In healthcare and sterilization, hydrogen peroxide is widely used as a disinfectant and sterilizing agent in medical settings. The ability to rapidly decompose hydrogen peroxide can be leveraged in developing new sterilization technologies that are more efficient, reducing the time required to sterilize equipment and surfaces. MnO2 could be integrated into advanced sterilization systems to achieve quicker and more effective disinfection, which is particularly important in scenarios requiring rapid turnaround, such as during pandemics or in operating rooms.
