Description

The spherical KBi(MoO4)2 nanoparticles were first prepared by solvothermal process. The crystal structure and morphology of KBi(MoO4)2 nanoparticles have been determined by x-ray diffraction (XRD), scanning electron microscopy (SEM), BET specific surface area and pore size analysis. The KBi(MoO4)2 nanoparticles are uniform spherical and crystalized in tetragonal scheelite structure with average size about 20 nm. The specific surface area of the KBi(MoO4)2 nanoparticles is 32.4 m2 g−1. The KBi(MoO4)2 nanocrystallite is an n-type semiconductor. The sensor based on KBi(MoO4)2 nanocrystallites shows gas sensing to ethanol and n-butanol with rapid response and recovery. (paper)
