“…In our previous works [33,34], it is very important for forming stable hollow spheres to ensure the quick growth of CuS nuclei by a high-interfacial reaction rate at higher reaction temperature. The formation of nanoplates becomes very difficult, probably due to quick and discontinuous growth process of CuS nuclei.…”

Nano-and micro-sized hierarchical copper monosulfide (CuS) architectures composed of nanoplates have been successfully synthesized via a recrystallization growth process in a microemulsion system. In our method, the spatial separation of two reactants and low-reaction temperature can decrease the rate of growth of the CuS nuclei, resulting in the formation of the poorly crystallized CuS aggregates in an oil-in-water (o/w) microemulsion. The hierarchical CuS nanostructures are formed easily from poorly crystallized CuS by a recrystallization growth process at a higher temperature. Furthermore, the flowerlike CuS architectures can be obtained by a kinetically controlled dissolution-recrystallization mechanism. In addition, the photocatalytic activity of the hierarchical CuS architectures has been evaluated by the degradation of methylene blue solution in the presence of hydrogen peroxide under natural light, showing that the as-prepared hierarchical CuS architectures exhibit high-photocatalytic activity for the degradation of methylene blue.

“…In previous works, we presented an interface reaction route in a microemulsion system for the preparation of CuS hollow spheres composed of nanoparticles [33,34]. In this approach, the formation of stable hollow spheres must use oil/water interface as the template at higher reaction temperature.…”

“…[109], CuS hollow spheres have been successfully synthesized through a facile microemulsion-template-interfacial-reaction route using copper naphthenate as metal precursor and thioacetamide as the source of S 2 . In this way, hollow spheres could be obtained directly since the reaction of two reactants respectively dissolved in two different phases of an O/W microemulsion only occurs at the oil/ water interface.…”

Significant progress has been made in the formulation of the functional nanomaterials with microemulsion phase. Microemulsion phase can be considered as true nanoreactors, which can be used to synthesize nanomaterials. Properties and the mechanism of nanoparticle formation with microemulsion phase are reviewed in this paper. Preparation of the various nanomaterials, such as metal nanomaterials, oxide nanomaterials, magnetic nanoparticles, inorganic and inorganic compounds nanomaterials, metallic-organic composite nanomaterials, and other composite nanomaterials, are investigated with different microemulsion phases. The possible formation mechanisms are presented with the schematic diagram. microemulsion phase, functional nanomaterials, surfactant, formation mechanism Citation: Li W, Xu P, Zhou H C, et al.

“…[12][13][14] As for the CuS semiconductor, a diverse portfolio of hollow structures have been prepared by template methods and typically physicochemical routes. [15][16][17][18][19][20][21][22][23][24][25] However the abovementioned approaches to fabrication of hollow CuS structures may increase the reaction complexity, suffer tedious synthetic procedures, and result in impurities in the products. There is no doubt that the in situ "gas-bubbles" template strategy enjoys the advantage of avoiding the template removal step in the hollow materials preparation, which appears more interesting and prospective.…”
