Report Overview

Global Photocatalytic Coatings Market is estimated to reach at a high CAGR during the forecast period 2024-2031

Photocatalysis is the complete cycle of converting light energy (from the electrical light source or sun) into chemical energy transferred to water vapor to produce active oxygen species at the surface. Moreover, a photocatalyst coating is a coating that contains photocatalysts as ingredients. In another way, it is very similar to Photosynthesis, where light energy is transformed into chemical energy. In addition, a photocatalyst coating is energized by the presence of light. The excitation of the photocatalyst causes several reactions at the surface of the coating. This light stimulation of the photocatalyst transforms the coated surface, creating air purification and self-cleaning.

Market Dynamics

The emerging markets drive the global photocatalytic coatings growth, and huge investments in research and development are the factors responsible for this market's growth. Moreover, the rising demand for improved self-cleaning property is expected to drive the market.

In rising demand for self-cleaning products grows, partly due to consumer awareness concerning the importance of hygiene and the spread of infectious diseases. Moreover, the global market is benefiting from the increased focus on the importance of sanitary conditions and the need to disinfect household surfaces. In addition, one of the major attractions of all-purpose disinfectants is convenience, with time-strapped consumers having less and less time for household chores but eager to maintain high standards of hygiene and cleanliness.

Furthermore, innovation will prove important during the forecast period. Manufacturers keep up a constant advertising effort to promote brand image and reinforce market presence. Moreover, companies must quickly meet changing demands and shift trends through product innovation and technological savvy. Increasing manufacturing lines to include natural and eco-friendly products and packaging options is one-way companies may need to evolve. In addition, the global self-cleaning market was valued at about USD 28 billion and is expected to reach USD 38 billion with a significant CAGR during the forecast period.

Major challenges of coatings likely to drive the market growth

Most of the photocatalytic coatings present are based on TiO2, ZnO, or similar semiconductors, modified with metal-doping or nonmetals, composites, metallic nanoparticles deposition, and others to enhance the photocatalyst efficiency by increasing the range of usable wavelength, increasing the incident radiation harvesting, favoring the absorption, and increasing the interaction between pollutants & photocatalytic surface. Moreover, it focused on the durability of photocatalytic activity. Outdoor surfaces become stained with dust, dirt, and grease that hinder pollutants' adsorption on photocatalyst surfaces and subsequent degradation. The easier way to recover the surface photoactive functionality and improve the lifetime would be a feasible washing procedure.

Furthermore, the focus on multifunctional coatings with a mixture of depollution, biocide behavior, and self-cleaning properties increases demand for photocatalytic coatings. Applying these coatings on public infrastructures reduces maintenance time and cost presents a high aesthetic standard and is associated with high added value and high quality. These various properties and growing social conscience have contributed to achieving government rules to foster photocatalytic infrastructures in future urban projects.

Market Segmentation Analysis

By type, the market is segmented into titanium dioxide (TnO2), zinc oxide (ZnO), and others. By application, the market is segmented into concrete, building panels, glass, ceramics, painted surfaces, and others.

Titanium dioxide (TiO2) is widely used as a photocatalyst in many environmental and energy applications due to its low cost, 0efficient photoactivity, high stability, and safety to the environment and humans. However, its considerable bandgap energy, ca. 3.2 eV limits its absorption of solar radiation to the UV light range, accounting for only about 4.5% of the solar spectrum. Moreover, the photocatalytic activity of TiO2 is also limited by the rapid recombination of the photogenerated electron-hole pairs. When it is used in water treatment applications, TiO2 has a poor affinity toward organic pollutants, primarily hydrophobic organic contaminants. In addition, several strategies have been employed to reduce its bandgap energy, and its electron-hole recombination rates and enhance its absorption of organic pollutants.

Market Geographical Share

Asia Pacific region holds the largest market share in global Photocatalytic Coatings

APAC dominates the market for photocatalytic coatings due to the increasing demand for self-cleaning and smog-eating/air-purifying properties. China is expected to grow at a significant CAGR due to the growing penetration of the product in the construction industry. The growing pollution level in the country is expected to hinder the use of cost-effective photocatalyst-based air purification, thereby fueling the market growth over the projected period. Moreover, Japan dominated the market in 2018 in terms of revenue, accounting for USD 555 million due to the highest technology patents due to major manufacturers' presence and increased technology adoption. Also, the increasing R&D activities in the country are expected to fuel growth during the forecast period.

North America is expected to be the fastest-growing region owing to technological innovation and increasing investment in the region. Moreover, the rising awareness and low maintenance cost associated with the product are the key drivers for the region's demand for photocatalysts.  In addition, Germany was one of the leading countries for nanoparticle-based water treatment. The use of photocatalysis with nano-catalysts is a trusted method for disinfection. This is expected to contribute to the growing demand for photocatalyst coating.

Saint-Gobain

Saint-Gobain manufacture EverClean® is SHEERFILL® Architectural Membrane’s TiO2-based photocatalytic coating technology. This technology joins with nature's forces to naturally cleanse the environment to help protect our planet's future. In addition, by harnessing the sun's power and the rainwater that falls on our earth, we are installing environmentally and ecologically sound products that offer superior properties and improve our everyday living. Moreover, when UV light strikes the EverClean photocatalytic TiO2-based surface, hydroxy radicals (OH) and superoxide radicals (O2-) oxidize (decompose) organic substances. Rain or water washes them away, keeping SHEERFILL membranes dazzling white! Maintenance cleaning is virtually eliminated, as are environmentally damaging cleaning agents.

Company EverClean technology is available as a photocatalytic topcoat on the following products:

• SHEERFILL I with EverClean
• SHEERFILL II with EverClean
• SHEERFILL V with EverClean
