Communication: The advantages of in situ X‐ray diffraction in clarifying the onset and nature of the distinct kinds of catalytic action exhibited by a lithium nickel oxide for the oxidation of methane at elevated temperatures are demonstarted. Active solids may possess structural features quite unlike those deduced from measurements conducted at ambient temperatures and pressures emphasizing the need for the development of in situ methods.
