Focusing on catalytic issues in global environmental and energy development, committed to research in the field of carbon-based molecule catalytic conversion. In recent years, systematic research has been conducted on the key scientific issues in the efficient depolymerization of polymer waste and the catalytic conversion of its derived carbon-based molecules. The main academic achievements can be divided into three parts: 1) The creation of novel micro- & nano-structured catalytic materials and their microenvironmental effect modulation; 2) The structural regulation of catalytic active sites and their derived catalytic effects interpretation; 3) The development of sustainable carbon-based resource conversion systems based on the process improvement, aiming to achieve the theoretical innovation of novel catalytic materials, catalytic effect regulation, and catalytic process control for efficient refining of carbon-based resources.
