Research

Prof. Si's work focuses on developing predictive theories of surface chemistry related to heterogeneous catalysis and photocatalysis. Past and current projects have explored topics in the fields of sustainable energy generation and conversion, functional nanomaterials, fundamental and applied heterogeneous catalysis, including CO2 reduction, water splitting, ceria catalysts for deNOx and VOCs oxidation, and new Carbon materials (Carbon nitrite, graphene). Experimental techniques include those aimed at performance assessment, kinetic analysis of chemical transformations, in operando spectroscopy, and electron microscopy. These experimental techniques are combined with first principle theoretical tools such as electronic structure calculations (DFT).

Current Projects:

  • 2016.07-2020.06, Project of National Key Research and Development Plan (2016YFC0700902-3), “Research and application of key functional decoration materials;

  • 2017.03-2020.03, the Strategic Emerging Industry Development Funds of Shenzhen, “Single Atomic Pd on C3N4/CeO2 for CO2 Hydrogenation to CO”;

  • 2015.06-2018.07, the Strategic Emerging Industry Development Funds of Shenzhen, “Pt based Bimetallic Catalysts for VOCs Oxidation”
