Growth of MWCNTs with composite catalyst: synergistic enhancement of field emission and gas sensing properties at room temperature
Source abstract
Abstract
Multi-walled carbon nanotubes (MWCNTs) were grown on a silicon (Si) substrate by using the low-pressure chemical vapor deposition (LPCVD) technique, where iron (Fe) and aluminum (Al) colloidal solutions act as catalysts. In this work, we demonstrate the growth of MWCNTs on different concentrations of Fe in Fe/Al composite catalysts. The as-prepared various concentrations solutions were coated on Si substrate through spin coating technique with 750 rpm. The goal of Fe in composite catalysts is to have high carbon solubility and diffusion rate, and Al utilization can change the temperature of catalyst activity and increase carbon yields. The growth temperature of MWCNTs was maintained at 700 ℃. The source gas was acetylene (C2H2), along with hydrogen (H2) as a carrier gas. The growth time of MWCNTs was 25 min. Surface morphology and structural analysis were explored using field emission scanning electron microscopy (FESEM) and Raman spectroscopy respectively and it was determined that generated CNTs are MWCNTs. The diameter distribution and crystalline nature of as generated MWCNTs were studied using XRD. The effect of field emission and gas sensing on as-prepared different MWCNTs were investigated. A field emission study revealed that a higher current density (4.068 mA/cm2 at 2.668 V/µm) was observed by Fe0.025 M/Al0.100 M/MWCNTs at a low turn-on voltage (0.89 V/µm) with good stability. In addition to this, a gas sensing study revealed that the as-prepared MWCNTs are sensitive toward NH3. Excellent resistance variation was observed by Fe0.100 M/Al0.100 M/MWCNTs sample which leads to a good sensor response.
