Engr. Edgar Clyde R. Lopez successfully defended his master's thesis entitled "Silver-doped Titanium Dioxide Nanotubes for Photoelectrocatalytic Degradation of Acid Orange 52" for the degree program of Master of Science in Chemical Engineering last November 27, 2018.
His work aimed to enhance the photoelectrocatalytic activity of titanium dioxide nanotubes in the visible light region of the solar spectrum through a one-pot silver-doping approach.
Titanium dioxide is a wide band gap photocatalyst (3.2 eV) which somehow limits its commercial potential for degrading recalcitrant compounds in wastewater. With his study, he managed to modify the structure of the nanotubes through in-situ doping with silver. This process resulted in a significant enhancement of the photocatalytic, electrocatalytic, and photoelectrocatalytic properties, in terms of the degradation of Acid Orange 52, compared to pristine TiNTs.
As of this writing, he has already presented part of his work at the International Conference on Materials Science and Engineering Technology (ICMSET 2018) held in Beijing, China last October 20-22, 2019 and has already published in the Materials Science Forum, a peer-reviewed journal.
This study was done together with his adviser, Dr. Jem Valerie D. Perez of the Nanotechnology Research Laboratory, and his co-adviser Dr. Joey D. Ocon, of the Laboratory of Electrochemical Engineering. This was funded by the Engineering Research and Development for Technology (ERDT) program of the Department of Science and Technology (DOST-SEI) and the ADMATEL Research Grant of the Philippine Council for Industry, Energy, and Emerging Research and Development for Technology (DOST-PCIEERD).
