Schematic of (a) process employed for synthesizing the graphene–selenium hybrid microballs (denoted as G–SeHMs), involving the use of a commercial spray dryer for drying aerosol microdroplets of the GO/surfactant-decorated Se/hydrazine hydrate suspension, (b) formation of a stable Se suspension by the addition of Triton X-100 as a non-ionic surfactant and photographs of the colloidal Se suspension without/with Triton X-100 and (c) the proposed morphology of G–SeHMs.
