Hydrothermal synthesis of uniform WO3 submicrospheres using thiourea as an assistant agent

Novel WO3/Sb2S3 Heterojunction Photocatalyst Based on WO3 of Different Morphologies for Enhanced Efficiency in Photoelectrochemical Water Splitting

“…In one word, the crystal structure/shape/size and start crystallization temperature are eventually decided by pH value. 33 So we achieved various WO 3 nanostructures of different crystal orientation by adjusting the pH values of the precursor solutions (Figure 2d−f). Each kind of WO 3 nanostrutures represents the varied crystalline structure such as nanoplate and nanorod represent monoclinic phase while microcrystal represents hexagonal phase.…”

Flower-like and hollow sphere-like WO3 porous nanostructures: Selective synthesis and their photocatalysis property

“…Rajagopal et al synthesized the WO 3 rectangular slab, nanowire clusters, and rod-like structures by hydrothermal method using sodium tungstate alone as starting material, and sodium tungstate in presence of ferrous ammonium sulfate or cobalt chloride as structure-directing agents [30]. Su et al fabricated nearly monodisperse WO 3 submicrospheres using tungsten acid and HCl as the starting materials and thiourea as a structure-directing agent through a facile hydrothermal method [31]. Sadakane et al reported three-dimensionally ordered macroporous WO 3 prepared using monodispersed poly(methyl methacrylate) spheres as template [32].…”

Large-scale synthesis of hydrated tungsten oxide 3D architectures by a simple chemical solution route and their gas-sensing properties

“…25 Su et al fabricated nearly monodisperse tungsten trioxide submicrospheres using tungsten acid and HCl as the starting materials and thiourea as a structure-directing agent through a facile hydrothermal method. 26 Sadakane et al reported three-dimensionally ordered macroporous WO 3 prepared using monodispersed poly (methyl methacrylate) spheres as template. 27 Zhu et al successfully fabricated copper-doped tungsten oxide with photonic crystal structures by using butterfly wings as a hard-template.…”
