AgGaS2 (AGS) nanocrystals that exist in the orthorhombic phase were successfully prepared for the first time through a one-pot colloidal synthetic strategy using suitable coordinating solvents. These orthorhombic AGS nanocrystals were found to display great potential in visible-light-driven photocatalysis.
Aiming at clarifying the interplay on TiO2 photoactivity between particle morphology and surface fluorination, photocatalytic performance of anatase nanocrystals, characterized by a pseudo-spherical shape or nanosheet structure, is investigated in both reduction an oxidation reaction, either absence presence added fluoride anions. Cr(VI) strongly favored large exposure {001} facets; however, fl...
In this research, TiO2 nanoparticles were synthesized by a simple wet chemical method. TiCl4 was used as precursor in hydrogen peroxideand ethanol. The TiO2 nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), electron dispersive spectroscopy (EDS) and UV-Vis spectrophotome...
Photocatalytic oxidation of methanol on various anatase TiO2 nanocrystals was studied by in situ and time-resolved characterizations DFT calculations. Surface site resulting surface adsorbates affect the band bending/bulk-to-surface charge migration processes interfacial electronic structure/interfacial transfer processes. predominantly enclosed {001} facets expose a high density reactive fourf...
