Biochar is a highly porous, carbon - based material produced from a range of different biomass, usually either vegetal or animal waste, under low - oxygen conditions that I have significant aromatization and anti - decomposition capabilities. Biochar is reported to have a high specific surface area and contain a wide variety of negative surface functional groups (e.g., hydroxyl, carboxyl, amino) , and therefore it has gained the interest of the scientific community in a multifunctional fields such as support for catalysis synthesis [ 1 ] . Novel catalyst based on zinc oxide on biochar is prepared through a simple route and is proposed for the synthesis of 5-amino-1H-pyrazole-4-carbonitrile derivatives. Highly effective biochar / ZnO catalysed via one - pot multi - component reaction, by Using the phenyl hydrazine, malononitrile and aldehyde under optimal conditions. The salient features of this nanocomposite as catalyst are: easy preparation, cost effective, high stability and reusability of the catalyst [ 2 ]
