Nonionic templating agents

The mesoporous titania was obtained using nonionic surfactant as templating agent. Micellar solution (50 wt.%) of Ci3(EO)6-polyoxyethylene(6)... 

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... 

Size-tunable silica crosslinked micellar core-shell nanoparticles (SCMCSNs) from aPluronic nonionic surfactant (FI 27) template system with organic swelling agents such as 1,3,5-trimethylbenzene (TMB) and octanoic acid at room temperature... 

The synthesis of these ordered materials involves a structuring agent, which is a surfactant (cationic, anionic, or nonionic). The surfactant molecules form aggregates whose interactions with the silicate precursors direct the condensation toward an ordered solid containing the surfectant Removal of the surfactant by extraction or calcination leads to the mesoporous material. The surfectant plays the role of the template in the construction of the porous structure of the solid.
