In a monumental leap for materials science and sustainable energy, researchers at Seoul National University, in collaboration with Kookmin University and the Korea Institute of Science and Technology (KIST), have engineered a revolutionary hydrogen catalyst that may reshape the global energy landscape.

Led by Professor Jin Young Kim and detailed in the prestigious journal Energy & Environmental Science, the new core-shell nanocluster catalyst leverages ruthenium—a cost-effective alternative to platinum—to achieve unprecedented levels of efficiency and stability in hydrogen production.

Hydrogen as a Clean Energy Powerhouse

Hydrogen is hailed as the clean energy fuel of the future. Unlike fossil fuels, its combustion releases no carbon dioxide, making it a critical player in our transition toward a carbon-neutral world. But its promise has been shackled by one major hurdle: the inefficiency and cost of current electrolysis technology—until now.

Breaking Barriers with Core-Shell Nanotechnology

The team’s innovation centers around an atomic-level engineering process that forms a core-shell structure under 2 nanometers in size. By depositing ruthenium oxide on molybdenum-doped titanium dioxide and using a unique thermal treatment, they created a highly porous, stable, and high-performance nanocluster catalyst. The result: a material that outperforms traditional platinum-based systems while using just a third of the precious metal.

Record-Setting Performance

In industrial-scale testing using Anion Exchange Membrane Water Electrolysis (AEMWE), the new catalyst achieved:

  • 4.4 times higher efficiency than platinum at the same metal content
  • Record-high hydrogen evolution reaction performance
  • Lower energy requirements and higher stability under high current densities

Its advanced foam electrode design ensures optimal material delivery during electrolysis, adding yet another edge in industrial applications such as hydrogen fuel cells, power plants, and clean transportation systems.

A Step Toward a Hydrogen-Powered Future

This breakthrough is more than academic—it paves the way for commercial-scale hydrogen production with dramatically lower costs. The combination of high catalytic activity, long-term durability, and reduced reliance on expensive materials positions this core-shell nanocluster as a keystone technology for the green energy revolution.

“Despite its minuscule size, our core-shell catalyst achieves remarkable performance,” said Professor Jin Young Kim. “It marks a significant advance in nano-device fabrication and hydrogen production technologies.”

The research was supported by the National Research Foundation of Korea and is expected to accelerate real-world implementation of clean hydrogen energy solutions.

AI Tools for Chemistry: The ‘Death’ of DFT or the Beginning of a New Computational Era?

Image
For decades, Density Functional Theory (DFT) has been the workhorse of quantum chemistry and materials modeling. From predicting electronic structures to optimizing molecular geometries, DFT has powered countless breakthroughs in fields as diverse as catalysis, materials design, and condensed matter physics. But recent announcements in the scientific community have caused ripples: is DFT “dead” — or is this simply the dawn of a new computational era powered by artificial intelligence ? The Shock of Declaring a Field “Dead” The provocative statement came during the EuChemS Inorganic Chemistry Conference , where theoretical chemist Markus Reiher announced the “death of DFT.” His claim wasn’t about obsolescence in a literal sense, but about a paradigm shift: AI models can now deliver DFT-level accuracy at a fraction of the cost , fundamentally changing how chemists approach molecular modeling. This echoes previous moments in scientific history where disruptive technologi...

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...
