Multicomponent transport model-based scaling up of long-term fixed bed adsorption of reactive dyes from textile effluent using aminated PAN beads

Photocatalytic degradation of rhodamine-B by visible light assisted peroxymonosulfate activation using the Z-scheme MIL-100(Fe)/Bi2S3 composite: a combined experimental and theoretical approach

“…70,75,76 Three peaks are obtained in the high-resolution spectrum of C1s in the nascent composite at 284.29 eV, 285.53 eV and 288.78 eV, which are attributed to sp 2 C-C bonding in the aromatic rings, Fe-O-C bonding and -COOH moieties (CQO) of the H 3 BTC linkers. [77][78][79] Deconvolution of the S2p spectrum of the nascent composite generates three peaks at 160.53 eV (S2p 3/2 ), 161.72 eV (S2p 1/2 ) and 167.21 eV, implying the presence of S 2À groups. 70,73,76 In the reacted catalyst, the peaks in the Fe2p spectrum are shifted slightly at 710.63 eV (Fe2p 3/2 ), 712.21 eV (Fe2p 3/2 ) and 725.41 eV (Fe2p 1/2 ), compared to the nascent composite, implying gaining of e À s during the reaction and slight interconversion of Fe 3+ into Fe 2+ .…”
