Efficient Degradation of Congo Red in Water by UV-Vis Driven CoMoO<sub<4</sub</PDS Photo-Fenton System

In order to improve the catalytic activity of cobalt molybdate (CoMoO<sub<4</sub<), a PDS-activated and UV-vis assisted system was constructed. CoMoO<sub<4</sub< was prepared by coprecipitation and calcination, and characterized by XRD, FTIR, Raman, SEM, TEM, XPS, TGA Zeta po...

520			\|a In order to improve the catalytic activity of cobalt molybdate (CoMoO<sub<4</sub<), a PDS-activated and UV-vis assisted system was constructed. CoMoO<sub<4</sub< was prepared by coprecipitation and calcination, and characterized by XRD, FTIR, Raman, SEM, TEM, XPS, TGA Zeta potential, BET, and UV-Vis DRS. The results showed that the morphology of the CoMoO<sub<4</sub< nanolumps consisted of stacked nanosheets. XRD indicated the monoclinic structures with C2/m (C<sup<3</sup<<sub<2h</sub<, #12) space group, which belong to α-CoMoO<sub<4</sub<, and both Co<sup<2+</sup< and Mo<sup<6+</sup< ions occupy distorted octahedral sites. The pH of the isoelectric point (pHIEP) of CMO-8 at pH = 4.88 and the band gap of CoMoO<sub<4</sub< was 1.92 eV. The catalytic activity of CoMoO<sub<4</sub< was evaluated by photo-Fenton degradation of Congo red (CR). The catalytic performance was affected by calcination temperature, catalyst dosage, PDS dosage, and pH. Under the best conditions (0.8 g/L CMO-8, PDS 1 mL), the degradation efficiency of CR was 96.972%. The excellent catalytic activity of CoMoO<sub<4</sub< was attributed to the synergistic effect of photo catalysis and CoMoO<sub<4</sub<-activated PDS degradation. The capture experiments and the ESR showed that superoxide radical (·O<sub<2</sub<<sup<−</sup<), singlet oxygen (<sup<1</sup<O<sub<2</sub<), hole (h<sup<+</sup<), sulfate (SO<sub<4</sub<<sup<−</sup<·), and hydroxyl (·OH<sup<−</sup<) were the main free radicals leading to the degradation of CR. The results can provide valuable information and support for the design and application of high-efficiency transition metal oxide catalysts.

CoMoO<sub<4</sub< was prepared by coprecipitation and calcination, and characterized by XRD, FTIR, Raman, SEM, TEM, XPS, TGA Zeta potential, BET, and UV-Vis DRS. The results showed that the morphology of the CoMoO<sub<4</sub< nanolumps consisted of stacked nanosheets. XRD indicated the monoclinic structures with C2/m (C<sup<3</sup<<sub<2h</sub<, #12) space group, which belong to α-CoMoO<sub<4</sub<, and both Co<sup<2+</sup< and Mo<sup<6+</sup< ions occupy distorted octahedral sites. The pH of the isoelectric point (pHIEP) of CMO-8 at pH = 4.88 and the band gap of CoMoO<sub<4</sub< was 1.92 eV. The catalytic activity of CoMoO<sub<4</sub< was evaluated by photo-Fenton degradation of Congo red (CR). The catalytic performance was affected by calcination temperature, catalyst dosage, PDS dosage, and pH. Under the best conditions (0.8 g/L CMO-8, PDS 1 mL), the degradation efficiency of CR was 96.972%. The excellent catalytic activity of CoMoO<sub<4</sub< was attributed to the synergistic effect of photo catalysis and CoMoO<sub<4</sub<-activated PDS degradation. The capture experiments and the ESR showed that superoxide radical (·O<sub<2</sub<<sup<−</sup<), singlet oxygen (<sup<1</sup<O<sub<2</sub<), hole (h<sup<+</sup<), sulfate (SO<sub<4</sub<<sup<−</sup<·), and hydroxyl (·OH<sup<−</sup<) were the main free radicals leading to the degradation of CR.

abstract	In order to improve the catalytic activity of cobalt molybdate (CoMoO<sub<4</sub<), a PDS-activated and UV-vis assisted system was constructed. CoMoO<sub<4</sub< was prepared by coprecipitation and calcination, and characterized by XRD, FTIR, Raman, SEM, TEM, XPS, TGA Zeta potential, BET, and UV-Vis DRS. The results showed that the morphology of the CoMoO<sub<4</sub< nanolumps consisted of stacked nanosheets. XRD indicated the monoclinic structures with C2/m (C<sup<3</sup<<sub<2h</sub<, #12) space group, which belong to α-CoMoO<sub<4</sub<, and both Co<sup<2+</sup< and Mo<sup<6+</sup< ions occupy distorted octahedral sites. The pH of the isoelectric point (pHIEP) of CMO-8 at pH = 4.88 and the band gap of CoMoO<sub<4</sub< was 1.92 eV. The catalytic activity of CoMoO<sub<4</sub< was evaluated by photo-Fenton degradation of Congo red (CR). The catalytic performance was affected by calcination temperature, catalyst dosage, PDS dosage, and pH. Under the best conditions (0.8 g/L CMO-8, PDS 1 mL), the degradation efficiency of CR was 96.972%. The excellent catalytic activity of CoMoO<sub<4</sub< was attributed to the synergistic effect of photo catalysis and CoMoO<sub<4</sub<-activated PDS degradation. The capture experiments and the ESR showed that superoxide radical (·O<sub<2</sub<<sup<−</sup<), singlet oxygen (<sup<1</sup<O<sub<2</sub<), hole (h<sup<+</sup<), sulfate (SO<sub<4</sub<<sup<−</sup<·), and hydroxyl (·OH<sup<−</sup<) were the main free radicals leading to the degradation of CR. The results can provide valuable information and support for the design and application of high-efficiency transition metal oxide catalysts.
