Electrical behavior: (a) current-voltage characteristics of a graphene sensor before and after Pd decoration, (b) resistance responses of a Pd-decorated graphene sensor for 3% H2 under purple light illumination (thick line) and in the dark (thin line), and (c) resistance responses of a pure graphene sensor for 3% H2 at 20 °C in air.
