field of green energy technology, with his research focusing on two main areas: (1)the application of photocatalytic reactions in hydrogen production and (2)the development of energy storage devices, particularly supercapacitors and lithium-ion batteries. Professor Teng is a pioneer in both fields, leading innovative research. Using solar energy to convert water into solar fuel is one of the most environmentally friendly energy solutions. The reduction and oxidation half-reactions involved in the water-splitting process require energy input to overcome the thermodynamic barriers. Graphene oxide, a semiconductor composed of graphene polymers, contains only carbon, hydrogen, and oxygen and has a large surface area. Its dispersion in water can reach molecular scale, and one of its greatest advantages is that its functional groups can be modified to adjust its electronic structure and semiconductor bandgap. Professor Teng applied graphene quantum dots as photocatalysts in water-splitting reactions, demonstrating impressive efficiency and potential. This breakthrough has spurred global investment in research and development in this area. His team recently published results achieving a quantum efficiency of 20% for hydrogen production, and their work has developed a world-leading hydrogen production photocatalyst with a quantum efficiency of 30% under 420-nm light. Professor Teng also applies quantum dot technology to dye-sensitized solar cells, exploring new ideas for electron transfer that have garnered significant attention from the academic community. In recent years, he has conducted research on converting biomass into hydrogen, with outstanding results that demonstrate commercial viability.Future Prospects of ResearchSince 2017, Professor Teng has served as the project leader of the %u201cTaiwan-Germany Battery Collaboration and Advanced Green Energy Technology Promotion Office.%u201d In this role, he represents Taiwan%u2019s National Science and Technology Council (NSTC) as the academic convener, collaborating with Germany%u2019s Federal Ministry of Education and Research to lead joint battery research initiatives. By integrating Taiwan%u2019s academic community and the upstream and downstream battery industries, the project facilitates collaboration between scholars from both countries, raising Taiwan%u2019s energy storage research standards and promoting broader scientific collaboration between Taiwan and Germany.Developing high-level battery core materials is one of Taiwan%u2019s most promising research directions. The NSTC%u2019s ongoing collaboration with the German academic community is expected to elevate Taiwan%u2019s expertise in battery cell material development, enhance its international visibility, and help Taiwan penetrate the European renewable energy and electric vehicle storage markets. This effort will accelerate the development of critical energy technologies in Taiwan and has garnered significant attention in both German and Taiwanese media, with widespread reporting.Professor Teng%u2019s research on the application of photocatalyst technology to produce hydrogen fuel is globally recognized for its leading photoconversion efficiency. His work on developing high-efficiency solid-state lithium batteries has also attracted international attention, and technology transfers to industry have already been initiated. In the future, he will continue his research on carbon dioxide reduction, a highly promising field, particularly %u7b2c%u4e09%u5341%u4e00%u5c46%u6771%u5143%u734e%uff0e%u79d1%u6280%u985e%u734e%u5316%u5de5 / %u6750%u6599%u79d1%u6280
