Discovering new catalysts is one of the central challenges in developing clean-energy technologies such as green hydrogen production. Yet catalyst discovery has traditionally remained confined within individual material families, limiting researchers’ ability to transfer knowledge across chemically distinct systems.
A research team led by Director HYEON Taeghwan of the Center for Nanoparticle Research within the Institute for Basic Science (IBS) has developed an artificial intelligence (AI) framework that discovers catalysts in a fundamentally new way — by combining knowledge across different catalyst families.Researchers from The University of Osaka created stable cobalt-based honeycomb structures inside a layered material and observed ferromagnetic-like ordering at low temperatures. By introducing a small amount of cobalt into NaSbO3, the team demonstrated a new platform to study Kitaev materials using abundant 3d transition metals, potentially supporting future cost-effective quantum technologies.
A new review synthesizes a decade of research into one of the most promising materials for water purification, biochar–hydrogel composites, and concludes that their effectiveness is governed by a single, critical factor: the chemistry of their surfaces. The work, led by corresponding author Dr. Dong Hee Kang at Morgan State University, provides a unified framework for understanding how these materials function and a clear roadmap for designing more robust and efficient filters to tackle global water contamination.
Biochar, a carbon-rich material made from pyrolyzed biomass, and hydrogels, water-absorbing polymer networks, are powerful on their own. When combined, they create a synergistic adsorbent with enhanced capabilities. This review analyzes the extensive body of literature to demonstrate that the true power of these composites comes from their surface functional groups—specific chemical moieties like carboxyl, hydroxyl, and amine groups that act as molecular-scale "hooks" to capture contaminants. The hydrogel matrix not only adds its own functional groups but also makes the biochar’s reactive sites more accessible, explaining why the composite consistently outperforms its individual components.
