These fancy scientific terms may sound alien to our ears, but in fact, photocatalyst technology has been around for the better part of the last century. What propelled photocatalyst technology into the headlines and made it a commercially viable product was a scientific breakthrough in the 1970s, courtesy of Japanese chemists Akira Fujishima and Kenichi Honda.
Since then, photocatalysis has been applied to several other industries, including environmental pollution removal, water disinfection, and creating self-sanitising building materials. While its potential benefits remain immense, photocatalysis did not reach mass adoption in mainstream markets because the traditional photocatalyst (titanium dioxide) only performs under UV light exposure, limiting its application.
So what’s changed since then and now? Well, for one, Raze entered the industry. Founded by Vincent Fong and Dr Shuyu Chen, PhD, of Hong Kong University of Science and Technology University, Raze Technology was launched in 2019 after over 10 years of research and development. And their mission? To develop a full suite of self-sanitising sprays, light-activated paints, and revolutionary air purifiers that do not require filter replacements practical enough for mass use. Since then, they have done just that, right here from their headquarters in Hong Kong and their offices in Shanghai.
Not only does Raze’s photocatalyst activate under any visible light, but it also forms a durable coating on any surface. Having passed the Toxicological Risk Assessment from SGS and other rigorous tests from FSE, CGMT, and Weipu Jishu, they are also recognised by leading hospitals across Asia in reducing cross-contamination between patients. Now, confident in bringing the benefits of photocatalysis right to your homes, Raze not only cleans your environment but does so without additional electricity, making it good for the world and great for your wallet!
