In Berlin's laboratories, researchers are asking a question that could reshape how the world manufactures chemicals: What if the biggest breakthroughs in electrocatalysis come not from chasing better performance metrics, but from how we design and synthesize the materials themselves? This deceptively simple shift in thinking—led by Dr. Menezes and his Department of Materials Chemistry for Catalysis at HZB—is opening a new frontier in the race to decarbonize industry and accelerate the global transition to sustainable energy.
The challenge is urgent. As the chemical industry gears up to replace fossil fuels with green hydrogen and hydrocarbons produced through electrocatalysis, we face a critical bottleneck: electrocatalysts must be made from widely available, inexpensive materials that perform reliably, efficiently, and with precision. Yet many of today's catalysts fall short on one or more of these fronts. The question is no longer just "does it work?" but "how do we make it work better?"
The answer, according to research published by Menezes and his team in the journal Angewandte Chemie, lies in reimagining synthesis itself. A material's phase, crystallinity, defect density, oxidation state, morphology, conductivity, and local coordination environment are all determined during the synthesis process. These features then dictate how active sites form, how charges and ions move, and even how the catalyst transforms under real operating conditions. "In electrocatalysis, we often focus on activity, selectivity and durability, but these properties do not emerge by chance," explains Menezes. "They are already born during synthesis."
What makes this insight powerful is that it applies across the full range of synthetic methods—from solid-state synthesis and wet-chemical strategies to electrodeposition and interfacial growth techniques. But there's an added complexity that the HZB team highlights: in many cases, the catalyst we synthesize does not perform the reaction itself. Instead, the true active material develops in situ during operation. Understanding and controlling this transformation has become one of the central challenges of modern catalysis research.
This is where the convergence of chemistry, advanced characterization, automation, and artificial intelligence becomes transformative. Dr. Niklas Hausmann notes that new developments in in situ analytics, data-driven research, and autonomous robotics are dramatically improving our ability to predict, reproduce, and accelerate material synthesis processes. These technologies allow researchers to observe what happens to materials as they work, gather enormous datasets in real time, and use machine learning to identify patterns humans might miss. The result is a dramatic increase in throughput—more catalysts tested, understood, and optimized in less time.
The implications extend across electrochemical technologies under realistic, industrial-scale conditions. Electrolysers, CO₂ reduction reactors, and other devices that will be essential to a decarbonized economy all depend on these catalysts performing flawlessly. As synthesis evolves from a preparatory step into the central tool for targeted catalyst development, it becomes the lever for unlocking cleaner fuels and greener manufacturing at scale.
"We are entering a fascinating era in which chemistry, advanced characterization, automation and AI are converging," says Menezes. "The future of catalysis may not depend on discovering a single miracle material, but rather on learning how to systematically control matter and its evolution under working conditions, where materials chemistry will determine the future of catalysis."
