The development of nanostructured photocatalytic additives and coatings offers opportunities to solve environmental issues such as clean air, pollutant degradation and providing a clean and sustainable environment via environmental remediation, CO2 photoreduction to fuels, water splitting, H2 production, bacterial and viral disinfection and suitable organic syntheses. 

Of the many semiconductor heterogeneous photocatalysts, titanium dioxide (TiO2) is the most widely used due to its photostability, intrinsic electronic and surface properties, non-toxicity, cost-effectiveness, and environmental friendliness. However TiO2 photocatalysis suffers from several drawback. leading to the development of other materials such as nanoscale zinc oxide, carbon nitride g-C3N4, metal-organic framework (MOF) compounds., graphene-based photocatalysts, BiOCl, black phosphorus. ZnFe2O4, all of which are covered in this report. 

Applications of photocatalytic materials and coatings include: 

  • Self-sterilising, long-lasting clear coatings that kill viruses and bacteria for application in the home, corporate offices, restaurants and bars, healthcare facilities, industrial workplaces, hospitality and retail stores.
  • Degradation of pollutants and maintaining air quality. 
  • Self-cleaning architectural glass.
  • Processes for treating industrial emissions. 
  • Self-cleaning automotive glass.
  • Roof coatings to reduce pollution through the degradation of sulfur and nitrogen oxides.
  • Road and tunnel coatings.
  • Medical (self-disinfecting coatings)
  • Self-cleaning exterior paints
  • Coatings for the elimination of VOCs and odours in public spaces.
  • Water purification
  • Air purification (indoor)
  • Self-cleaning solar cell coatings.

 

Applications make use of the self-cleaning, anti-fogging, anti-microbial or water cleaving properties. In indoor environments, most surfaces, e.g. ceramic tiles, windows glass or paper, are gradually covered with organic matter such as oils, dirt, and smoke residue and become fouled. Use of photocatalytic coatings that are activated under visible light irradiation can address these issues.  Companies are now actively seeking solutions that kill bacteria using light sources commonly present in homes (near UV and visible light).
