A reactor assembly is provided. The reactor assembly includes a substrate and a first catalytic layer provided on the substrate. The first catalytic layer further includes a first temperature zone configured to operate at a first temperature. The first catalytic layer further includes a second temperature zone extending from the first temperature zone. The second temperature zone is configured to operate at a second temperature. The second temperature is lower than the first temperature. The reactor assembly also includes a diffusion barrier coating provided on the first catalytic layer. The diffusion barrier coating is configured to regulate a diffusion of gas phase oxygen therethrough for controlling the first temperature with respect to the second temperature.
