These photocatalytic units involve unique designs  with suspended  TiO2 and high quantum efficiencies. They can be used for air and water decontamination and for hydrogen production.


Photo - CREC Water-II

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


  •      It is configured with two concentric tubes: a) a transparent inner tube and an opaque polyethylene outer tube, b) a near-UV lamp which is placed inside this inner tube.
  •      It allows a suspended noble metal doped photocatalyst to flow in the annular space between the outer and the inner tubes. The inner tube  only absorbs 5% of the near-UV light, emitted by the lamp.
  •      It is equipped with a sealed storage feed tank where the photocatalyst remains under agitation. This tank has two (2) ports for periodic liquid and gas phase sampling.

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


  •      It is configured of a 65-liter Photo-CREC-Air unit involving the following components: a) a Venturi section with a photocatalyst impregnated on a wire mesh basket, b) a fan, c) sampling ports, d) external near-UV lamps symmetrically placed around the reactor, and housed inside reflectors.
  •      It is provided with a special Automatized Spray Coating (ASC) System used for photocatalyst impregnated wire mesh preparation. 


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