• The room‐temperature chemical kinetics has been measured for the catalytic activity of Group 10 atomic cations in the oxidation of methane to methanol by ozone. Ni+ is observed to be the most efficient catalyst. The complete catalytic cycle with Ni+ is interpreted with a computed potential energy landscape and, in principle, has an infinite turnover number for the oxidation of methane, without poisoning side reactions. The somewhat lower catalytic activity of Pd+ is reported for the first time and also explored with DFT calculations. Pt+ is seen to be ineffective as a catalyst because of the observed failure of PtO+ to convert methane to methanol. Nickel is the best: The catalytic activity of M+ (M=Ni, Pd and Pt) in the oxidation of methane to methanol by ozone has been studied both experimentally and computationally. Ni+ is found to be the most efficient catalyst. The complete catalytic cycle with Ni+ has no poisoning side reactions and so proceeds, in principle, with an infinite turnover number.
