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能量存储和转换应用的具有改进电化学性能的MOF衍生材料。通过各种合成方法，包括直接碳化，模板辅助合成和化学活化，我们制备了具有高比表面积，孔体积和电导率的MOF衍生碳基材料，这些都是提高储能器件电化学性能的关键因素。例如，我们已经使用自模板法制备了具有高N掺杂的中空有序介孔碳（HOMC）材料，其已经显示出用于超级电容器的上级电化学性能。此外，我还探索了硫化物在能量存储和转换中的潜力，构建了双调制NiCo2O4@NiCo2S4异质结构，并在CuCo 2S 4中空纳米结构中引入硫空位以实现增强的电化学性能。此外，我们还探索了等离子体非晶MoO 3-x纳米点/g-C3 N4纳米片的界面耦合工程，用于光催化水裂解和光热转换，开发具有优异电化学性能的高活性光催化剂。总的来说，我们的研究已经证明了MOF衍生材料，硫化物及其异质结构在能量存储和转换应用中的巨大潜力，并在着名期刊上发表了文章，如储能材料，碳能源，先进能源材料和小型。
