Therefore, a series of strategies have been developed for the preparation of CoAl2O4 pigment including common solid-phase method, liquid-phase and gas-phase technologies to meet the requirements of different application fields. However, the relevant applications of CoAl2O4 pigment are restricted at a certain degree due to the high cost derived from the scarcity of cobalt sources as well as the aggregation of CoAl2O4 particles during the high-temperature crystallization process. Interestingly, incorporation of stable inorganic substrates facilitates the decrease in the production cost and the control of the size and blue intensity of CoAl2O4 nanoparticles, especially incorporation of natural or waste nonmetallic mineral resources.

The results indicated that the adsorption capacity of CO on the catalyst surface was significantly influenced by the oxidation state and aggregation of Pt, with atomically dispersed Pt0 exhibiting a stronger affinity for CO. The metal-support interaction was evident in the formation of Pt-O-Ce composite bonds resulting from the incorporation of Pt ions into the CeO2 lattice, which enhanced Pt accessibility on the CeO2 surface.
