Ozone (O3), a powerful oxidant, plays a dual role in our atmosphere. While vital in the stratosphere, ground-level ozone is a significant air pollutant detrimental to human health and the environment. Effectively removing excess ozone is crucial, and catalytic decomposition stands out as a highly efficient method. Ningbo Inno Pharmchem Co., Ltd. is actively involved in developing and understanding these catalysts to provide superior air purification solutions.

The core principle of ozone decomposition catalysts is to facilitate the conversion of ozone (O3) into diatomic oxygen (O2). This process typically occurs at room temperature and requires catalysts with specific active sites that can interact with ozone molecules. The efficiency of these catalysts is often measured by their ability to achieve high ozone removal efficiency, even in the presence of other substances like water vapor, which can sometimes hinder catalytic activity.

Recent research, including studies on bimetallic Metal-Organic Frameworks (MOFs), has shed light on the intricate mechanisms at play. For instance, specific metal ions within the MOF structure, such as cobalt, act as active centers. These sites facilitate a reaction pathway where ozone molecules bind to the catalyst, undergo a transformation, and are released as oxygen. The structure of the catalyst, whether it be honeycomb, granular, or powdered, also plays a role in optimizing contact time and reducing flow resistance, thereby enhancing overall performance. Understanding the catalytic ozone destruction efficiency is paramount for selecting the right catalyst for a given application.

Factors such as humidity, temperature, and the presence of other contaminants can influence catalyst performance. However, advanced materials are being engineered to be robust against these variables. For example, catalysts designed with specific pore structures and surface chemistries can resist deactivation by water vapor. Ningbo Inno Pharmchem Co., Ltd. focuses on developing catalysts that offer not only high initial efficiency but also long-term stability, ensuring reliable air purification over extended periods. This focus on scientific understanding and material innovation is key to addressing the growing need for effective ozone control solutions.
