Bulk Vanadium Oxide versus Conventional V 2 O 5 /TiO 2 : NH 3 –SCR CatalystsWorking at a Low Temperature Below 150 °C
Yusuke Inomata,Shinichi Hata,Makoto Mino,Eiji Kiyonaga,Keiichiro Morita,Kenji Hikino,Kazuhiro Yoshida,Hiroe Kubota,Takashi Toyao,Ken-ichi Shimizu,Masatake Haruta,Toru Murayama +11 more
TL;DR: In this paper, the NH3-SCR was used to treat NOx at the outlet temperature in boiler systems (100-150°C) for selective catalytic reduction of NOx.
Journal ArticleDOI
C-Methylation of Alcohols, Ketones, and Indoles with Methanol Using Heterogeneous Platinum Catalysts
S. M. A. Hakim Siddiki,Abeda Sultana Touchy,Md. A. R. Jamil,Takashi Toyao,Takashi Toyao,Ken-ichi Shimizu,Ken-ichi Shimizu +6 more
TL;DR: In this paper, a Pt-loaded carbon (Pt/C) catalytic method for the methylation of C-H bonds in alcohols, ketones, and indoles with methanol under oxidant-free conditions using a Pt/C catalyst in the presence of NaOH is reported.
Journal ArticleDOI
Isolated Indium Hydrides in CHA Zeolites: Speciation and Catalysis for Nonoxidative Dehydrogenation of Ethane.
Zen Maeno,Shunsaku Yasumura,Xiaopeng Wu,Mengwen Huang,Chong Liu,Takashi Toyao,Takashi Toyao,Ken-ichi Shimizu,Ken-ichi Shimizu +8 more
TL;DR: Kinetic and in situ spectroscopic studies as well as transition state (TS) calculations suggested that [InH2]+ ions serve as catalytic active sites for the selective dehydrogenation using In-CHA.
Journal ArticleDOI
Low-Temperature Hydrogenation of CO2 to Methanol over Heterogeneous TiO2-Supported Re Catalysts
Kah Wei Ting,Takashi Toyao,Takashi Toyao,S. M. A. Hakim Siddiki,Ken-ichi Shimizu,Ken-ichi Shimizu +5 more
TL;DR: In this paper, a low equilibrium conversion of CO2 to MeOH at high temperature is proposed. But, this method is not suitable for CO2-to-MeOH conversion.
Journal ArticleDOI
Rhenium-Loaded TiO2: A Highly Versatile and Chemoselective Catalyst for the Hydrogenation of Carboxylic Acid Derivatives and the N-Methylation of Amines Using H2 and CO2
