■研究概要
Despites the well-established three-way catalyst system for automotive emission regulation, further development of more sophisticated catalyst is still required. Recently, the research effort has been driven towards the development of a method to accelerate the catalyst evaluation. In this study, we successfully designed an operando chemiluminescence (CL) instrument for three-way catalyst screening at high sensitivity. The proof of concept of the operando CL method was established by thoroughly studying the CL behaviors of four elemental reactions, which included CO oxidation by O2/NO and C3H6 oxidation by O2/NO. The correlation of the CL intensity and the corresponding catalytic activity was examined using online gas chromatography. It was found that all the elemental reactions emitted CL. The linear correlation between the CL intensity and the reagent concentrations obtained in a steady-state measurement revealed that the CL emission is a direct product of reaction, thus the CL detection was apparently equal to detecting the reaction. The sensitivity of the CL method was estimated around 10-100 nmol. The capability of the CL method in rapid catalyst screening was confirmed by a good linear correspondence between the CL intensity and the catalytic activity in C3H6 oxidation by O2 for a series of Rh-based catalysts.

■受賞にあたっての一言
It was a great honor for me to win the award from one of the biggest conferences on catalysis. The conference provided me wonderful opportunities as well as great inspiration to meet and discuss with many reseachers from all over the world about the state-of-the-art and recent trends in different catalysis research areas. For this achievement, I would like to express my sincere gratitude to Associate Professor Toshiaki Taniike for his mentorship, enthusiastic support, constant guidance, and great encouragement during my research. I am also immensely grateful to all members in Taniike laboratory for their kindness and great help. Finally, I would like to thank my family for their love, taking care and encouraging me all the time.
