Kinetic modelling of temperature-programmed reduction of cobalt oxide by hydrogen

Kinetic modelling of temperature-programmed reduction of cobalt oxide by hydrogen

[Display omitted] •A 5-steps reduction mechanism for Co3O4 was proposed.•The promoter improved the reducibility of Co3O4 while it had little effect on CoO.•Reduction difficulties follow the order: Ru-Co-La/Al2O3
