Top Photocatalysts Companies Transforming Clean Air, Water Treatment, and Sustainable Surface Technologies

Nanoparticles (NPs) with semiconducting properties, including charge transfer, advantageous electronic structure, and light absorption, are referred to as photocatalysts. One recognized and comprehensively studied photocatalyst is titanium dioxide (TiO2). Electron-hole pairs are formed when TiO2 absorbs light energy, and can play a role in redox reactions. The photocatalysts can break down pollutants, organic molecules, and other substances in the environment attributable to these processes.

Photocatalysts include significant structures and greater surface area to volume ratio than bulk materials, which improve their activities. Therefore, it is possible to create and fabricate materials suitable for use in novel applications by manipulating the size and form of photocatalytic materials at nanoscale range.

The growing need for clean water and air solutions is the main force behind the market’s current growth. The photocatalytic coating technology is employed in the degradation of nitrogen oxides and volatile organic compounds in building, air purification, and roads within contaminated urban centers. Moreover, photocatalytic materials are gaining popularity in the treatment of wastewater by removing heavy metals and pharmaceuticals that have been left out by conventional systems.

Fortune Business Insights estimates the market for photocatalysts to grow from USD 2,380.0 million in 2025 to USD 5,525.7 million by 2034, with a significant CAGR of 9.6% over the forecast period.

6. ISHIHARA SANGYO KAISHA, LTD.

A major producer in the photocatalysts industry, Ishihara Sangyo Kaisha, Ltd. (ISK) specializes in zinc oxide and titanium dioxide technology for self-cleaning and environmental purification. ISK created a photocatalytic powder that can be activated by visible light, with the goal of using it indoors. It is anticipated to have antiviral, antibacterial, and malodor-decomposition properties indoors.

7. Toshiba Materials Co., Ltd.

Founded in 2003, Toshiba Materials Co., Ltd. is a Japanese company that produces and sells magnetic components, specific metals, alloys, and fine ceramics. RENECAT is a high-performance, visible-light-responsive photocatalyst created by the firm to enhance indoor air quality and hygiene. It is activated by indoor lighting, such as fluorescent lamps or LEDs, in contrast to conventional titanium dioxide photocatalysts that need UV light.

8. The Chemours Company

The Chemours Company is the world’s largest producer of titanium dioxide, which makes it a major player in the photocatalysts business. Utilizing its high-performance Ti-Pure™ titanium dioxide pigments for industrial, coatings, and environmental application is the main emphasis of its advancements in this field.

9. Sharp Corporation

Sharp Corporation has built a strong foothold in the photocatalyst industry with the development of a novel tungsten oxide-based, visible light-responsive compound. Unlike traditional titanium dioxide, which requires UV light, Sharp’s approach is functional under indoor lighting (fluorescent, LED) and has shown high antiviral and antibacterial activity. By combining their photocatalytic material with platinum nanoparticles the company improved its oxidation efficiency, allowing it to break down hazardous chemicals more effectively.

10. Syensqo

With a focus on sustainability, electrification, and high-performance solutions, Syensqo, which was founded in 2023 as an independent business after being spun off from Solvay, has established itself as a significant competitor in the specialized materials market. ActizoneTM is a clever surface-disinfection technology created by Syensqo that combines quick and durable antibacterial qualities. This is consistent with the quick uptake of photocatalysts in antibacterial coating and self-cleaning applications.

Photocatalysts are Set to Redefine Global Disinfection Standards

The global market for photocatalysts is expected to benefit from increased research and development for photocatalysts as disinfectants. Photocatalysis is being researched as a possible replacement for more traditional methods, such as those that may produce potentially dangerous byproducts, as it is far more effective than other disinfection techniques, such as chlorination, at deactivating a wide variety of pathogenic microorganisms. A practical and effective method for disinfecting water and air matrices, photocatalysis can be modified for a variety of tasks. This makes it possible to employ photocatalysis in settings that would otherwise be challenging or impossible to clean.
