Novel approach to control CdS morphology by simple microwave-solvothermal method

A simple and environmentally friendly method of preparing sulfide photocatalyst

“…Slow addition of Na 2 S (Arora et al, 1998;Reber and Meier, 1984;Shangguan and Yoshida, 2002) and bubbling H 2 S through an aqueous precursor solutions (Arora et al, 1998;Boev et al, 2006;Dag et al, 2003) are widely used. Other methods include coprecipitation (Koca and Sahin, 2002;Tsamouras et al, 1999), microwave irradiation method (He et al, 2002;Murugan et al, 2005;Zhu et al, 2002), and hydrothermal method (Wang et al, 2006;Xua et al, 2007;Yitai et al, 1995). However, for the preparation of the I-III-VI 2 /II-VI mulitcomponent system, few papers can be found in the open literature.…”

Pd and ZnAl2O4 nanoparticles prepared by microwave-solvothermal method as catalyst precursors

“…Tu and Liu [15] applied microwave techniques to the nanoscopic metal colloids synthesis, showing that PVP stabilized precious colloid metal clusters can be obtained by microwave heating with alcohol or glycol as a reductant. Recently, Komarneni [16,17] and researches from other groups [18][19][20][21] have synthesized by microwave-solvothermal processing route various types of nanophase materials (including metal nanoparticles) having controlled physical and chemical characteristics. Particularly, nanomaterials with spinel structure were also prepared in this way [22,23].…”

Swift Morphosynthesis of Hierarchical Nanostructures of CdS via Microwave-Induced Semisolvothermal Route

“…These results epitomize that complex morphology of CdS can be conveniently controlled by tuning DETA/DI volume ratio and to some extent by adjusting the reaction time. It may be noted that (i) with microwave-solvothermal approach, Murugan et al 11 could produce only simple nanostructures such as spherical cluster like nanoparticles, prickle like nanorods, and multi-armed nanorods depending upon the nature of solvents and precursors and (ii) with conventional solvothermal approach Yao et al 5 could synthesize complex and highly ordered hierarchical nanostructures of CdS such as urchin like nanoflowers, branched nanowires, and fractal nanotrees, depending upon volume ratio of DETA/DI. With microwave induced semisolvothermal route, we could quickly generate similar type of hierarchical nanostructures of CdS.…”

“…6 In the context of CdS nanoparticles, we have noted that there have been few reports on microwave-assisted aqueous synthesis 7-9 and microwave-templated synthesis. 10 Although microwave-assisted solvothermal synthesis pertaining to simple 1D nanostructures of CdS has been occasionally reported in the literature, 11 such expedient approach remained unexplored up-till now for generating hierarchical nanostructures of CdS. The purpose of the present article is to provide a comprehensive account of notable findings associated with morphosynthesis of CdS nanostructures by microwave-induced semisolvothermal route.…”
