Coupling ion liquid aqueous two-phase system and the advantage of air floatation solvent flotation technology, build the enrichment ratio, good selectivity, high ion liquid aqueous two-phase gas floating solvent flotation system, will be big volume dilute solution to concentrate small unit volume, design and synthesis of target molecules has specific affinity effect of amphiphilic polymer pH sensitive/win min capture as a flotation agent, can fundamentally solve the separation flotation reagents are difficult to recycle and the problem of poor selectivity, the separation and purification of achieving high purity in the complex matrix product; Construction of functionalized ionic liquids and ionic liquid/(tungsten, molybdenum, vanadium acid salt) catalyst system, based on the ordered mesoporous materials MCM - 41, SBA - 15, silica sol, TiO2, graphene layer material of supported ionic liquid catalytic system, and applied to the fuel oxidation desulfurization, study the reaction mechanism, the catalytic system activity and structure-activity relationship of the structure, realize the selectivity ultradeep desulfurization of fuel oil; Biomass materials are directly transformed into carbon nanomaterials by one-step or multi-step method. The kinetic and thermodynamic behaviors and mechanisms of material materials into carbon nanomaterials are systematically studied to explore strategies for the regulation of carbon microstructure, conduct in-depth studies on their behaviors in energy storage and catalytic transformation, and clarify the structure-activity relationship of the process.
