1. Mixed ionic-electronic conducting (MIEC) materials

Main interest is focused on the fundamentals of technological applications, such as dense ceramic membranes reactor for the effective utilization of nature gas (methane) and thermal decomposition of carbon dioxide. Essential to the research is the development of novel mixed-conducting material (with both high oxygen permeation flux and structural stability) and a fundamental understanding of the relationships between material characteristics, such as crystal structure, composition, defect chemistry and microstructure, and material properties related to diffusion of ionic and electronic species.

2. Organic-inorganic composite membranes

Research is mainly focused on the development of organic-inorganic composite membranes, which generally include two types: inorganic substrate-supported polymer composite membranes and inorganic fillers incorporated polymeric mixed matrix membranes. Materials characteristics, free volumes and interfacial morphologies of the composite membranes are tailored for efficient molecular-level separation (e.g., pervaporation, gas separation). In particular, large-scale production and industrial application of the organic-inorganic composite membranes are studied to implementing membrane technology in the fields of bio-fuels production, VOCs treatment, CO2 capture, oxygen enrichment, etc.

3. Novel membranes

Novel materials, such as graphene and metal-organic frameworks (MOFs), have attracted increasing attention in recent years. Our main works are devoted to fabricate integrated graphene-based and MOFs membranes, which serve as barriers for the selective permeation of mixture components (gas mixture or liquid mixture).

4. Porous ceramic membrane reactors

Porous ceramic membrane reactors have attracted considerable attention from both the academic and industrial communities in recent years because of they offer the capability of nano-size solid catalysts separation and gas/liquid reactants dispersion in heterogeneous catalysis. We have developed three main porous ceramic membrane reactor configurations: (a) side-stream membrane reactor, (b) submerged membrane reactor and (c) loop membrane reactor, and the major considerations for the porous ceramic membrane reactors, i.e. the application-oriented ceramic membrane design, the optimization of ceramic membrane reactor performance and the membrane fouling control are systematically studied by experimental investigation, mathematical modeling and CFD simulation.
