The phrase "active oxide" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or materials science, to describe an oxide that is reactive or has catalytic properties.
Example: "The catalyst was composed of an active oxide that significantly enhanced the reaction rate."
Alternatives: "reactive oxide" or "catalytic oxide".
CeO2 has an excellent oxygen storage and release capacity due to the ability to switch Ce4+/Ce3+, which makes CeO2 become an active oxide component of various oxidation catalysts used in diverse redox catalytic reactions [17 32].
Above 30 mol% no significant increase in activity towards oxygen evolution is gained by increasing the concentration of active oxide.
Each of these methods has a potential to design the active oxide electrocatalysts.
Moreover, the antibacterial experiments were done in the dark, so there are no active oxide, hydrogen peroxide, and super-oxide.
Low-frequency noise analysis [24] confirmed the absence of active oxide traps for most wires after the passivation step.
Peroxidases could also be used in the synthesis of fine chemicals and optically and biologically active oxide.
Gold loaded on CuO and NiO yielded the best catalysts, although there was a larger increase in catalytic activity upon gold loading for less active oxides like MgO and Y2O3.
Comparison of specific activities (calculated as amount of ethanol converted per unit weight of active oxides) at the same space velocity demonstrated the size of mixed oxides particles as the important parameter for oxidation activity: decreasing in particle size led to increased catalysts efficiency.
The measured catalytic activity of the bed material samples increased with the amount of the catalytically active oxides (CaO, MgO, Fe2O3, Al2O3).
The presence of large amounts of SiO2 and Al2O3 has prompted the use of fly ash as a support for catalytically active oxides and metals [17].
Strict control of the reaction residence time or addition of less active oxides to the catalyst (e.g., manganese, copper or cobalt oxides) is common practices to avoid this problem [16].
