He has authored/co-authored 70 SCI-indexed publications in high-impact journals such as Advanced Functional Materials, Angewandte Chemie International Edition, and Advanced Energy Materials, with multiple articles appearing in Applied Catalysis B: Environmental, Chemical Engineering Journal, and Journal of Hazardous Materials.
主讲内容简介：
This lecture will systematically address critical challenges and breakthroughs in amine-functionalized metal-organic framework heterojunctions for selective solar-driven CO2 reduction. Key highlights include: (1) Novel amine functionalization strategies to modulate Cr-3d electronic states and establish dynamic -NH2/-NH3+ proton relays for suppressing competitive hydrogen evolution, (2) Mechanistic insights into S-scheme charge transfer dynamics via femtosecond transient absorption spectroscopy and operando X-ray photoelectron spectroscopy, and (3) Synergistic effects of MOF/g-C3N4 heterojunctions in simultaneously enhancing photocatalytic CO₂-to-CO selectivity and solar-to-fuel conversion efficiency.
