These advances have led to biodegradable plastics, new pharmaceuticals, and environmentally safer fuels and fertilizers. DOE focuses on the design of new catalysts and on the use of catalysts to control chemical transformations at the molecular and sub-molecular levels.
DOE research emphasizes understanding these reactions and how to make them more efficient and targeted. This research is helping advance solar fuels , which are fuels companies make using the sun and common chemicals like carbon dioxide and nitrogen.
This research is also creating advanced methods for transforming discarded plastic into new products. Scientific terms can be confusing. DOE Explains offers straightforward explanations of key words and concepts in fundamental science. Reactions can be sped up by the addition of a catalyst, including reversible reactions involving a final equilibrium state.
Recall that for a reversible reaction, the equilibrium state is one in which the forward and reverse reaction rates are equal. In the presence of a catalyst, both the forward and reverse reaction rates will speed up equally, thereby allowing the system to reach equilibrium faster.
However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the final equilibrium position of the reaction. It simply gets it there faster. Recall that catalysts are compounds that accelerate the progress of a reaction without being consumed.

How is the Equilibrium Constant of a Reaction Determined? Even the size of the catalyst particle can change the way a reaction runs. The catalyst turns propylene into propylene oxides, which is the first step in making antifreeze and other products.
Industrial manufacturing processes for plastic and other essential items often produce nasty by-products which can pose hazards to human health and the environment. Better catalysts can help solve that problem. For example, the same silver catalyst actually produces fewer toxic by-products—making the whole reaction more environmentally friendly.
At its heart, a catalyst is a way to save energy. And applying catalysts on a grand scale could save the world a lot of energy. Three percent of all of the energy used in the U.
Catalysts are also the key to unlocking biofuels. All biomass—corn, switchgrass, trees—contains a tough compound called cellulose, which has to be broken down to make fuel. Finding the perfect catalyst to disintegrate cellulose would make biofuels cheaper and more viable as a renewable energy source.
