Sulfate radicals induced from peroxymonosulfate by cobalt manganese oxides (Co x Mn 3−x O 4 ) for Fenton-Like reaction in water

Application of Spent Li-Ion Batteries Cathode in Methylene Blue Dye Discoloration

“…This process is very interesting concerning the environment due to the possibility of promoting the decontamination of organic pollutants using a residue coming from Li-ion battery waste. The substances traditionally used for organic decontamination are O 3 and H 2 O 2 [7]. However, the cost of these compounds is relatively high (O 3 is $2.2 per kg and H 2 O 2 is $1.5 per kg) [7].…”

“…The substances traditionally used for organic decontamination are O 3 and H 2 O 2 [7]. However, the cost of these compounds is relatively high (O 3 is $2.2 per kg and H 2 O 2 is $1.5 per kg) [7]. The use of LiCoO 2 increases the velocity constant of methylene blue (MB) degradation 200 times if compared to pure H 2 O 2 with minimum additional cost since this material comes from spent LIB [3].…”

Characterization and Catalytic Activity of Mn-Co/TiO2 Catalysts for NO Oxidation to NO2 at Low Temperature

“…The spectra of Mn 2p 3/2 could be separated into three peaks. The peaks corresponding to the higher, middle and lower binding energy were attributed to Mn 4+ , Mn 3+ and Mn 2+ , respectively [25,26]. Their relative atomic ratios in the surface layer are listed in Table 2.…”

Facile synthesis of Fe3O4/MIL-101 nanocomposite as an efficient heterogeneous catalyst for degradation of pollutants in Fenton-like system

“…[32][33][34] The actual reactive specie mediating the process was identied by determining the inuence of TBA as a radical scavenger on the degradation of RhB, as shown in Fig. 9a.…”
