Summary
Chalcogenide-based materials, including sulfides, selenides, and tellurides of transition and main-group metals—have emerged as versatile platforms for catalysis and sustainable energy applications due to their unique electronic structures, tunable band gaps, high chemical stability, and abundant active sites. Their low cost and earth abundance make them promising alternatives to noble-metal catalysts for a wide range of energy-related processes.
This Special Issue aims to showcase cutting-edge research on advanced chalcogenide materials for catalysis and sustainable energy conversion, bridging fundamental materials chemistry, catalytic mechanism studies, and practical applications.
We welcome contributions addressing diverse topics including, but not limited to:
· Chalcogenide-based electrocatalysts for water splitting (HER, OER) and oxygen reduction
· Photocatalytic CO₂ reduction and solar fuel production
· Thermocatalytic syngas conversion (Fischer-Tropsch, higher alcohol synthesis) and hydrodesulfurization (HDS)
· C1 chemistry: activation and transformation of CO, CO₂, and CH₄
· Chalcogenide nanomaterials for pollutant degradation and environmental remediation
· Rational design, doping, and heterostructure engineering of chalcogenide catalysts
· Mechanistic studies using in situ/operando characterization, DFT calculations, and kinetic modeling
· Chalcogenide-based materials for energy storage (batteries, supercapacitors) and thermoelectrics
