The present work explored the synthesis of N-S containing graphene from nitrogen-rich fruit wastes in the presence of urea and thiourea. Since pure graphene exhibited limited electrocatalytic activity due to a low number of active sites, it is highly recommended to introduce multi-heteroatoms into the graphitic lattice, increasing electrical conductivity and interlayer spacing graphene. The results suggested that urea and thiourea played a dual role as they were involved in the cyclization and aromatization to form a graphitic lattice and introduced nitrogen and sulfur atoms within the lattice pyrolysis. The utilization of urea and thiourea facilitated the development of N-S containing graphene from fruit wastes and prevented oxygen's attack between 250-350 oC under normal atmospheric conditions.
