Nanoparticles’ catalytic activity and intrinsic ability in generating or scavenging reactive oxygen species in general can be used to show the catalytic activity of natural enzymes. Many nanoparticles with enzyme-like activities have been found, potentially capable of being applied for commercial applications, such as in biosensors, pharmaceutical processes, and the food industry [1] . Compared with natural catalase or artificial CAT enzymes, CAT-like nanozymes have unique properties of low cost, size-dependent properties, high catalytic activity, stability, and easy surface modification[2] . One of the key oxidative threats to oxygen-tolerant organisms is hydrogen peroxide (H2O2) [3] . Virtually all organisms employ catalases and peroxidases to keep the steady-state level of endogenous H2O2 below the threshold of toxicity. Herein, MgO/Al2O3 were used as a catalase, catalyzing the decomposition of hydrogen peroxide to oxygen.MgO/Al2O3 had better stability than natural catalase when they were exposed to solutions with different pH values and temperatures. The activity of the MgO/Al2O3 was measured by UV-visible spectroscopy. The prepared Catalase were identified using FE-SEM, DRS, EDS, FT-IR, and PL.
