MXenes: Paving the Way for Sustainable Ammonia Production

MXenes Sustainable Ammonia Production

In the quest for sustainable technologies, researchers are turning their attention to MXenes, a cutting-edge class of two-dimensional materials. These carbide nitrides have shown remarkable potential to revolutionize the production of ammonia—a critical chemical for fertilizers and energy applications. By leveraging MXenes’ unique ability to fine-tune their chemical composition, scientists are exploring how to catalyze the conversion of air into ammonia in an energy-efficient and environmentally friendly way.

Reimagining Catalysis with MXenes

Ammonia production is vital for global agriculture and energy systems, but conventional methods are energy-intensive and carbon-heavy. Researchers led by Dr. Abdoulaye Djire, Dr. Perla Balbuena, and Ph.D. candidate Ray Yoo have discovered that MXenes offer a sustainable alternative. By manipulating the lattice nitrogen reactivity, these two-dimensional materials can be tailored for specific electrocatalytic applications.

“We aim to expand our understanding of how materials function as catalysts under electrocatalytic conditions,” Djire explains. This approach could enable the production of chemicals and fuels from Earth-abundant resources, moving industries closer to a sustainable future.

Why MXenes Stand Out

Unlike traditional transition metal-based catalysts, MXenes exhibit an exceptional flexibility in chemical composition. This allows scientists to precisely engineer their properties for energy applications. The research team demonstrated how nitride MXenes outperform their carbide counterparts in electrocatalytic performance.

Ph.D. student Hao-En Lai contributed with first-principles computational analyses, evaluating how energy-relevant solvents interact with MXenes’ surfaces. These insights, combined with Raman spectroscopy studies of titanium nitride, highlight the crucial role of lattice nitrogen reactivity in sustainable ammonia synthesis.

A Path Toward Greener Chemistry

The team’s findings, published in the Journal of the American Chemical Society, underscore the potential of MXenes to drive breakthroughs in renewable energy and electrocatalysis. By achieving atomistic-level understanding of the material’s structure, scientists can develop highly efficient and cost-effective catalysts for ammonia production and beyond.

“Electrochemical ammonia synthesis can be achieved through the protonation and replenishment of lattice nitrogen,” Yoo says. This reshapes our understanding of how MXenes function in electrocatalytic systems and opens new doors for sustainable technologies.

Water Simulations Under Scrutiny: Researchers Confirm Methodological Errors

Image
Accurate water simulations are vital for research in biomolecular structures, drug discovery, and materials science. But a recent study from Oak Ridge National Laboratory (ORNL) has revealed a potential pitfall in long-standing computational methods, raising concerns about the reliability of countless molecular dynamics studies. The Time Step Problem in Simulations At the heart of the issue is the “time step” used in simulations—the small intervals at which calculations are performed. Since the 1970s, scientists have used time steps of 2 femtoseconds (quadrillionths of a second) to simulate molecular motion efficiently. However, the ORNL team has shown that using this standard can introduce significant errors when modeling liquid water, potentially leading to inaccurate predictions of properties such as density, pressure, and hydration energies. “Using longer time steps is tempting because it reduces computational cost,” explained senior scientist Dilip Asthagiri. “But a...

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...
