ARBOK TEGA-TiO₂ (TEGATIO)

Overview

Titanium dioxide is the cheapest and most widespread photocatalyst in the world, and it is held back by an engineering problem rather than a chemical one. The powder works best as a free suspension, at maximum contact area — and then has to be recovered, or it becomes the effluent's own contaminant. The industry's answer is to fix the particles to concrete, glass or ceramic, or to add a membrane capture stage. Both cut the contact area that made the suspension work.

TEGATIO holds the catalyst inside a porous macroscopic carrier instead. The carrier does not pass the reactor filter and does not leave with the treated stream. Retention stops being a process step and becomes a property of the shape.

Applications

Photocatalytic removal of organics, NOx and volatile compounds from water and air; industrial VOC abatement; any installation currently paying for an immobilisation substrate or a capture stage.

Operating Principle

The catalyst is finely distributed through a porous conductive body rather than sintered as bulk powder. The body is macroscopic: it stays in the reactor between cycles by geometry alone. No membrane capture stage is required, and the contact area lost to immobilisation on a flat substrate is not given up.

Key Parameters

| Parameter | Value |

|---|---|

| Catalyst | TiO₂, photocatalytic grade |

| Catalyst retention | inherent to the carrier form |

| Membrane capture stage | not required |

| Immobilisation substrate | not required |

Advantages

Removes the capture infrastructure rather than making it cheaper. Keeps the catalyst in the reactor instead of in the effluent. Raw materials remain the cheap ones the industry already buys — the economics come from removed infrastructure and catalyst service life.

Market Potential

Global photocatalyst market $3.8 bln in 2026, reaching $10 bln by 2035, before the separately budgeted cost of capture and immobilisation. North America at 24% of that market: about $900 mln in 2026, about $2.4 bln by 2035.
