Ni nanoparticles were deposited on mesoporous Al2O3 using TR-CVD method.
The CO oxidation experiments were conducted over the NiO/Al2O3 sample.
Annealing process at 450 °C could successfully regenerate the deactivated NiO/Al2O3 catalysts.
TR-CVD is a new strategy that can relatively simply incorporate nanoparticles into the mesoporous substrate.
