Phase-changing VO₂ turns methane into propane and hydrogen more efficiently

Converting methane, the primary component of natural gas, into higher alkanes and hydrogen, could be highly advantageous. Alkanes, such as propane and butane, are easier to transport than methane and are used in a wider range of industries. Hydrogen, on the other hand, is a promising clean fuel used to power electrochemical devices that can generate continuous power, known as fuel cells.
