The cover image shows the initiation of oxidative reforming (OR) of n ‐butane to produce H 2 and CO over a Rh/Ce 0.5 Zr 0.5 O 2 catalyst cooled in an ice bath. The catalyst generates heat internally though oxidation of the Ce 0.5 Zr 0.5 O 2− x support, and is immediately heated above the catalytic autoignition temperature of n ‐butane combustion, which eventually drives OR. In their communication on page 1032, Katsutoshi Nagaoka, Katsutoshi Sato, Yusaku Takita, and co‐workers from Oita University show that Rh/Ce 0.5 Zr 0.5 O 2 is reduced sufficiently even under mild conditions (i.e., in an H 2 atmosphere at 373 K) and in situ during OR, and the oxidation of the resultant catalyst triggers OR at an ambient temperature without any external heat input (even under nonadiabatic conditions). This research is considered to represent an innovative step in the development of self‐sufficient reforming systems for a new generation of fuel cell application.
