NiO / Sr doped Ce0.85Pr0.10 Er0.05O2-δ mesoarchitectured catalyst for partial oxidation of CH4 and anode fueled by H2

Methane partial oxidation using FeO(x)@La(0.8)Sr(0.2)FeO(3-δ) core-shell catalyst--transient pulse studies.

The chemical looping reforming (CLR) process, which utilizes a transition metal oxide based redox catalyst to partially oxidize methane to syngas, represents a potentially efficient approach for methane valorization. The CLR process inherently avoids costly cryogenic air separation by replacing gaseous oxygen with regenerable ionic oxygen (O(2-)) from the catalyst lattice. Our recent studies sh...

Oxidation of greenhouse gases, CH4 and CO, over LaMnxNi1-xO3±δ mixed oxide

The performance of LaMnxNi1-xO3±δ perovskite mixed oxides (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) which were prepared by different methods, the Pechini and sol-gel methods in the oxidation of greenhouse gases, CH4 and CO, has been investigated. All samples were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electr...

Methane Combustion and CO Oxidation on Ag-Doped LaMn0.8Cu0.2O3±δ Mixed Oxides Prepared by Pechini and Sol–Gel Methods

Transient studies of perovskite anode catalyst for a direct CH4 Solid Oxide Fuel Cell

Introduction: The direct use of CH4 as the feed to the solid oxide fuel cell (SOFC) will allow elimination of a reformer, simplifying the SOFC system and decreasing the system cost [1]. The overall reaction on the anode catalyst in the direct CH4 SOFC is the electrochemical oxidation of CH4: CH4 + 4O CO2 + 2H2O + 8e. Due to the nature of hydrocarbon reactions at high temperature and the reducin...

Synthesis of Cu Doped NiO Nanoparticles by Chemical Method

The Cu doped NiO (NiO:Cu) nanoparticles were synthesized by co-precipitation method using NiCl2.6H2O, CuCl2.2H2O for Ni and Cu sources, respectively. Sodium hydroxide has been used as a precipitator agent. Effect of Cu doping agent on the structural and optical properties of nanostructures were characterized by XRD, SEM, AFM, spectrophotometry, FTIR a...
