Description
Summary:[Display omitted] •Demonstration of monolithic nano-array catalysts featuring low catalyst usage.•Cost-effective doped Co3O4 catalyst for low temperature propane oxidation.•Controlled Ni doping leads to enhanced reaction kinetics and catalytic activity.•A redox reaction mechanism of propane oxidation as revealed by in situ spectroscopy.•Declined thermal stability of Ni-doped Co3O4 with Ni concentration due to NiO segregation. Low temperature propane oxidation has been achieved by Co3O4-based nano-array catalysts featuring low catalytic materials loading (15mg under flow rate of 150mL/min). The increased Ni doping into the Co3O4 lattice has led to 100% propane conversion at low temperature (
