Ozone (O3) is a powerful oxidant and a significant air pollutant, particularly at ground level, posing risks to human health and ecosystems. Its decomposition into stable oxygen (O2) is a critical process for air purification. NINGBO INNO PHARMCHEM CO.,LTD. is actively engaged in researching and developing advanced catalysts that can efficiently facilitate this decomposition, often under challenging conditions. Our focus on material chemistry and catalytic mechanisms is leading to breakthroughs in ozone removal technology.

Our work explores various classes of advanced materials, including Metal-Organic Frameworks (MOFs) and specially engineered metal oxides, such as manganese oxides. The chemical principles behind their efficacy are multifaceted. For MOFs, their highly ordered crystalline structures offer numerous active sites for ozone interaction. The choice of metal nodes and organic linkers allows for tuning of the electronic properties, enhancing catalytic activity. For manganese oxides, particularly those with introduced defects like manganese vacancies (VMn), the creation of Lewis acid-base pairs is key. These pairs help to facilitate the electron transfer required for ozone's stepwise decomposition, a process often limited by slow electron shuttling in less advanced materials.

A significant challenge in ozone decomposition catalysis is maintaining performance in humid environments. Water molecules can compete for active sites or alter reaction pathways. Our research into high humidity ozone catalyst properties is addressing this directly. By incorporating hydrophobic elements or designing structures that repel water, we ensure that our catalysts remain highly active even when exposed to moisture. This is crucial for real-world applications where pristine conditions are rare.

The development of a high-performance catalyst for efficient ozone decomposition involves understanding the complex reaction mechanisms. We employ advanced techniques such as in-situ spectroscopy and computational modeling to study how ozone interacts with the catalyst surface, identifying rate-determining steps and intermediate species. This deep chemical understanding allows us to optimize catalyst design for maximum efficiency and stability. The objective is to create materials that not only decompose ozone rapidly but also resist degradation from the ozone itself, ensuring a long service life.

Furthermore, our research often extends to creating multifunctional catalysts. While ozone decomposition is a primary goal, many of these advanced materials, particularly MOFs, also exhibit excellent capabilities for adsorbing or catalytically transforming other pollutants, such as VOCs. This dual functionality makes them highly valuable for comprehensive air purification systems. Our commitment to VOC removal MOFs complements our efforts in ozone abatement.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing the chemical sciences for environmental benefit. Our innovations in ozone decomposition catalysis are driven by a commitment to scientific rigor and a passion for creating cleaner air. By understanding and manipulating chemical reactions at the atomic level, we are developing next-generation catalysts that offer superior performance, durability, and applicability in a wide range of purification challenges.
