As the severity of climate change and carbon emissions becomes a global concern, technologies to convert carbon dioxide (CO2) ...

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 ...

The reaction chamber contains a small amount of platinum as a catalyst which reacts with the hydrogen peroxide to release a much larger volume of oxygen gas into actuators in the arms. Those ...

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 ...

Inside the chamber is a catalyst ... gas into the air. "A reaction can happen without a catalyst at high temperature. For instance, burning carbon monoxide in a flame makes it possible for ...

The second catalyst, tungsten oxide on silica helps that reactive carbon atom pair up with ethylene gas which is streamed through the reaction chamber, producing propylene molecules as a result.
