These nanoporous materials exhibit high surface areas, controllable morphology (nanoparticle and thin films), and tunable surface functionalities (amino group, thiol group, carboxylic group; therefore, they have been showing great potential in many chemical engineering fields. Based on the experience and capability of our laboratory, this three-years project will focus on the synthesis of novel nanoporous materials (the composition includes silica, metal oxides, and carbon) for solving energy issues of chemical engineering nowadays: biomass conversion and CO2 capture. In the application of membrane separation, we will design and synthesize microporous nanoparticles (i.e., metal-organic frameworks (MOFs) and zeolitic imidazole frameworks (ZIFs)) with controllable particle size and functionality. The advantage of our new approach is the synthetic process will be conducted in aqueous solution so that the synthesized MOFs nanoparticles can be homogeneously mixed in organic polymer solution to prepare mixed matrix membranes (MMMs). The fabricated MMMs will be used in the pervaporation of the mixture of water/ethanol for enhanced selectivity and flux. In the application of biomass conversion, we will continue the biomass experiments developed in our group (i.e., cellulose-to-5-hydroxymethylfurfural (HMF) conversion). In particular, we will focus on the production of dimethylfuran (DMF) and furandicarboxylic acid (FDCA) from HMF by using our newly synthesized nanoporous-based solid catalysts. In addition, we will also attempt the so-called 3rd-generation biofuel (i.e., using microalgae as the biomass source). A series of new functional nanoporous-based solid catalysts will be synthesized and used as both microalgae harvester and catalyst for a one-pot microalgae harvesting, cell wall-extraction, and transesterification process. In the application of CO2 capture, we plan to synthesize a hierarchical porous nitrogen-doped carbon material (containing all micropore, mesopores, and macropore). The macropores in the material would increase the access of CO2 gas molecules, and the micro/mesopores in the material would increase the adsorption of CO2.微孔洞材料(有機金屬骨架)中孔洞材料巨孔洞材料薄膜分離生質能源CO2捕捉。Microporous materials (metal-organic frameworks)mesoporous materialsmacroporous materialsmembrane separationbiomass conversionCO2 capture.
