Special Issue Information

Dear Colleagues,

The transition toward a sustainable future requires innovative solutions across all technological sectors, with materials and surface science playing a decisive role. Material surfaces, acting as both functional and protective layers, are not only essential for enhancing material performance but also serve as catalysts for change by enabling greener technologies, extending product lifetimes, enhancing energy production, and minimizing environmental impact.

This Special Issue, entitled “The Research of Change: Catalysts for a Sustainable Future,” aims to highlight recent advances in catalyst research that drive sustainable transformation. We welcome original Articles, Reviews, and Communications, focusing on coatings and surface properties that address current environmental, industrial, and societal challenges.

Topics of interest include, but are not limited to, the following:

  • Development of eco-friendly, non-toxic, and biodegradable catalysts.
  • Photocatalytic and functional catalysts for environmental remediation and clean energy.
  • Durable, corrosion-resistant, and wear-resistant coatings that extend catalysts' life cycles.
  • Nanostructured, smart, and multifunctional catalysts supporting sustainable applications.
  • Recycling, circular economy, and life cycle assessment in catalyst technology.
  • Advanced characterization and modeling methods for understanding sustainable performance.

Magnesium hydride (MgH2) is a promising solid-state hydrogen storage material owing to its high hydrogen capacity and low cost, yet its practical application is limited by sluggish kinetics, high operating temperatures, and poor cycling stability. Among various catalytic approaches, Fe-based catalysts have emerged as attractive candidates due to their abundance, compositional tunability, and effective promotion of hydrogen sorption reactions in MgH2 systems. This review critically summarizes recent progress in Fe-based catalysts for MgH2 hydrogen storage, encompassing elemental Fe, iron oxides, Fe-based alloys, and advanced composite catalysts with nanostructured and multicomponent architectures. Mechanistic insights into catalytic enhancement are discussed, with particular emphasis on interfacial electron transfer, catalytic phase evolution, hydrogen diffusion pathways, and synergistic effects between Fe-containing species and MgH2, supported by experimental and theoretical studies. In addition to catalytic activity, key stability challenges—including catalyst agglomeration, phase segregation, interfacial degradation, and performance decay during cycling—are analyzed in relation to structural evolution and kinetic–thermodynamic trade-offs. Finally, a roadmap for the scalable design of Fe-based catalysts is proposed, highlighting rational catalyst selection, interface engineering, and compatibility with large-scale synthesis. This review aims to bridge fundamental mechanisms with practical design considerations for developing durable and high-performance MgH2-based hydrogen storage materials. Full article
