Our group focuses on the designed synthesis of nanomaterials with engineered nanostructures (e.g. core-shell nanostructure, porous structure, 1-D nanowire and their arrays, ultrathin 2-D nanosheets), integrated functionalities (magnetic, photocatalytic, semiconducting), tailored composition, tuneable surface/interfacial properties (functional groups, stabilizer, positive/negative charges) for applications in heterogeneous catalysis and/or gas sensing nanodevices. New concepts, methods and strategies are being explored in our group by employing ATRP or RAFT polymerization techniques, supramolecular assembly, soft-templating, colloids and interface assembly, to realize a controllable, programmable and modular construction of nanostructured materials with synergistic effect at molecule-, nano-, and micro-scale, by tuning the molecule-molecule (particularly amphiphilic molecules), molecule-nanoclusters (nanocolloids), colloid-colloid interactions.
With various advanced characterization techniques, such as in situ TEM, Cryo-SEM, liquid AFM, on-line XPS, PL and in situ Raman spectroscopy, our group is committed to studying the catalytic and/or sensing mechanism and elucidating the composition-structure-performance relationship of the nanomaterials, and guiding the development of new catalytic materials and wearable e-sensing nanodevices or equipment.
Our research is relevant with polymer chemistry, colloid and interface sciences, materials sciences and catalysis.
