Selected Research Work
1. Water wave vibration-promoted solar evaporation
Interfacial solar evaporation holds great potential for water desalination. This work developed a novel system that had an interfacial solar evaporator integrated with an angularly vibrating cantilever beam, harnessing both solar and water wave energies when floating on water surfaces for efficient water desalination. Mechanism studies revealed that the vibrating cantilever beam promoted vapor flow and condensation on specific surfaces. This work provides new insights on advancing solar desalination with the simultaneous and rational utilization of multiple sustainable energy resources. (Nano Energy 92(2021): 106745)
2. In situ biomineralization-constructed antifouling superwetting membranes
Antifouling capability is essential for superwetting nanocomposite membranes when treating oily wastewater. This work developed a novel in situ biomineralization method to fabricate superhydrophilic and underwater superoleophobic inorganic-organic nanocomposite membranes. Superior separation and antifouling performance were achieved when treating surfactant-stabilized oil in water emulsions. (Journal of Membrane Science 622 (2021): 119030)
3. Sulfite-promoted photocatalytic degradation of organic water pollutants
Photocatalytic nanomaterials illuminated by sunlight are capable of degrading organic pollutants in wastewater through generating powerful radicals. This work for the first time discovered the unique contribution of sulfite to enhancing photodegradation efficiency. It was found that sulfite radicals were produced, via the reactions between sulfite anions and photo-induced holes/hydroxyl radicals, and degraded organic pollutants efficiently.
