Research Interests

My research interests mainly include membrane-based gas separations and CO2 capture. Membranes technology features high intrinsic energy efficiency, low footprint and easy operation, and can be a promising alternative to conventional energy-intensive thermally-driven processes for gas separations, such as pre-combustion carbon capture combined with blue H2 production from methane reforming or coal gasification. The separation of H2 from CO2 is a critical step for this process to be economically competitive. Here, I devoted his research to rationale designing advanced polymer-based membranes for H2/CO2 separation, and have developed three methodologies: 1) Building polybenzimidazole (PBI)-based supramolecular polymer works, and carbonizing them to carbon molecular sieve membranes containing abundant sub-3.3 â„« ultramicropores to sieve H2 from CO2; 2) Introducing branched Pd nanorods with controlled aspect ratios in PBI film to achieve three-dimensional percolated Pd networks that can facilitate H2 transport at minimal loadings; 3) Developing polyamine membranes with strong chemisorption towards CO2, counterintuitively achieving high reverse selectivity against it. Besides, I also extend my research to membrane reactors containing H2-selective membranes for water-gas shift reaction and methane reforming
