Zn-doped Co3O4 nanoparticles: promising room temperature sensor materials for efficient triethylamine (TEA) detection
A remarkable Zn-doped Co3O4 nanoparticle material exhibiting exceptional potential as a triethylamine (TEA) sensor was presented. Zn-doped Co3O4 nanoparticles were synthesized using a facile solvothermal method with varying concentrations of zinc dopant. The effects of Zn doping on the sensor triethylamine detection capabilities were investigated, revealing a notable enhancement in sensitivity and selectivity with a response of 2.04 at 25 °C. Furthermore, the calculated response and recovery times at the optimum temperature were 7.5 s and 27.8 s, respectively, making it an energy-efficient and quicker alternative to conventional sensors. This improvement in the sensing performance can be attributed to the optimized electronic structure and chemical properties achieved through Zn doping, which promoted the formation of abundant oxygen vacancies and improved the number of adsorption sites. These findings demonstrate that Zn-doped Co3O4 nanoparticles are promising sensor materials for efficient TEA detection, with potential applications in various industries.
期刊介绍：
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
