Activation of peroxymonosulfate with CuCo2O4@kaolin for the efficient degradation of phenacetin

A novel CoNi7O8/MnO2 nanocomposite supported on Ni foam as a peroxymonosulfate activator for the highly efficient singlet oxygen mediated removal of methylene blue

“…To confirm the ROS produced during PMS activation over the CoNi 7 O 8 /MnO 2 /NF catalyst, methanol was utilized as an ˙OH and SO 4 ˙ − scavenger and furfuryl alcohol (FFA) was used to probe 1 O 2 . 29 The results in Fig. 9 show that when 0.2 M methanol was added to the reaction system, a slight decrease in phenol degradation performance occurred, indicating ˙OH and SO 4 ˙ − were involved in the phenol oxidative degradation, but their contribution was small.…”

Selective Hydrogenation of 5-Hydroxymethylfurfural to 2,5-Dimethylfuran Over Popcorn-Like Nitrogen-Doped Carbon-Confined CuCo Bimetallic Catalyst

“…Two peaks are visible at 284.8 and 286.0 eV in the high-resolution XPS spectrum of C 1s mainly corresponding to C–C and C–O–C ( Xia et al, 2016 ; Rao et al, 2021 ). The peak near 289.0 eV is attributed to C–N in the catalyst ( Figure 3A ) ( Liu L et al, 2020 ; Zhu K et al, 2020 ). Two peaks were visible at 398.6 and 401.2 eV in the high-resolution XPS spectrum of N 1s corresponding to pyridine N and graphite N ( Figure 3B ) ( Hu et al, 2019 ).…”

Materials Based on Co, Cu, and Cr as Activators of PMS for Degrading a Representative Antibiotic—The Strategy for Utilization in Water Treatment and Warnings on Metal Leaching

“…The CIP degradation rate decreased slightly after each cycle. As occurs with other catalysts employed for PMS activation, the catalyst could adsorb some molecules of CIP, or its byproducts, onto the surface during the degradation process [41,42], and such adsorbed substances are not completely removed in the recycling tests. Therefore, a small portion of the active sites is occupied, resulting in a slight decrease in the catalytic performance of the MMO to activate the PMS and produce the radicals that are responsible for CIP degradation (see the SBET results for the used MMO in Table 2, which had a slightly lower SBET than the Φy material).…”
