Born in southeastern China, I went to Beijing for undergraduate education after spending 18 years in Zhejiang province. At Peking university, I conducted research in the field of organometallic chemistry in Prof. Zhenfeng Xi's lab in College of Chemistry and Molecular Engineering (CCME). Hoping to achieve more in chemical research, I went abroad to the east coast of the US and became a graduate student in Chemistry Department of MIT, under the supervision of Prof. Mircea Dincᾰ. My research interests during graduate school span from electrically conductive metal-organic frameworks and porous organic polymers to electrochemcial energy storage using organic or organic/inorganic hybrid materials. After 6 years at MIT, I traveled accross the country (by driving) to the west coast and am currently a postdoctoral scholar in Prof. Zhenan Bao's lab, working on developing polymeric materials for electrochemical interphase in batteries.

Thousand-fold increase in O2 electroreduction rates with conductive MOFs.
ACS central science
2022; 8 (7): 975-982
Molecular materials must deliver high current densities to be competitive with traditional heterogeneous catalysts. Despite their high density of active sites, it has been unclear why the reported O2 reduction reaction (ORR) activity of molecularly defined conductive metal-organic frameworks (MOFs) have been very low: ca. -1 mA cm-2. Here, we use a combination of gas diffusion electrolyses and nanoelectrochemical measurements to lift multiscale O2 transport limitations and show that the intrinsic electrocatalytic ORR activity of a model 2D conductive MOF, Ni3(HITP)2, has been underestimated by at least 3 orders of magnitude. When it is supported on a gas diffusion electrode (GDE), Ni3(HITP)2 can deliver ORR activities >-150 mA cm-2 and gravimetric H2O2 electrosynthesis rates exceeding or on par with those of prior heterogeneous electrocatalysts. Enforcing the fastest accessible mass transport rates using scanning electrochemical cell microscopy revealed that Ni3(HITP)2 is capable of ORR current densities exceeding -1200 mA cm-2 and at least another 130-fold higher ORR mass activity than has been observed in GDEs. Our results directly implicate precise control over multiscale mass transport to achieve high-current-density electrocatalysis in molecular materials.
