Silica Hollow Spheres with Ordered and Radially Oriented Amino-Functionalized…

Using anionic surfactant as templates, ordered mesoporous silica hollow spheres (MSHSs) with radially oriented mesochannels were synthesized with the aid of ultrasonic irradiation. The product was consisted of intact and dispersed hollow spheres with the diameter mostly in the range of 100-500 nm. The hollow spheres possessed uniform shell with the thickness of 35-40 nm, and the shell with r…
