Wastewater treatment

We are researching and developing sustainable adsorbent materials for the removal of contaminants from wastewater. We are also exploring the application of photocatalysts for the degradation of contaminants in waste effluents. Under this theme, we are interested in manipulating the conditions for synthesizing the adsorbents and photocatalysts in order to tailor their properties for specific applications.

Some papers published already under this theme are listed as follows.
