[1A11] Local structure of In-hydride species in zeolite and its reactivity for C₂H₆ dehydrogenation.

○Shunsaku Yasumura¹, Takashi Toyao^1,2, Zen Maeno¹, Ken-ichi Shimizu^1,2 (1. Institute for catalysis, Hokkaido University, 2. Elements Strategy Initiative for Catalysts & Batteries (ESICB), Kyoto University)

In交換CHA型ゼオライトを高温H₂雰囲気下で処理すると，ゼオライト内In ヒドリド種が生成し，エタン脱水素の活性点として働くことを見出した．In-CHAはエタン脱水素反応に優れた選択性と耐久性を示した．IR分光法，速度論的検討及び遷移状態計算から，In-CHAの活性点は[InH₂]⁺であることを明らかにした．

2:30 PM - 2:45 PM

[1A12] Highly efficient removal of ethylene at 0 ^oC over Au-Pt/zeolite

○Minyue Lin¹, Haifeng Wang¹, Tetsuya Shishido¹, Hiroki Miura¹, Masatake Haruta¹, Toru Murayama^1,2 (1. Tokyo Metropolitan University, 2. Yantai University)

Au-Pt/zeolite was used to remove ethylene at 0^oC and 80% removal efficiency was achieved at the steady state. The synergistic effect of Au-Pt alloy nanoparticles and zeolite was studied in detail.

2:45 PM - 3:00 PM

[1A13] Catalytic reduction of NO to ammonia by CO-H₂O over metal oxide supported catalysts

○Chaudhari Chaudhari Chandan¹, Keisuke Kobayashi¹, Yuichi Manaka^1,2, Tetsuya Nanba¹ (1. Fukushima Renewable Energy Inst., AIST , 2. Tokyo Inst. Tech. )

Nitrogen oxides (NO_x) are emitted from the stationary and mobile source which creates environmental issues such as acid rain and photochemical smog. Several technologies have been developed to reduce the emission of NO_x. However, these technologies are focused on the transformation of NO to less valuable N₂. On other hand, NH₃ is an important chemical which used as fertilizer and fuel. Therefore, the transformation of NO to NH₃ is a more practical way. In this study, we examined the activity of supported catalysts for catalytic reduction of NO to NH₃.
