Hierarchical mesoporous CuO/ZrO2 nanocomposite photocatalyst for highly stable photoinduced desulfurization of thiophene

The lattice oxygen determines the methanol selectivity in CO2 hydrogenation over ZnZrOx catalysts

“…The characteristic diffraction peaks corresponding to tetragonal phase ZrO 2 (t-ZrO 2 ) (PDF#50-1089) and monoclinic phase ZrO 2 (m-ZrO 2 ) (PDF#83-0941) were found for all these six catalysts from the observed patterns. 39 The diffraction peaks at 2theta = 50° and 62° between ZnO and ZrO 2 were assigned to ZnZrO x solid solution, 23 indicating that the ZnZrO x solid solution catalyst was successfully formed. In addition, no characteristic diffraction peak of ZnO (PDF#36-1451) was observed in the image.…”
