Oxygen vacancy engineering via Mo doping in NiO nanofibers for selective trace xylene detection
Puntos clave
This research aims to enhance xylene detection sensitivity in nanofibers through molybdenum doping.
Fabrication of Mo-NiO nanofibers
Incorporation of 12.5 at% Mo
Evaluation of xylene detection performance at ppb levels
Mo doping promotes formation of oxygen vacancies
Increased reactive sites lead to improved selectivity for xylene
Achieves detection of xylene at parts per billion (ppb) levels
Resumen
Mo doping promotes oxygen vacancy formation and increases reactive sites in Mo-NiO nanofibers, enabling a 12.5 at% Mo-NiO sensor to detect ppb-level xylene with high selectivity.
