Did you know?

Viruses can cling to and survive on surfaces from hours to more than a week

Catalife’s highly effective technology uses natural light to neutralize viruses and bacteria – airborne and on surfaces

We are concerned
about the air we breath

Catalife introduces a breakthrough in air purification and disinfection for our health and well-being.

Technology

Catalife’s patented technology eliminates viruses, bacteria, fungi, and other pollutants (toxic chemicals and contaminants) from the air we breathe and the surfaces we touch.
The result is indoor air that is clean and pure in home, offices, vehicles, hospitals, planes, trains, buses, and more.

The Catalife material, composed of bismuth oxyhalides, highly stable semiconductors, exhibits remarkable photocatalytic activities (Photocatalysis is the acceleration of a chemical reaction by light energy, without consuming the photocatalyst).

The material is fabricated by means of a simple, cost-effective protocol that is carried out at room temperature, and without the need for harmful UV light.

The flower-like physical structure of bismuth oxyhalides forms an exceptionally large surface area for highly improved oxidation and “tailing” activity, even under dark conditions.

Extensive studies conducted by the company have demonstrated that the material’s mode of operation is fundamentally different from other commercially available photocatalysts due to its extremely efficient charge separation, which affects the amount — and lifespan — of the electron-hole pairs.

Catalife’s technologies are protected by three granted patents (WO2012066545A2, WO2015019348A2, WO2016125175A1), invented and developed by Catalife’s CTO, Hani Gnayem, PhD.

Advantages

  • Activated by visible light (daylight and regular room light)
  • Simple, low-cost synthesis process
  • Environmentally friendly
  • Noncarcinogenic
  • Patented

Capabilities

Eliminates toxins, contaminants, and any airborne viruses, germs, bacteria or fungi
Disinfects and purifies polluted or contaminated indoor air.
Quickly oxidizes ethylene to extend shelf life of fruits, vegetables, and agricultural products
Neutralizes odors

Applications

Catalife contributes to health and environmental-related applications in diverse markets and sectors. The novel, patented technology can be incorporated into air filters, fabrics, wall paints, and surface coatings — anywhere airborne contaminants affect our health — to become self-cleaning agents that continuously destroy microorganisms and neutralize contaminants.
Automotive
improves air-filter efficacy to disinfect and purify the air inside cars, taxis, and other vehicles, eliminating airborne toxins and microorganisms
Public transportation
continuously disinfects and purifies the air and neutralizes odors in airplane cabins, buses, train and subway cars, and ship cabins
Commercial
disinfects and purifies the air and neutralizes odors in office buildings, hospitals/clinics, malls, schools, warehouses for greatly improved air quality
Residential
improves efficacy of air filters to disinfect and purify the air in homes and apartments

Advantages

Activated by visible light (daylight or standard artificial room illumination).
Rapid, complete
oxidation and
germicide rate
Nontoxic: less toxic
than table salt
Environmentally
friendly, sustainable
Low cost

About

Catalife is an Israeli start-up focused on the development of a unique family of highly effective materials for the purification and contaminants elimination of air, liquids, surfaces, and fabrics.

The invention and development are based on research performed by Catalife CTO Hani Gnayem, PhD, during his studies at the Hebrew University of Jerusalem. He developed and perfected a family of bismuth-oxyhalides-based materials that exhibit remarkable photocatalytic performance under visible light conditions. The materials provide exceptionally rapid oxidation of a wide range of organic pollutants and total elimination of bacteria, fungi, and other microorganisms.

Catalife is located in the Casali Center of Applied Chemistry at the Hebrew University of Jerusalem.
