Graduate Research

My research involves

• Air / moisture sensitive organic and organometallic synthesis

• Ethylene polymerization / oligomerization and ethylene / polar vinyl monomer copolymerization (NMR scale, Fisher-Potter bottle, autoclave)

• Nuclear magnetic resonance (NMR) spectroscopy:
  One-dimensional (¹H, ¹³C, ¹⁹F, ³¹P, DEPT, variable-temperature: −120~120 °C, full lineshape analysis)
  Two-dimensional (COSY, HMQC, HMBC, NOESY, HOESY, qualitative and quantitative EXSY)

• GC-MS, ESI-MS, IR, UV-Vis

• Polymer / oligomer characterization methods: GPC, DSC, NMR, GC-MS

• Homogeneous catalysis, catalyst structure – polymer property relationships

In this work, I successfully differentiated two dynamic processes in a (phosphine-sulfonate)palladium complex by delicately designed NMR experiments, particularly taking advantage of through-space ¹⁹F couplings and ¹H−¹⁹F nuclear Overhauser effects.

Since July 2014, I have been invited to peer review manuscripts for Journal of Molecular Catalysis A: Chemical (Elsevier).

Undergraduate Research

In Prof. Yan Li's group at Peking University:

• Developed a new ionic-liquid-assisted method to prepare carbon nanotube-supported platinum nanoparticles (Pt/CNT), resulted in much more uniformly dispersed nanoparticles than conventional polyol reduction method

• Increased electrocatalytic activity of Pt/CNT toward methanol oxidation by about 50%

• Applied Pt/CNT as amperometric detector of H₂O₂ (detection limit ~10^-8 mol/L)
