Abstract:In the process of using photocatalysts to treat tetracycline (TC) wastewater, the degradation efficiency of soybean powder carbon material (SPC) can be improved by loading it with cerium oxide (CeO2). In this study, firstly, SPC was modified by phytic acid. Then, the CeO2 was deposited on modified SPC using the self-assembly method. Catalyzed cerium (III) nitrate hexahydrate (CeH3NO4) was treated with alkali and calcined at 600 °C under nitrogen. XRD, XPS, SEM, EDS, UV-VIS /DRS, FTIR, PL and N2 adsorption–deso… Show more
“…, carboxyl, phenol, hydroxyl, and acid anhydride) that promote contaminant removal. 20 However, BC cannot provide sufficient electrons for PMS activation, which results in lower catalytic efficiency. 21 Studies have shown that the introduction of metals can improve PMS activation.…”
Biochar (BC) modified by Fe@Mn was employed to activate PMS to degrade CBZ in water. The surface of Fe@Mn–BC presented a dense, stalactite-like morphology. The catalyst Fe@Mn–BC had an optimal degradation effect (99%) on CBZ at 100 min.

“…Recently, He et al studied CeO 2 loaded soybean powder carbon as a photocatalyst for TC degradation. 21 As a comparison, they tested CeO 2 obtained by the cerium( iii ) nitrate hexahydrate (CeH 3 NO 4 ) treated with alkali and calcined at 600 °C under nitrogen without soybean powder carbon. The result, after 180 min indicate only 20% of TC removal.…”
Water pollution is a global environmental issue, and the presence of pharmaceutical compounds, such as tetracyclines (TCs), in aquatic ecosystems has raised growing concerns due to the potential risks to both the environment and human health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
