[Display omitted] •Co−doped zinc stannates were synthesized and tested against H2O2 oxidation.•Response to H2O2 was enhanced when cobalt is in pure phase.•A synergistic effect was obtained using reduced graphene oxide in a proportion 8:1/Co2SnO4:rGO.•Composite sensor response varied linearly with pe...
