Co3(PO4)2 Nanoparticles Embedded in Nitrogen-Doped Carbon as an Advanced Electrocatalyst for OER in Alkaline Solution
Catalysis Letters - Tập 148 - Trang 214-219 - 2017
The advanced oxygen evolution catalysts in alkaline solution play a growing role in alternative energy devices due to the need for clean and sustainable energy. In this paper, we report the cobalt phosphate nanoparticles embedded in N-doped carbon (Co3(PO4)2@N-C) using N,N′-piperazinebis (methylene-phosphonic acid) as both phosphate and carbon sources by two-step, hydrothermal method. The prepared...... hiện toàn bộ
Theoretical and Experimental Studies of CoGa Catalysts for the Hydrogenation of CO2 to Methanol
Catalysis Letters - Tập 148 - Trang 3583-3591 - 2018
Methanol is an important chemical compound which is used both as a fuel and as a platform molecule in chemical production. Synthesizing methanol, as well as dimethyl ether, directly from carbon dioxide and hydrogen produced using renewable electricity would be a major step forward in enabling an environmentally sustainable economy. We utilize density functional theory combined with microkinetic mo...... hiện toàn bộ

Fabrication and Characterization of Controlled-Morphology Self-Supported Fe/Co Layered Double Hydroxides as Catalysts for the Oxygen Evolution Reaction
Catalysis Letters - Tập 151 - Trang 507-516 - 2020
Electrochemical water splitting is a promising method of hydrogen production that involves two half reactions, namely the fast hydrogen evolution reaction and the slow oxygen evolution reaction (OER). The latter reaction can be accelerated by electrocatalysts, which reduce its overpotential to improve energy conversion efficiency. Herein, Fe-doped Co layered double hydroxides on 3D Ni foam (CoxFey...... hiện toàn bộ
Polyaniline Salts and Complexes as Catalyst in Bisindole Synthesis
Catalysis Letters - Tập 97 - Trang 77-81 - 2004
Polyaniline salts are prepared by doping of polyaniline base with different Bronsted acids (H2SO4, HNO3 and H3PO4), organic acid — p-toluene sulfonic acid (PTSA) and Iodine (I2). Polyaniline complexes are also prepared using Lewis acids (BF3, AlCl3 and SnCl2). Polyaniline salts and polyaniline complexes are characterized by physical, electrical and spectral methods. Polyaniline salts and polyanili...... hiện toàn bộ
Novel MgO–SnO2 Solid Superbase as a High-Efficiency Catalyst for One-Pot Solvent-Free Synthesis of Polyfunctionalized 4H-pyran Derivatives
Catalysis Letters - Tập 142 - Trang 608-614 - 2012
We report for the first time the hydrothermal synthesis of MgO–SnO2 solid superbase using P123 as template. The basicity of the materials was determined by two approaches of Hammett indicators method and temperature-programmed desorption using CO2 as adsorbate (CO2-TPD). It was found that Mg/Sn molar ratio has an effect on MgO–SnO2 basicity, and superbasicity was observed only at Mg/Sn molar ratio...... hiện toàn bộ
Framework modification of microporous silicates via gas‐phase treatment with ZrCl4
Catalysis Letters - Tập 62 - Trang 99-106 - 1999
The boron forms of the zeolite Beta (B‐Beta) and SSZ‐33 (B‐SSZ‐33) are treated with vapors of ZrCl4 in an attempt to substitute the framework boron for zirconium. The resulting materials Zr‐Beta and Zr‐SSZ‐33 are characterized by X‐ray diffraction (XRD), solid state NMR, FTIR, pyridine adsorption and Raman spectroscopies. In the case of zeolite Beta, Zr substitutes the B present in the framework n...... hiện toàn bộ
Selective Hydration of Nitriles to Amides Over Titania Supported Palladium Exchanged Vanadium Incorporated Molybdophosphoric Acid Catalysts
Catalysis Letters - Tập 146 - Trang 2025-2031 - 2016
Titania supported palladium exchanged vanadium incorporated molybdophosphoric acid (PdMPAV1) catalysts were prepared and characterized by FT-IR, X-ray diffraction and Laser Raman spectroscopy. The characterization results confirmed the presence of vanadium and palladium into the primary and secondary structure of Keggin ion of heteropoly molybdate respectively. The PdMPAV1 was dispersed on support...... hiện toàn bộ
