01Overview
What Ag+ Antibacterial Photocatalyst does.
Hospital- and hospitality-grade photocatalytic coating that remains active after lights out.
Standard TiO₂ photocatalysts require light photons to generate reactive oxygen species, pausing their catalytic activity at night or inside dimly lit corridors. botouseneco Ag+ Silver-Ion Antibacterial Photocatalyst solves this limitation through noble-metal surface plasmon resonance (SPR) doping. Nano-silver (Ag⁺) clusters anchored onto 5nm anatase TiO₂ crystals act as electron traps that prevent electron-hole recombination under weak indoor LED light, while continuously disrupting microbial cell membranes and catalytic odor bonds 24 hours a day.
24/7 Dark-Phase Sanitation
Continues neutralizing bacteria, mold spores, and organic odors in pitch-dark rooms and night-time cycles.
Non-Yellowing & Non-Darkening
Chelated nano-silver stabilization prevents photoreduction darkening on white latex ceilings and walls.
Mold & Mildew Resistance
Inhibits Aspergillus niger and wall mildew growth in humid hotel guestrooms and healthcare wards.

Reaction mechanism
Ag⁺ Surface Plasmon Resonance (SPR) & Dark-Phase Oligodynamic Catalysis
Under indoor light, Ag⁺ nanoparticles create a Schottky barrier on the TiO₂ crystal lattice, multiplying hydroxyl radical (•OH) yield by 2.4x compared to undoped TiO₂. In total darkness, immobilized Ag⁺ ions bind to thiol (-SH) and amino groups in bacterial cell walls and malodorous gases, providing uninterrupted sanitation and deodorization.

03Application
Low-Light & High-Humidity Zone Protocol
Specify Ag+ TiO₂ for corridors, basements, clinics, and humid climates.
In Southeast Asian, coastal, or healthcare projects where high humidity and low indoor lighting limit standard photocatalysts, Silver-Ion Antibacterial Photocatalyst Spray prevents wall mildew while maintaining high-efficiency HCHO and TVOC decomposition.
- 01
Baseline Concentration & Climate Log
Record initial HCHO/TVOC readings (mg/m³), room temperature (°C), relative humidity (% RH), and closure window (1h vs. 12h).
- 02
Substrate & Resin Identification
Identify whether off-gassing stems from urea-formaldehyde MDF/particleboard, phenolic plywood, solvent lacquers, or textile backings.
- 03
Atomization & Dosage Calculation
Calculate total surface area (m²) of panels, walls, and ceilings to determine exact liquid volume (ml/m²) and nozzle gauge (0.5mm–1.0mm).
- 04
B2B Packaging & Sample Validation
Confirm sample evaluation batch, TDS/MSDS export documentation, and commercial drum sizing (1L / 5L / 20L / 25L / 200L).
Suitable for
- Hospitals
- clinics
- humid coastal hotels

08Questions
About Ag+ Antibacterial Photocatalyst, answered.
01Will the silver ions in Silver-Ion Antibacterial Photocatalyst Spray turn white painted walls grey when exposed to sunlight?
No. Our Ag⁺ ions are coordination-stabilized within the anatase TiO₂ crystal lattice rather than suspended as free silver nitrate, preventing photoreduction staining on white walls.
