Mr. Vince Aron F. Cleofe, a BS Chemical Engineering undergraduate student, was named as the Best Oral Presenter in the recently concluded 2019 4th International Conference on Composite Materials and Materials Engineering (ICCMME 2019), held at the Tokyo University of Science, Kagurazaka Campus, Tokyo, Japan, January 19-22, 2019.
His work, entitled "Highly-Organized One-Dimensional Copper-Doped Titanium Dioxide Nanotubes for Photoelectrocatalytic Degradation of Acid Orange 52," aims to solve the long-standing problem wide band gap of titanium dioxide which limits its photocatalytic application to the ultraviolet light region. This was done by modifying its electronic structure through copper doping. By doing so, the band gap of titanium dioxide was effectively narrowed, making it applicable for visible light catalytic applications. This is of particular importance for solar-mediated photoelectrocatalysis such as in the degradation of organic textile dyes which are highly-recalcitrant in nature. This has already been published in the peer-reviewed journal, Key Engineering Materials.
The study was done with his thesis mates, Ms. Rio Ysabel A. Cañal and Mr. Kristoffer Francis P. Boado, and in collaboration with Engr. Edgar Clyde R. Lopez, an PhD Chemical Engineering student, and Dr. Jem Valerie D. Perez, research adviser.
Over a hundred participants from various universities across the world joined the conference. Among the invited keynote speakers were Prof. Umemura Kazuo (Tokyo University of Science, Japan), Prof. Jong Hak Kim (Yonsei University, South Korea), and Prof. Xiaohong Zhu (Sichuan University, China). Prof. Shu Yin (Tohoku University, Japan), Assoc. Prof. Mikio Ito (Osaka University, Japan), and Dr. Seok-Keun Koh (iCube Global, Korea) were invited as plenary speakers.
