Research
Interest
My research focuses on the interactions between biogenic Mn oxides (MnOx) and environmentally important toxic and nutrient elements in the aquatic and soil system. Biogenic MnOx, formed from Mn(II) oxidation catalyzed by multi-copper enzymes on the bacterial cell wall, are deemed to dominant Mn oxides in nature. Due to their strong adsorption and redox activities, they impose important effects on the species, toxicities and mobility of both toxic and nutrient elements in the environment, such as nickel, zinc, copper, arsenate/arsenite, chromate/chromite, phosphate, etc. On the other hand, coexisting ions during Mn(II) oxidation will influence morphologies, structures and thus reactivity of biogenic MnOx. Traditional methods with the combination of state-of-the-art spectroscopy technologies (XAFS, STM/SEM, ATR-FTIR) will be applied.
