Exploring how catalysis science is revolutionizing clean energy, environmental protection, and sustainable manufacturing in the United States.
In the intricate dance of chemical reactions that create everything from life-saving pharmaceuticals to the fuels that power our world, there exists a silent partner—a master manipulator that works behind the scenes to make reactions faster, more efficient, and more selective.
of all commercially produced chemical processes involve catalysts 8
Major challenges catalysis addresses: clean energy, environmental protection, and sustainable manufacturing
Revolutionary approaches: microwave catalysis and computational catalysis
This partner is a catalyst, and the science of harnessing its power—catalysis—represents one of the most transformative fields in modern chemistry. In the United States, researchers are pushing the boundaries of this field to tackle some of society's most pressing challenges: clean energy production, environmental protection, and sustainable manufacturing.
Catalysts are the unsung heroes of modern industry, involved in an estimated 90% of all commercially produced chemical processes 8 . From the catalytic converter in your car that transforms harmful exhaust into less toxic gases to the massive industrial processes that create fertilizer to feed the world, catalysis touches nearly every aspect of our daily lives 5 8 . Today, American scientists are leading a revolution in catalysis science, developing innovative approaches that could wean our society off fossil fuels, capture and utilize waste carbon, and create a more sustainable chemical industry.
At its simplest, catalysis is the process of increasing the rate of a chemical reaction without itself being consumed in the process 8 .
Imagine a catalyst as a clever matchmaker that brings reactant molecules together in just the right way to make them more likely to form new products, then steps aside unchanged, ready to perform the same service again and again.
Catalysts work by providing an alternative pathway for a reaction to occur—one with a lower activation energy than the non-catalyzed route 8 . Activation energy is the energy barrier that must be overcome for reactants to transform into products.
A key principle that distinguishes true catalysts is that they do not change the equilibrium of a reaction—they only speed up how quickly equilibrium is reached 8 .
Exist in a different phase from the reactants (typically solids interacting with liquid or gaseous reactants) 8 . Examples include the platinum in automotive catalytic converters and zeolites used in petroleum refining.
Exist in the same phase as the reactants (typically dissolved in liquid reaction mixtures) 3 . These often offer higher selectivity but can be more difficult to separate and recycle.
Enzymes and other biological catalysts that drive the countless chemical reactions sustaining life 8 . These are increasingly being harnessed for industrial processes due to their extraordinary specificity and mild operating conditions.
By lowering the activation energy barrier, catalysts enable reactions to proceed faster, at lower temperatures, or with less energy input—all of which translate to significant energy savings and reduced environmental impact in industrial processes.
American institutions are at the forefront of catalytic research, exploring everything from traditional thermal processes to innovative approaches that leverage alternative energy sources.
At West Virginia University, researchers led by Professor Jianli Hu are pioneering microwave catalysis for natural gas conversion 7 .
Unlike conventional heating methods that warm the entire reactor, microwave energy selectively targets the catalyst material, creating "hot spots" at the molecular level that can drive reactions more efficiently at lower overall temperatures.
At Argonne National Laboratory, researchers are using one of the world's fastest supercomputers, Aurora, to accelerate the design of new catalysts for clean energy production 5 .
"The promise of these computers is that you can carry out either very large simulations or a very large number of smaller simulations that were not feasible on previous supercomputers," explains Argonne computational chemist David Bross 5 .
One remarkable project focuses on developing "metal-embedded carbon-based catalytic membranes for co-production of ammonia and ethylene" 7 . This innovative approach simultaneously activates two notoriously stable molecules—methane (CH₄) and nitrogen (N₂)—to produce two valuable chemicals in a single, integrated process.
The potential applications for distributed, modular chemical production could revolutionize how we utilize natural gas resources, particularly those that are currently flared due to transportation challenges.
Researchers identify promising catalytic systems based on theoretical considerations and previous experimental work, focusing particularly on heterogeneous catalysts relevant to clean energy applications.
The team employs exascale-ready software tools specially developed to run on Aurora supercomputer. These tools implement novel approaches to rapidly explore molecular energy landscapes of gas-solid surface interactions.
The software uses fundamental quantum mechanics—specifically solving approximations of the Schrödinger equation—to model how reactant molecules interact with catalyst surfaces at the atomic level.
By calculating the energy changes as molecules approach, adsorb, dissociate, and form new bonds on catalyst surfaces, the software identifies the most probable reaction pathways and determines the rate-limiting steps.
The computational results guide researchers in suggesting atomic-level modifications to improve catalyst performance, such as adjusting the composition or structure of active sites.
While specific numerical results from the Aurora supercomputer are not provided in the search results, the overall outcomes and implications of this research are profound 5 :

Catalysis science represents one of the most powerful levers we have for building a more sustainable technological future.
From the supercomputers of Argonne National Laboratory to the microwave reactors of West Virginia University, American researchers are advancing this field in ways that were scarcely imaginable just a decade ago 5 7 .
The quiet revolution in catalysis is not merely about making chemical processes faster or more efficient—it's about reimagining the very foundations of our chemical industry and energy infrastructure. By learning to manipulate matter at the atomic and molecular level, catalysis scientists are developing the tools we need to address climate change, reduce pollution, and create a more sustainable relationship with our planet's resources.
As Bert Weckhuysen, Editor-in-Chief of Catalysis Science & Technology, oversees the publication of cutting-edge research from across the field, and as DOE program managers like Viviane Schwartz and Chris Bradley steward public investment in fundamental catalytic science, we stand at the threshold of a new era in molecular engineering 1 3 . The catalysts being developed in American laboratories today may well power the clean technologies of tomorrow, proving that sometimes the smallest things—even atoms and molecules—can generate the biggest changes.
