Direct fabrication of organic carbon coated VO2(B) (VO2(B)@C) core–shell structured nanobelts by one step hydrothermal route and its formation mechanism
3D uniform Bi2S3 chrysanthemum-like microspheres with 1D nanowire-assembly were prepared through a facile one-step hydrothermal route, using poly(vinylpyrrolidone) (PVP) as a soft template, and Bi(NO3)3 and thiourea as Bi and S sources, respectively. PVP molecules played an important role in the formation of uniform 3D Bi2S3 nanostructures. The reasonable formation mechanism of uniform chrysanthemum-shaped Bi2S3 microspheres was also proposed. Photovoltaic properties were studied preliminarily to demonstrate potential application in dye-sensitised solar cells for the replacement of scarce platinum as counter electrode.
A novel one step method to synthesize non-toxic carbon coated highly photostable core–shell magnetic and fluorescent SPIONs with long-lasting fluorescence alongside a superior magnetic resonance (MR) imaging ability.
The hollow core–shell α-Fe2O3 microspheres with improved lithium storage and gas-sensing properties have been fabricated by the template-free hydrothermal route.
