Device (1) for treating an exhaust-gas flow (2), having at least one inflow passage (3) with a front region (4) and a rear region (5) and at least one return flow passage (6), wherein a first coating (7) is provided in the rear region (5) of the at least one inflow passage (3), said coating (7) assisting an exothermal reaction of the exhaust-gas flow (2), and means for the transfer of heat from a return flow passage (6) are formed in the front region (4) of the inflow passage (3). Furthermore, a corresponding method for operating a device (1) for treating an exhaust-gas flow (2) is also proposed.
