Conclusions
α-MoO3 nanorods were synthesized by hydrothermal
method, then BiVO4 nanoparticles were grown on α-MoO3
nanorods by metal organic decomposition method to
construct a n-n heterostructure composite. The as-fabricated
sensor based on 16Mo/Bi composite exhibits the highest
response (64.5), better selectivity and rapid response (15 s) to
20 ppm TEA at 125 ℃ . The existence of n-n heterojunction
MoO3-BiVO4 is considered to be mainly responsible for the
enhanced gas sensing performance of the composite.
Considering the simple synthesis process of MoO3/BiVO4 and
excellent gas sensing properties, the composite will be
promising candidate for TEA sensor applications.
