Due to its abundance and ecological friendliness, alpha-manganese dioxide (α-MnO2) is recognized as a cost-effective bifunctional electrocatalyst for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The α-MnO2 is widely used in

γ-Al2O3 was doped with TEOS solution to obtain SiO2 content in the range of 0.6–12.4 wt%. Pt dispersion was effectively enhanced by 82 and 45 % by doping 0.6 and 1.2 wt% SiO2, and was slightly declined afterward. However, oxygen mobility as descri

Publikováno v: IOP Conference Series: Materials Science and Engineering. 778:012061
In this research, the solution combustion method was used to synthesize non-noble catalysts including copper-cerium (CuCe) and copper-cerium-iron (CuCeFe) mixed-oxides for catalytic combustion of methane. The effects of Cu contents (5, 10 and 15 wt%)

Comparison of the effects of χ phase- and Si- modified γ-Al2O3 supported Pt catalysts in CO oxidation
Autor: Piyasan Praserthdam, Nutchapon Chotigkrai, Joongjai Panpranot
Publikováno v: Catalysis Communications. 56:92-95
Effects of χ phase- and Si- modified γ-Al2O3 supported Pt catalysts on Pt dispersion and oxygen mobility of Pt/Al2O3 were investigated by CO oxidation test. Dispersion of 0.3, 0.5 and 1 wt% Pt supported on γ-Al2O3 was improved by using χ phase- a

A single-site platinum CO oxidation catalyst in zeolite KLTL: microscopic and spectroscopic determination of the locations of the platinum atoms
Autor: Cong-Yan Chen, Nigel D. Browning, Pinghong Xu, Piyasan Praserthdam, Joseph D. Kistler, Nutchapon Chotigkrai, Bruce C. Gates, Bryan Enderle
Publikováno v: Angewandte Chemie (International ed. in English). 53(34)
A stable site-isolated mononuclear platinum catalyst with a well-defined structure is presented. Platinum complexes supported in zeolite KLTL were synthesized from [Pt(NH3)4](NO3)2, oxidized at 633 K, and used to catalyze CO oxidation. IR and X-ray a
