Abstract

Nanosize homogenous rod-like tungsten bronze Cs x WO 3 with excellent NIR shielding ability was successfully synthesized by a novel and facile water controlled-release solvothermal process (WCRSP).

Graphene/MxWO3 (M=Na, K) nanohybrids with excellent electrical properties

“…Recently, much attentions have been paid to the low-temperature solution-based synthesis of mixed valence state tungsten based nanoparticles. In our previous work, several functional materials, including tungsten bronzes nanoparticles, which showed excellent NIR shielding properties [19][20][21][22], were successfully obtained by an environmental friendly solvothermal based method [23,24] Na x WO 3 and K x WO 3 with typical tungsten bronze structure were successfully synthesized by the reduction of tungstate ion with borohydride in aqueous solutions, followed by crystallization in H 2 atmospheres. The products showed excellent conductivity, visible light transparency and near-infrared shielding characteristics, implying these materials might be the potential candidates for the transparent conductive substances [21].…”

“…It is difficult to fabricate large quantities of nanostructured WO3 with low-cost production. Therefore, fabrication methods of nanostructured WO3 have been demanded to replace the methods as mentioned.Recently, Chongshen Guo et al synthesized Csdope WO3 nanorods by solvothermal process utilizing WCl6 ethanol solution at low temperature [9]. This solvothermal method has great advantage for mass production with low-cost due to its low temperature simple process.…”
