Abstract
Monoclinic scheelite BiVO4 nanoplates have been prepared via a facile hydrothermal method with monoethanolamine as a surfactant. The obtained BiVO4 nanoplates were characterized by XRD, SEM, Raman microscope and N2 adsorption-desorption analysis. The BiVO4 prepared with MEA is monoclinic scheelite plates which is composed of nanocrystallite with the average size of 100â¯nm. The sensors based on BiVO4 nanoplates show good sensitivity to alcohols gases, especially to n-butanol. The sensitivity to 100â¯ppm n-butanol gas is 61.6â¯at 260â¯Â°C, and the sensors exhibit low sensitivity to xylene, formaldehyde and toluene. The BiVO4 nanoplates could be a promising candidate for high selectivity and high sensitivity n-butanol gas-sening materials.
