Conversion of methane to methanol: nickel, palladium, and platinum (d9) cations as catalysts for the oxidation of methane by ozone at room temperature.
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.
