Sustainable nano-hybrids of magnetic biochar supported g-C 3 N 4 /FeVO 4 for solar powered degradation of noxious pollutants- Synergism of adsorption, photocatalysis & photo-ozonation

Single-step synthesis of eucalyptus sawdust magnetic activated carbon and its adsorption behavior for methylene blue

“…As for N 1s, NH 2 (399.6728 eV), 69 is exhibited in Fig. 11i before MB adsorption, as N-H or -CO-NH-(399.118 eV), 73,74 and a new peak (401.615 eV) appeared, which was either N + binding in…”

Recent progress in biochar-supported photocatalysts: synthesis, role of biochar, and applications

“…The list of BSPs which have been synthesized and their applications in various elds are summarized in Table 1. Organic pollutants whose photodegradation by BSPs have been published at least once include phenol, 28,77 bisphenol A, 38 methylene blue, 29,33,37,75 safranin T, 41 anthraquinone, 32 malic acid, 59 sulfamethoxazole, 25,30,34 methyl paraben, 35 2-chlorophenol, 35 Reactive Yellow 39, 36 methyl orange 39 in the liquid phase, and methanol in the gas phase. 28 Among the listed pollutants, methylene blue is the most commonly studied pollutant followed by sulfamethoxazole and phenol.…”

Recent Progress in Biochar-Based Photocatalysts for Wastewater Treatment: Synthesis, Mechanisms, and Applications

“…In recent years, biochar-based photocatalysts (BCPs) have received great attention in various environmental fields [23][24][25][26][27]. Some of those recently reported BCPs were TiO 2 -coconut shell [28], TiO 2 -Salvinia molesta [29], TiO 2 -reed straw [30], TiO 2 -ramie char [31], TiO 2 -corn cob [32], TiO 2 -paper sludge and wheat husks [33], TiO 2 -bamboo [34,35], ZnO-waste biomass [36], g-C 3 N 4 /FeVO 4 -pinus roxbu rghii [37], Bi 2 O 3 -corn cobs [38], TiO 2 -walnut shells [39], TiO 2 -olive pits and TiO 2 -wood shaving [40], TiO 2 -wood pellets [41], and TiO 2 -plum stones [42], etc.…”
