Sonocatalytic Activity of Porous Carbonaceous Materials for the Selective Oxidation of 4-Hydroxy-3,5-dimethoxybenzyl Alcohol

“…The XPS C1s spectrum was deconvoluted into six distinguished peaks at 284.2, 258.9, 287.5, 289.2, 290.7, and 292.5 eV. These peaks are associated with C sp 2 , C sp 3 , and carbon bound to oxygen (C-O) in esters or phenol structures, the double bond between carbon and oxygen (C=O) in quinones and ketones, two oxygen atoms in carboxylic acid, carboxyl, or esters (-COO), and carbonates, respectively [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. It is interesting to point out that the carbonaceous materials derived from sucrose (C-meso and CN-meso) present a smaller ratio between Csp 3 and Csp 2 than CN-meso Chit and CN-meso Gluc.…”

“…They exhibit both nucleation effects and unique physicochemical properties that enhance the sonocatalytic degradation process [36,37]. A range of carbonaceous materials, including carbon nanotubes (CNTs), graphene (GR), graphene oxide (GO), reduced graphene oxide (rGO), activated carbon (AC), biochar (BC), g-C3N4, buckminsterfullerene (C60), mesoporous carbon, and doped-carbon have garnered attention for water and wastewater treatment applications and catalysis [17,[38][39][40].…”

Green chemistry: advancing planetary phosphorus sustainability through the synergy of graphene oxide modified with magnetic nanoparticles (M@GO) for extracting tertiary effluent phosphorus in sewage treatment plants

“…Additionally, it features a rich system of delocalized π–π electrons that strongly interacts with organic compounds. 22 GO can be modified with magnetic nanoparticles (MNPs) 23,24 for use in magnetic solid phase extraction (MSPE). In this work, a novel patented magnetic graphene oxide 25 was synthesized through double coupling between iron oxide MNPs and GO, and was called M@GO.…”
