Adding water to the catalytic reaction that converts methane into useful methanol makes the process more effective, but it creates challenges for industry due to steam from the water. Now scientists have identified a common industrial catalyst, copper-zinc oxide, that completes the conversion along different pathways depending on whether water is present or not. This could potentially keep methane, a potent greenhouse gas, out of Earth’s atmosphere and instead turn it into useful products.
