Each year, different species of catalysts are produced that play an important role in various sciences such as chemistry, medicine, and biotechnology. It would be valuable to implement the principles of green chemistry in their production. This way, we can utilize waste materials for recycling and converting them into precious compounds. In our study, we aimed to use olive pomace, food industry waste, as biomass to produce biochar nanoparticles. The surface of the biochar was coated with L-histidine ligand, and cupper metal was added for catalytic applications in the synthesis of aniline derivatives. Another notable feature of this catalyst is its reusability. It maintained significant efficiency even after multiple uses in reactions. To characterize the novel catalyst, we employed various techniques such as FT-IR, EDS, XRD, TGA, FE-SEM, and ICP. These analyses confirmed that our catalyst was well-formed [1-2].
