Aqueous Zn-ion battery, characterized by high safety, low cost, and environmental friendliness, exhibit broad application prospects in fields such as large-scale energy storage and wearable devices. Our research team focuses on the key scientific issue of Zn anode interface stability, systematically exploring multidimensional synergistic optimization strategies, including hydrogel electrolytes, electrolyte additives, and artificial anode interfacial layers, to regulate the interfacial reaction behavior at the anode/electrolyte interface. To address the side reactions that readily occur during Zn plating/stripping, such as dendrite growth, hydrogen evolution, and surface corrosion, we develop hydrogel electrolyte systems that combine high ionic conductivity with good mechanical flexibility, introduces functional additives to modulate the solvation structure of zinc ions and the interfacial electric field distribution, and designs artificial interfacial layers to achieve uniform Zn deposition morphology and optimized interfacial chemical environments. By coupling these multiple strategies, this work aims to enhance the controllability and reversibility of the Zn anode interfacial reactions, thereby providing theoretical foundations and technical support for the development of long-cycle-life and high-safety aqueous Zn-ion batteries.

We conduct systematic studies on catalyst design, interfacial microenvironment engineering, and reaction mechanism elucidation. By developing advanced materials such as single-atom catalysts, defect-engineered nanomaterials, heterostructured electrodes, and functional gel electrolytes/interfacial materials, and integrating in situ Raman and infrared spectroscopies with theoretical simulations, we aim to uncover the evolution of reaction intermediates, surface reconstruction processes, and the role of local water/ion environments in governing catalytic performance. Furthermore, targeting metal–air batteries, water splitting, and electrocatalytic small-molecule coupling systems, we explore multi-reaction synergy, multi-interface regulation, and integrated energy storage–catalysis platforms, with the goal of advancing sustainable energy conversion and green chemical manufacturing.

Photocatalytic technologies use semiconductors to convert solar energy into chemical energy for addressing energy and environmental challenges. Our group focuses on both direct and coupling conversion reactions. The direct conversion reactions include N2 reduction to NH3, CO2 reduction to CO and CH4, etc, O2 reduction to H2O2, and H2O oxidation to H2O2. Furthermore, the coupling conversion pathways encompass both C–C and C–N coupling reactions. To address key challenges in photocatalytic systems, such as low charge carrier separation efficiency and sluggish surface reaction kinetics, various strategies, such as defect engineering, surface engineering, and heterojunction engineering, have been proposed for semiconductors to improve their photoactivity. Through these approaches, we systematically investigated the mechanisms responsible for improved photocatalytic performance, thereby providing new scientific insights and innovative approaches for the green synthesis of high-value-added products.
