The Photo-CREC units involve unique designs  with TiO2 photocatalysts and high quantum efficiencies. They can be used for air and water decontamination and for hydrogen production.

The Photo-CREC-II (PCW-II) Reactor is an innovative unit for hydrogen production and water decontamination with quantum yields reaching 30% levels.  

  • Two concentric tubes configure the unit: a) an opaque polyethylene outer tube, and b) a radiation transparent inner tube, with a lamp placed inside it.
  • A sealed storage tank allows the photocatalyst to be mixed and remain suspended.
  • During operation, the suspended noble metal doped photocatalyst flows in the annular space between the outer and the inner tubes.

The Photo-CREC-Air Reactor involves a novel technology for air purification:

  • The 65-liter Photo-CREC-Air unit includes the following components: a) a Venturi section with a photocatalyst immobilized on a wire mesh basket, b) a fan, c) sampling ports, d) external  lamps symmetrically placed around the reactor, and housed inside reflectors.
  • An  Automatized Spray Coating (ASC) System is used to impregnate the wire mesh of the basket with the photocatalyst. 

The Performance of the Photo-CREC-Air Reactor has been  demonstrated using model pollutants. Quantum yield efficiencies have surpassed 100% levels.
