Molten salt electrochemistry is a classic topic with a history backdated to the isolation of alkaline metal by the electrolysis of molten alkaline hydroxide in 1807 (discovered by Humphry Davy), which is now shining in commercial production of metallic materials (e.g. for massive production of metallic Al with the annual yields as high as several hundred million tons). Molten salt is a unique reaction medium, which could offer unusual capability for chemical reactions, heat storage/transfer and energy storage/conversion. Therefore, molten salt electrochemistry becomes a research hotspot for controllable preparation of functional nanomaterials, carbon capture/utilization, molten salt nuclear reactor, and deep space exploration.
The general goal of our group is to develop novel technologies contributing to energy, environmental and resource sustainability by (1) developing affordable, high-efficiency and controllable preparation of materials and (2) deep understanding physicochemical properties of materials in molecular levels for diverse applications including energy storage/conversion, Fischer-Tropsch synthesis, indoor-air purification, water treatment, etc.
