Why Dispersion Instead of Powder?

Nano titanium dioxide (TiO₂) is widely recognized as the most practically valuable photocatalyst — with a bandgap of approximately 3.0–3.2 eV, UV light excitation generates highly oxidative electron-hole pairs capable of efficiently degrading organic pollutants, killing bacteria, and decomposing harmful gases.

However, the real-world photocatalytic efficiency of nano TiO₂ depends on far more than just particle size and crystal phase. Dispersion quality is the true deciding factor:

TiO₂ photocatalysis is at a critical tipping point — transitioning from academic research to large-scale industrialization. The global photocatalyst market reached $8.75 billion in 2025 and is projected to grow at a CAGR of 11.4%. Core application areas include:

1. Water Treatment

2. Air Purification

3. Self-Cleaning & Antibacterial Surfaces

4. Photocatalytic Hydrogen Production

As the classic model catalyst for photocatalytic water splitting, TiO₂'s relatively wide bandgap historically limited its visible-light utilization. However, recent breakthroughs in doping (N-doping, metal deposition) and heterostructure engineering (TiO₂/g-C₃N₄, TiO₂/MXene) have significantly enhanced its visible-light activity.

• Industrial wastewater discharge standards are continuously tightening. Recalcitrant organic compounds that resist conventional biological treatment create rigid demand for Advanced Oxidation Processes (AOPs)
• The Indoor Air Quality Management Act sets explicit VOC emission limits for new buildings and public facilities
• Korean enterprises are at the forefront of photocatalytic coating commercialization in Asia, with proven cases spanning from tunnel lighting purification to antibacterial home appliance coatings
