Controlled synthesis of copper sulfide 3D nanoarchitectures through a facile hydrothermal route

Bismuth tungstate nano/microstructures: Controllable morphologies, growth mechanism and photocatalytic properties

“…It can be clearly seen from these two formulas that low pH value (<7) is favorable for the formation of the Bi 2 WO 6 phase in Bi(NO 3 ) 3 and Na 2 WO 4 . If the pH value is higher than 7, the newly formed Bi 2 O 2 (OH)NO 3 will react with OH − and WO 4 2− , and form the Bi 14 W 2 O 27 crystals immediately.…”

“…In recent years, the morphology and size controlled synthesis of materials have attracted much attention due to their unique chemical and physical properties that are relevant to the shape and size [1][2][3][4][5][6]. Considerable efforts have been devoted to synthesize novel nano-and microstructured materials with various morphologies, such as low-dimensional structures (e.g., rods [7], wires [8,9], belts [10], tubes [11]) and hierarchical structures (e.g., branches [12], urchins [13], hollow spheres [14,15]), for their specific properties and corresponding potential applications.…”

Controlled synthesis of hierarchical CuS architectures by a recrystallization growth process in a microemulsion system

“…However, the relatively slow growth of the recrystallization growth process may be beneficial to the formation of nanoplates in our system. In addition, other groups' methods [16,17,30,41] in synthesis of hierarchical CuS usually require high-reaction temperatures (above 100°C) in a solvothermal system. In comparison with those routes, hierarchical CuS architectures are formed more easily through the recrystallization growth process in the low temperature.…”

“…However, it is still a great challenge for controlled synthesis of hierarchical architectures via the solution phase chemical methods because the control of nucleation and growth process of nanomaterials is difficult [15]. Among the solution phase chemical methods, twophase method is a facile and effective solution phase method to synthesize hierarchical structures [16,17]. Furthermore, the two-phase method experiences a much longer and relatively slow nucleation and growth process [18].…”

“…Yan et al [16] have synthesized CuS intersectional nanoplates via a micro-interface reaction method. Cheng et al [17] have fabricated flowerlike CuS nanoarchitectures through a hydrothermal method. Although various CuS hierarchical architectures have been synthesized in different solution systems, there are very few studies on the control of growth process of hierarchical CuS architectures through a recrystallization growth process.…”
