Hidden Nickel Oxide Structure Boosts Methane Catalyst Efficiency

Scientists have identified a nanoscale atomic structure that forms on nickel oxide during methane conversion and found it to be more effective than the metallic nickel that has long been considered the active catalyst. The discovery challenges the prevailing view that nickel metal is the primary driver of the reaction, which is a key step in converting natural gas into valuable chemicals and fuels.

The new catalyst, which contains far less nickel than traditional formulations, can match the performance of a catalyst that uses ten times more metal. By reducing the amount of nickel required, the breakthrough could lower material costs and improve the overall efficiency of industrial processes that rely on methane conversion. The finding also suggests that further optimization of nickel‑oxide interfaces may yield even more active and economical catalysts.

If the results can be replicated on a commercial scale, the technology could reshape the design of methane‑processing units, making them cheaper and more sustainable. The research opens a promising pathway toward next‑generation catalysts that combine high activity with reduced reliance on expensive metals.
