Our research has focused on developing MOF-derived materials for energy storage and conversion applications with improved electrochemical performance. Through various synthesis methods, including direct carbonization, template-assisted synthesis, and chemical activation, we have prepared MOF-derived carbon-based materials with high specific surface area, pore volume, and conductivity, which are crucial factors for enhancing electrochemical performance in energy storage devices. For example, wevhave used a self-templating method to prepare hollow ordered mesoporous carbon (HOMC) materials with high N-doping, which have demonstrated superior electrochemical performance for supercapacitors. In addition, I have explored the potential of sulfides in energy storage and conversion, constructing a dual-modulated NiCo2O4@NiCo2S4 heterostructure and incorporating sulfur vacancies in CuCo2S4 hollow nanoarchitectures to achieve enhanced electrochemical performance. Furthermore, we have explored interfacial coupled engineering of plasmonic amorphous MoO3-x nanodots/g-C3N4 nanosheets for photocatalytic water splitting and photothermal conversion, developing highly active photocatalysts with excellent electrochemical performance. Overall, our research has demonstrated the great potential of MOF-derived materials, sulfides, and their heterostructures for energy storage and conversion applications, with publications in prestigious journals such as Energy Storage Materials, Carbon Energy, Advanced Energy Materials, and Small.

我们的研究重点是开发用于储能和转换应用的MOF衍生材料，并改善了电化学性能。通过各种合成方法，包括直接碳化，模板辅助合成和化学激活，我们准备了具有高比表面积，孔隙体积和电导率的MOF衍生的碳基材料，这是增强能源存储设备中电化学性能的关键因素。例如，Wevhave使用一种自我示意方法来制备具有高N兴奋剂的空心有序的介孔碳（HOMC）材料，这些材料表现出了超级电容器的出色电化学性能。此外，我还探索了硫化物在能量储能和转化中的潜力，构建了双重调制的NICO2O4@NICO2S4异质结构，并在CUCO2S4空心纳米结构中掺入硫空位以实现增强的电化学性能。此外，我们已经探索了等离子无定形MOO3-X纳米模子/G-C3N4纳米片的界面耦合工程，用于光催化水分分裂和光热转化，从而开发出具有出色的电化学性能的高度活性光催化剂。总体而言，我们的研究表明，MOF衍生的材料，硫化物及其异质结构在储能和转换应用中具有巨大的潜力，并在著名的期刊上出版物（例如储能材料，碳能，碳能，先进的能源材料和小型）中的出版物。
