Abstract:
An electrode (100) for an electrochemical gas sensor (1), wherein the electrode has a gas-permeable membrane (4). A graphene layer (3) is applied as an electrode material to the gas-permeable membrane (4). Such an electrode (1) is prepared, for example, by applying a dispersion of graphene or graphene oxide in a volatile liquid to the gas-permeable membrane and evaporating the volatile liquid.
