Introducing advanced carbon nanomaterials can provide considerable developments in the feld of heterogeneous catalysis. In this study, a novel magnetic biochar was prepared via carbonization of semi-parasite Loranthus europaeus plants (wood waste) and Fe3O4-nanoparticles as precursor. Magnetic biochar was subsequently coated with Cu(II) complex to obtain a costefective and biocompatible catalyst, i.e., magnetic biochar bis(thiourea) triazine copper (II) complex (MBC@BTT-Cu(II)). This nanocatalyst is capable of promoting C–O bond-forming processes, which allows the formation of phenols in the natural deep eutectic as environmentally, friendly media and neoteric green solvents for the frst time. The structures and properties of MBC@BTT-Cu(II) were fully characterized using various physicochemical techniques such as SEM, EDS, TGA, XRD, VSM, BET, CHN, AAS, and elemental mapping analysis. Furthermore, the as-prepared catalyst can be easily separated magnetically for several consecutive runs and exhibits signifcant recyclability without incredibly losing its activities.
