indicating both productivity and sustained scholarly impact. His recent research emphasizes catalytic oxidation processes, antibiotic degradation, sulfur-driven and thiosulfate-mediated denitrification, and carbon-based functional materials for environmental remediation. In 2025 alone, he contributed to multiple high-impact studies, including dual-metal-catalyzed Fenton-like reactions on CdₓZn₁₋ₓS@biochar for efficient water purification in Applied Catalysis B: Environmental, and the development of phosphorus-strengthened nickel single-atom catalysts enabling selective nonradical generation in Advanced Functional Materials, highlighting his strong integration of materials science with environmental engineering. His work in Bioresource Technology explores microbial responses to antibiotics such as norfloxacin in sulfur-based denitrification systems and the use of iron–carbon enhanced constructed wetland microbial fuel cells for simultaneous wastewater treatment and bioelectricity generation, demonstrating a systems-level approach that bridges microbiology, electrochemistry, and process engineering. Additionally, his comprehensive review on carbon-based material additives for enhancing anaerobic digestion performance reflects his broader commitment to sustainable energy recovery from waste streams. Collectively, Jin Qian’s research advances mechanistic understanding of pollutant transformation, catalytic reaction pathways, and microbe–material interactions, while also offering scalable technological solutions for water purification, antibiotic resistance mitigation, and low-carbon energy production, positioning him as a rising contributor to the fields of environmental catalysis and sustainable environmental engineering.
