Trisodium citrate assisted morphological evolution of α-MoO3 via a facile hydrothermal route and its application to improve the corrosion resistance of zinc coating
A facile trisodium citrate-assisted hydrothermal route was demonstrated for the synthesis of α-MoO 3 nanostructures. Trisodium citrate concentration-dependent morphological evolution of α-MoO 3 was achieved in hydrothermal process. The morphological evolution from nanorods to nanoplates was observed...
