Abstract Mesoporous silica (SBA-15 with the BJH pore size of 8 nm) containing anatase nanoparticles in two different titania contents (28 and 65 mass%), which were prepared by infiltration amorphous precursor derived from tetraisopropyl orthotitanate into pore, heat treated air to investigate structural changes (both mesostructure SBA-15 phase pore). The mesoporous particle unchanged treatment up 800 °C. at temperature higher than 1000 °C resulted collapse growth as well transformation...
Heterojunctions, particularly those involving BiOBr/BiOI, have attracted significant attention in the field of photocatalysis due to their remarkable properties. In this study, a unique architecture BiOBr/BiOI was designed facilitate rapid transfer electrons and holes, effectively mitigating recombination electron–hole pairs. Accordingly, nanosheet heterojunction anchored on dendritic fibrous nanosilica (DFNS) by immobilization Bi2O3 nanodots DFNS subsequent reaction with HBr then HI vapors...
The formation of BiOX (X = Br and Cl) nanoparticles in a mesoporous silica (SBA-15) was found by the reaction infiltrated bismuth oxo species with HX vapor at room temperature.
Rutile nanorods (single and connected nanorods) with diameter similar to the pore size of template (cylindrical mesopore SBA-15 a 8 nm) are prepared by infiltration partially hydrolyzed titanium alkoxide subsequent in situ crystallization reaction HCl vapor at room temperature. Morphological variation is achieved varying loading amount dioxide precursor mesoporous silica. The followed Raman spectra X-ray diffraction patterns. single rutile 5 nm 7 successfully collected dissolving silica...
