At present, the industry is in its nascent stage, with few manufacturers. Japan is expected to lead the industry, owing to the early adoption of the technology. In addition, high investment in R&D pertaining to the product coupled with several patents by the Japanese researchers are key factors contributing to the high growth.
The industry was dominated by the TiO2 photocatalysts, owing to early research on this product. However, initiatives taken by the manufacturers to develop innovative photocatalysts materials using zinc oxide (ZnO), and cadmium sulfide (CdS) is likely to challenge the existing material and open new avenues for the industry growth over the projected period.
