Photocatalytic Spray is a new technology designed to improve the air and surface quality of indoor spaces. The product combines the best of air filtration systems with a unique new active ingredient – photocatalytic efficient nanoparticles.
Photocatalytic Spray works by continuously spraying an active suspension of nano-particles into the air between surface treatments.
These incredibly small particles contain titanium dioxide, which speed up the natural mechanism of oxidation and purification in the air. Each particle works like a nanomagnetic filter, trapping and destroying odors, bacteria and other pollutants.
The product has been tested by accredited scientific institutes and has shown, through the destruction of various air, dust and other surface pollutants, to break down even the most stubborn smells and particles.
Photocatalytic Spray has been used in commercial, automotive and residential spaces to provide superior indoor air and surface quality with long-lasting protection.
The air purification properties of Photocatalytic Spray have been found to create an immediate and noticeable reduction in odors, bacteria, dust mites and other pollutants.
Furthermore, due to its eco-friendly nature combined with low cost of implementation and maintenance costs, Photocatalytic Spray offers a safe, economical and convenient way to ensure the highest quality of air and surface treatment.
The Global Photocatalytic spray market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The low cost, availability, and chemical and thermal stability of titanium dioxide (TiO2) nanoparticles in suspension make them one of the most commonly employed photocatalysts in water treatment applications.
In order to preserve a portion of the unmeted feedstock nanoparticles as the source of fine pores in the membrane microstructure, the spray parameters, such as suspension solid content, suspension feed rate, and spray distance, were optimized using an AR/H2 plasma.
When photons with energies higher than its bandgap energy (3.2 eV) are absorbed by TiO2, an electron is excited from the conduction band to the valence band, creating an electron–hole pair that further generates oxidizing radicals that can break down organic pollutants into CO2 and water.
It has been proved that a filtration membrane’s photocatalytic characteristic increases the antifouling property, which in turn improves separation performance. However, because of its large bandgap energy, TiO2 needs UV light to activate its photocatalytic property. For interior applications, this means a relatively high energy consumption and the need for modified safety precautions.
The main method used to create ceramic membranes is an asymmetric, multi-layered structure consisting of a top filtration layer, an intermediate layer to minimize pore size, and a thick porous substrate for mechanical support.
Despite ceramic membranes’ consistent performance, their use in water treatment is still restricted by their high cost, which is primarily related to the multiple steps involved in fabrication, such as shaping, sintering, and surface modification.
Furthermore, TiO2 photocatalyst applications outside of the environment are inefficient because visible light makes up over 52% of solar radiation and UV light only makes up 3%.
Therefore, creating active photocatalytic membranes in the presence of UV and visible light may result in a filtration process that is more effective and long-lasting. Because the SPS method creates oxygen vacancies and Ti3+ ions in the coating, it enables the deposition of sub-stoichiometric TiO2-x coatings.
Because the bandgap is narrowed and photogenerated electrons and holes can be excited at lower photon energies, the SPS coating exhibits photocatalytic activity under visible light.
