Figure 7From: Ordered mesoporous silica prepared by quiescent interfacial growth method - effects of reaction chemistryXRD patterns of mesoporous silica products. (a) Samples MS7 and MS12 prepared at different molar ratios of nitric acid (NA) and sulfuric acid (SA) respectively and (b) all remaining samples. Sample MS12 at 3.34 SA is not shown because no product was grown throughout the growth period.Back to article page
