چکیده مقاله :
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 ] .()
