Co1+xAl2−xO4 (x = 0–0.2) catalysts were prepared by sol–gel method using citric acid as a chelating agent calcined at 1100 °C and then investigated for methane combustion. The catalytic activity of CoAl2O4 was significantly enhanced after Al3+ partially substituted by Co2+ cations in methane combustion. X-ray diffraction showed that all the Co1+xAl2−xO4...
