Visible-light (VL) photocatalysis has been regarded as an intriguing technol. for the control of persistent environmental pollutants. In this study, the novel homogeneous Co doped-Bi/BiOBr nanocomposites (CB-X) were prepared via a facile one-step hydrothermal method, featured with a uniform 0D Bi nanodots distribution on 2D Co-doped BiOBr nanosheets, and the photocatalytic performance was evaluated by decomposing the BPA as a prototype contaminant. The degradation experiment indicated that the optimal CB-2 nanocomposite exhibited the best photocatalytic activity with a 94% removal efficiency of BPA under the VL irradiation of 30 min; And the corresponding apparent rate constant (k) was as high as 0.107 min-1, which was 10.7 times greater than that of Bi/BiOBr (0.010 min-1). Benefiting from the modulation effect of Co-doping on the intrinsic electron configuration of Bi/BiOBr, the elevated VL adsorption capacity and accelerated h+/e– pairs separation rate were achieved, which were evidenced by photoluminescence (PL) spectroscopy, photo-electrochem. measurements and d. functional theory (DFT) calculation Moreover, the major reactive species in CB-X/VL system were uncovered to be •O-2 and 1O2, whereas •OH and h+ presented a secondary contribution in the BPA elimination. Finally, the possible photocatalytic mechanism involved in CB-X nanocomposites and BPA degradation pathways were proposed on the basis of the various intermediates and products detected by LC-MS/MS. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Computed Properties of C13H12O2).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Computed Properties of C13H12O2
