Figure 2From: A Facile Strategy for In Situ Core-Template-Functionalizing Siliceous Hollow Nanospheres for Guest Species EntrapmentEDX spectrum of SHNs synthesized by using PA2.5 and calcium ions with a 20 min of ageing time. The sample was thoroughly washed with DDW at 37 °C to remove the organic molecules physicosorbed on the surface of hollow spheres prior to analysis. In theinset XRD patterns of SHNs exhibiting different intensities at 22°–26°/2θ with the prolongation of ageing time are displayedBack to article page
