Sustainable nanomaterials for energy conversion and environmental remediation

This thematic issue focuses on science and engineering aspects of sustainable nanomaterials for energy conversion and environmental remediation, with emphasis on design principles, interface control, and device integration. We seek contributions that elucidate structure–property–performance relationships, especially on how to develop strategies using cutting-edge materials for charge transport, selectivity, and stability under operating conditions. Sustainability claims with quantitative evidence (e.g., durability metrics, accelerated stress testing (AST) protocols, life cycle assessment/techno-economic analysis (LCA/TEA), critical-raw-materials considerations, recyclability, and scalability) are welcome.

We welcome full research papers, letters, perspectives and reviews which include but are not limited to:

• Nanomaterials: carbon nitrides, (oxy)nitride/oxide semiconductors, MOFs/COFs, MXenes, perovskites, plasmonic and single-atom catalysts, bio-based and circular polymers, 3D-printed/porous architectures.
• Energy: electrocatalysis/photocatalysis/photoelectrochemistry for H₂, CO₂-to-X, N/O chemistries; batteries/supercapacitors.
• Environment: water purification, pollutant degradation, CO₂ capture–conversion, sensors.
• Methods: green/safe synthesis, operando/in situ spectroscopy and microscopy, DFT/ML-guided design, standardized benchmarking and reproducibility.

Submission deadline: April 30, 2026
