The “catalyst in the cage”

 Catalysts are involved in more than 95% of the production of chemicals, fuels, pharmaceuticals and consumer goods. They often consist of toxic elements that are difficult to remove from the final end product and usually get destroyed during that process. A solution to this is to “capture” such catalysts in cage like materials that hold the catalyst without decreasing it's activity. Afterwards, the “catalyst in the cage”, comparable to a “ship in a bottle” can be easily be separated and reused time and time again. A good catalyst is 100% efficient, creating no side products or waste.
