MOF derived hollow CuO/ZnO nanocages for the efficient and rapid degradation of fluoroquinolones under natural sunlight

Room Temperature Engineering Crystal Facet of Cu2O for Photocatalytic Degradation of Methyl Orange

“…However, the CB position of Cu 2 O (about −0.09 eV) is more positive than the redox potential of O 2 to ∙O 2 − (−0.33 eV) and the VB position of Cu 2 O (1.87 eV) is more negative than the redox potential of H 2 O to ∙OH (1.99 eV) [ 54 ]; these results did not correspond with those of ESR. This may be because the partial oxidation of the Cu 2 O surface generates CuO, which constitutes the heterojunction and thus affects the band gap position [ 55 ]. According the previous report [ 43 ], the reasons why Cu 2 O self-photooxidation does not happen in the absence of h + scavenger may be that the MO dye acts as a h + scavenger or generates CuO (Equation (8)) is reduced to Cu 2 O by accumulated photogenerated e - in the CB of Cu 2 O (Equation (5)).…”

Identification of catalytic activity descriptors for selective 5-hydroxymethyl furfural electrooxidation to 2,5-furandicarboxylic acid

“…98 The presence of CuO in the postreaction CuFe lm can be assigned to the Cu 2p 3/2 peak at 936.3 eV and the Cu 2p 1/2 peak at 956.1 eV. 99 Both CuO and Cu 2 O phases were not observed in the XANES prole due to the bulk nature of the measurement. Based on the characterisation data, we propose that CuO likely supersedes Cu(OH) 2 as the As shown above, the Co, Ni, and Cu-precursors in the PBA lms result in different phase evolutions during HMF electrooxidation.…”

Enhanced photocatalytic performance of anatase titania nanotubes via the synergistic effect of trace copper doping and oxygen vacancies

“…67,68 The isotherm grows slowly when the relative pressure is low and rises rapidly when the pressure is high, which indicates that there are both macropores and mesopores in the sample. 68,69 Fig. 5(b) shows that the pore size distribution ranges from 2 to 70 nm, and the most probable pore size is 12.75 nm.…”
