NSRRC Scientist Yan-Gu Lin’s Collaborative Research Highlighted as a Cover of The Journal of Physical Chemistry C
Dr. Yan-Gu Lin’s research on semiconductor materials for optoelectronics by using TLS 17B1, TLS 17C1, TLS 20A1 and TLS 24A1 was highlighted in a cover of the Journal of Physical Chemistry C. In the cover, the supreme sunlight radiated from Apollo shines equally on the golden stars (plasmonic Au), generating miracles, hopes, and happiness (represented by the photoelectrons) to the sustainable society.
A collaborative research team led by Dr. Yan-Gu Lin of the NSRRC and Academician M. C. Lin of National Yang Ming Chiao Tung University used the experimental facilities at TLS 17B1, TLS 17C1, TLS 20A1 and TLS 24A1 to conduct research on the application of hydrogenated SrTiO3/TiO2 to form robust composite photoelectrodes. The research results were published in The Journal of Physical Chemistry C, in its virtual special issue “125 Years of The Journal of Physical Chemistry”. The research was featured as the inside front cover of the issue.
Hydrogen could be potentially employed as a clean energy source in various applications, and it could be generated from water splitting using a TiO2 electrode. The development of photoelectrode materials has been considered as an important issue. The research team used the in-situ experimental techniques they have developed at the NSRRC to investigate synergistic effects of heterocoupling of perovskite-type STO on TiO2. It was found that plasmonic Au could effectively boost the photoresponse under irradiation with visible light, and apparent quantum efficiency could be achieved. Their research findings have offered a new direction for future development on composite photoelectrode materials.
