PbS hollow nanospheres with diameters of 80-250 nm have been synthesized by a surfactant-assisted sonochemical route from Pb(CH3COO)2, thioacetamide, and sodium dodecylbenzenesulfonate [3]. 200-400 nm hollow silica spheres with mesoporous walls were prepared by the application of ultrasound to a mixture of nonionic polyoxyethylene surfactant and tetraethylorthosilicate. The presence of surface-active agents during ultrasonic synthesis was proved to be effective because surfactants can act as soft templates as well as structure directing agents for the assembly and subsequent... 

Zhou et al. reported template-synthesized cobalt porphyrin/polypyrrole (TPPS-Co/PPy) nanocomposite and its electrocatalysis of oxygen reduction in a phosphate buffer solution (PBS) [97]. With the assistance of ultrasonication and different preparation procedures, the nanocomposite can be electrochemicaUy synthesized with uniform 2-D and 3-D nanostructures. Lines (a) and (b) of Figure 17.8 show the cyclic voltammograms of a cobalt...
