Nano Photocatalyst Spray

5–10nm Visible-Light Anatase TiO₂

botouseneco Nano Photocatalyst Spray is a B2B visible-light-responsive nano-titanium dioxide (5–10nm anatase TiO₂) coating dispersion for interior walls, ceilings, and light-exposed surfaces. Applied once with a 0.5mm HVLP spray gun at 8–12 ml/m², it forms a durable, transparent catalytic film that continuously oxidizes formaldehyde, TVOC, and odors into CO₂ and H₂O under indoor LED or daylight illumination.

01Overview

What Nano Photocatalyst Spray does.

The long-term protective shield in professional multi-stage indoor air quality remediation packages.

While amino scavengers neutralize immediate source formaldehyde inside furniture, engineered panels can slowly release residual gases over multi-year cycles. botouseneco Nano Photocatalyst Spray turns room walls and ceilings into a continuous air-purifying reactor. Formulated with doped 5–10nm anatase TiO₂ nanoparticles suspended in a neutral aqueous sol, it activates under both natural window daylight and standard indoor visible LED lighting (400–600nm) without requiring harsh UV lamps.

5–10nm Particle Size

5–10nm Ultra-Fine Anatase Sol

High specific surface area nanoparticles remain stably dispersed without sedimentation or nozzle clogging.

UV + Visible Light

Indoor Visible-Light Active

Doped formulation responds to standard indoor LED lighting as well as natural window sunlight.

Continuous Action

Non-Consumptive Catalyst Film

Because TiO₂ acts as a catalyst rather than a sacrificial reactant, the cured film remains active long-term.

80–120 m² / Liter

High Coverage Yield

Low 8–12 ml/m² dosage allows a single 1L bottle to coat up to 100 m² of wall and ceiling area.

Reaction mechanism

Visible-Light Bandgap Excitation & Hydroxyl Radical (•OH) Oxidation

When photons strike the nano-TiO₂ film, electron-hole pairs are generated on the crystal surface, reacting with ambient H₂O and O₂ to produce hydroxyl radicals (•OH) and superoxide anions (O₂⁻). These high-redox-potential radicals mineralize airborne HCHO, TVOC, and organic odors into trace carbon dioxide (CO₂) and water (H₂O) without consuming the TiO₂ catalyst.

Reaction pathway

TiO₂ + hν → •OH + O₂⁻ → CO₂ + H₂O
Active chemistry
Visible-light nano-TiO₂ •OH & O₂⁻ radical mineralization
Class
Long-Term Photocatalytic Coating
Light on a TiO₂ film creates hydroxyl radicals that turn VOCs into CO₂ and H₂Oindoor LED / daylightwall5–10 nm TiO₂ film•OH•OH•OHVOC / HCHOCO₂H₂O
Visible-light photocatalysis: indoor light excites the TiO₂ film, which forms hydroxyl radicals (•OH) at the surface; they oxidise formaldehyde and VOCs to CO₂ and water while the catalyst itself is not consumed.

Particle size on a log scale. Particles far smaller than the wavelength of visible light (400–700 nm) scatter very little of it, which is why a 5–10 nm sol dries to a transparent film instead of a white haze.

03Application

Atomization Fineness & Illumination Protocol

Use a 0.5mm–0.8mm nozzle for invisible nano-film formation.

Photocatalytic efficiency is proportional to exposed surface area. Using a fine 0.5mm HVLP nozzle prevents droplet agglomeration, ensuring an optically clear film that will not whiten colored wall paint. Pair with Formaldehyde Remover inside dark, unlit cabinet interiors.

  1. 01

    Baseline Concentration & Climate Log

    Record initial HCHO/TVOC readings (mg/m³), room temperature (°C), relative humidity (% RH), and closure window (1h vs. 12h).

  2. 02

    Substrate & Resin Identification

    Identify whether off-gassing stems from urea-formaldehyde MDF/particleboard, phenolic plywood, solvent lacquers, or textile backings.

  3. 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).

  4. 04

    B2B Packaging & Sample Validation

    Confirm sample evaluation batch, TDS/MSDS export documentation, and commercial drum sizing (1L / 5L / 20L / 25L / 200L).

08Questions

About Nano Photocatalyst Spray, answered.

Ask an engineer
01Does botouseneco Nano Photocatalyst Spray work in rooms with only indoor LED lighting?

Yes. Nano Photocatalyst Spray uses a visible-light-responsive doped anatase TiO₂ dispersion that activates under standard indoor LED and fluorescent illumination as well as daylight through windows.

02Why is Nano Photocatalyst Spray paired with Formaldehyde Remover in B2B projects?

Photocatalysts require light to generate •OH radicals, so they excel on walls, ceilings, and room exteriors. Inside pitch-dark drawers, cabinet backs, and bed frames, direct chemical scavengers like Formaldehyde Remover work without light. Combining both provides 24/7 dark + light remediation.
