Prof. Xu graduated from Jilin University with a Bachelor's degree in Chemistry in 2001. He obtained his Ph. Degree from Changchun Institute of Applied Chemistry (CIAC) in 2006.  In 2007, he joined Peng Chen's Group at Cornell University as a postdoctoral. At Cornell University, he got interested in  single-molecule methods to study single-particle nanocatalysis with fluorescence microscopy. In 2009, he moved to UC Berkeley to study single molecule genotyping. In 2010, he went to Lawrence Berkeley National Laboratory, where he focused on single-molecule single-particle photocatalysis. In 2012, he went back to Changchun Institute of Applied Chemistry  and built his own researhc group by focusing on energy process-related basic (single-molecule single-particle nanocatalysis) and practical (functional materials for fuel cells) research.

Single-molecule and Single-particle research
最小化 最大化
    Owing to the structural dispersion, the catalytic properties of nanoparticles are challenging to characterize in ensemble-averaged measurements. The single-molecule approach enables studying the catalysis of nanoparticles at the single-particle level with real-time single-turnover resolution.We discuss the singlemolecule kinetic formulism of the Langmuir–Hinshelwood mechanism for heterogeneous catalysis, as well as of the two-pathway model for product dissociation reactions. This formulism enables the quantitative evaluation of the heterogeneous reactivity and the differential selectivity of individual nanoparticles that are usually hidden in ensemble measurements.

For the development of fuel cell industry, the most critical point is the cathode oxygen reduction reaction (ORR) due to the sluggish kinetic process.we successfully fabricated a familyof F-doped cheap carbon-based electrocatalysts (BP-F) for ORR in alkaline medium.The maximum power density of ADMFC with BP-18F as cathode outperforms the ADMFC withcommercialPt/C as cathode. Thesenovel metal-free electrocatalysts are the most promising alternatives to Pt for the application in alkalinefuel cells.

      The voltages and power densities of ADMFCs at 60oC with (square) BP-18F (3 mg/cm2) and (star) Pt/C (60 wt %, 3 mg Pt/cm2) as cathodes, respectively. Anode: Pt/C (60 wt %, 3 mg Pt/cm2) with 2 M methanol in 2 M KOH with a flow rate of 5 mL/min, cathode: dry oxygen with flow rate of 100 mL/min
