Highly Sensitive and Selective Room-Temperature H₂S Detection Using N-Doped Carbon Nanofiber/Ni-ZnO Composites.

ABSTRACT: Nitrogen-doped carbon nanofibers (NCNF) possess nanostructures with high surface area and porosity, showing excellent sensing capabilities when additionally doped with semiconducting metal oxides. However, issues related to the processability of NCNF remain a challenge in developing gas-sensing electronics. Herein, we report the use of electrospinning of polymer precursors to fabricate NCNF impregnated with uniformly distributed Ni-ZnO nanoparticles. Structural and crystallographic analyses reveal synergistic effects of NCNF with Ni-ZnO, generating multiple active sites with enhanced gas absorptivity and catalytic activity. NCNF/Ni-ZnO nanocomposites detect various gases, showing high selectivity toward H₂S at room temperature. NCNF with 15% Ni-ZnO doping show a rapid sensor res
