The global photocatalyst market is expected to grow at a CAGR of 8.83%, reaching a market size of US$6.938 billion in 2030 from US$4.545 billion in 2025.
The term photocatalyst is derived from two words: photo, which means photon, and catalyst, a substance that changes the rate of reaction to the presence of the substance. Hence, photocatalysts change the rate of a chemical reaction depending on the light. This process is given the name photocatalysis. Photocatalysis involves reaction by photonic irradiation and semiconductor support. This material has the property of getting energized by light and can support a chemical reaction.
Photocatalysts also utilize solar energy to support sustainable chemical reactions, which has further reduced fossil fuel use during industrial processes. As research and development investment continues, especially in hydrogen technologies and solar-driven applications, photocatalytic systems have become increasingly pivotal in efforts toward sustainable global energy solutions.
Scientists from Zhejiang Ocean University in China have collaborated with the University of Missouri in the United States to develop a pioneering discovery. This press release, published in the journal eScience, is based on an innovative Au/MIL-101(Fe)/BiOBr photocatalyst for the simultaneous decontamination of water pollutants. Additionally, the existence of both Cr(VI) and norfloxacin together increases the system's efficiency and shows better performance in mixed-contaminant environments.
Integrating photocatalysis with advanced oxidation processes increases efficiency in treatment, meaning faster degradation of the pollutants. The new potential opened up by novel photocatalysts that function under visible light opens up new possibilities for these systems. Solar-driven systems are also helping to promote sustainable low-energy solutions for decentralized water treatment, especially in remote locations.
By application, the construction and infrastructure industry is anticipated to be one of the fastest-growing segments in the photocatalyst market.
Construction and infrastructure are predicted to emerge as major growth factors in the photocatalyst market due to the enormous demand for green building materials and innovative solutions for air quality improvement. Construction is contributing significantly to the economy of the United States. According to data, there were 919 thousand construction enterprises in the US in 2023. Photocatalysts, titanium dioxide in particular, are added to paints, coatings, and concrete to incorporate self-cleaning properties, reducing the cost associated with these maintenance operations and enhancing aesthetic appeal through the degradation of dirt and organic matter upon exposure to sunlight.
Photocatalytic coatings also help in fighting against air pollution as they split the harmful pollutants in the air, like NOx and VOCs. These can be found naturally in urban space, and the functionality attains great regulatory pressure to improve air quality in cities, making applications of photocatalysis viable options for building facades, pavements, and roofing materials.
With further increases in urbanization, especially in developing areas, sustainably built construction with enhanced energy efficiency and low impacts on environmental resources is being integrated into the industry. Following this, total investments in commercial buildings are reported by the Government of Canada to have increased from $3,860 million in 2022 to $4,016 million in 2023. The general introduction of photocatalytic technology in smart building systems enhances the capability and sustainability of infrastructure, further fueling the market.
Asia Pacific's photocatalyst market is anticipated to experience tremendous growth due to burgeoning urbanization, rapid industrialization, and rising environmental concerns in the region.
As countries such as China, India, and Japan expand their infrastructure and construction activities, demand for innovative, sustainable building materials incorporating photocatalytic technologies is rising. Data released by the American Institute of Architects’ (AIA) Shanghai office indicate that China is expected to construct ten cities similar to New York by 2025.
Photocatalytic materials can purify the air as they decontaminate pollutants and have self-cleaning properties, elongating the lifetime of buildings. Adding to it, interest in renewable energy and sustainable activities propels investments in photocatalytic applications in water and air purifications to deal with some of the most important environmental issues. In India, the environmental technology industry includes the potentially lucrative water and wastewater management subsector. In this regard, by 2030, the amount of water required in India is expected to double over the current availability.
Governments' stricter regulations aimed at combating pollution also promote higher adoption of photocatalytic technologies. For instance, in India, in July 2024, a new metal oxide nanocomposite was designed, which aids in the photocatalytic degradation of organic pollutants such as dyes and pharmaceuticals. Hence, it can be employed as a sustainable technology for cleaning up the environment.
