Journal ArticleDOI
Catalytic hydrolysis of hydrophobic esters on/in water by high-silica large pore zeolites
S. M. A. H. Siddiki,Takashi Toyao,Takashi Toyao,Kenichi Kon,Abeda Sultana Touchy,Ken-ichi Shimizu,Ken-ichi Shimizu +6 more
TL;DR: In this article, the authors have found that Hβ zeolite with a moderate Si/Al ratio (Si/Al = 75), Hβ-75, is an effective and reusable catalyst for hydrolysis of hydrophobic esters.
Journal ArticleDOI
Surface Oxygen Vacancy Formation Energy Calculations in 34 Orientations of β-Ga2O3 and θ-Al2O3
Yoyo Hinuma,Yoyo Hinuma,Yoyo Hinuma,Takashi Kamachi,Takashi Kamachi,Nobutsugu Hamamoto,Motoshi Takao,Takashi Toyao,Takashi Toyao,Ken-ichi Shimizu,Ken-ichi Shimizu +10 more
TL;DR: In this article, the authors propose a computational exploration of previously unknown reactive sites is a powerful strategy for the emergence of new catalytic reactions, but there are several obstacles to this approach.
Journal ArticleDOI
High-silica Hβ zeolite catalyzed methanolysis of triglycerides to form fatty acid methyl esters (FAMEs)
Md. A. R. Jamil,Abeda Sultana Touchy,Sharmin Sultana Poly,Md. Nurnobi Rashed,S. M. A. Hakim Siddiki,Takashi Toyao,Takashi Toyao,Zen Maeno,Ken-ichi Shimizu,Ken-ichi Shimizu +9 more
TL;DR: In this paper, a simple heterogeneous catalytic method for the selective transformation of triglycerides into FAMEs was presented, which was widely applicable to the transformation of various triglycerides (C4-C18 frames) into the corresponding FAME (yields of 87-93%).
Journal ArticleDOI
The Catalytic Reduction of Carboxylic Acid Derivatives and CO2 by Metal Nanoparticles on Lewis-Acidic Supports.
Takashi Toyao,Takashi Toyao,S. M. A. Hakim Siddiki,Kenichi Kon,Ken-ichi Shimizu,Ken-ichi Shimizu +5 more
TL;DR: The results of the recent studies on the direct synthesis of value-added chemicals from CO2 and carboxylic acid derivatives using supported transition-metal catalysts are summarized, and a design concept for heterogeneous catalysts that promote these processes are proposed.
Journal ArticleDOI
Reverse water-gas shift reaction over Pt/MoOx/TiO2: reverse Mars–van Krevelen mechanism via redox of supported MoOx
Shinya Mine,Taichi Yamaguchi,Kah Wei Ting,Zen Maeno,S. M. A. Hakim Siddiki,Kazumasa Oshima,Shigeo Satokawa,Ken-ichi Shimizu,Ken-ichi Shimizu,Takashi Toyao,Takashi Toyao +10 more
TL;DR: In this article, a MoOx/TiO2-supported Pt catalyst (Pt(3)/MoOx(15)/TiO 2; Pt loading = 3 wt%, MoO3 loading = 15 wt%) was proposed to promote the reverse water-gas shift (RWGS) reaction at low temperature (200-300 °C).
