A catalyst increases the rate of a reaction but it is not used up in the reaction. If a catalyst is present, the reacting particles can collide more successfully with less energy and so the reaction ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

A catalyst alters the rate of a reaction, allowing it to be done at a lower temperature. Catalysts are therefore used in the chemical industry to make manufacturing processes more economical. Some ...

A new study examines an aspect of photocatalysis that normally does not get much recognition: recyclability. In chemistry, in order to achieve efficiency of any chemical reaction, a catalyst is added ...
