Ecofriendly catalyst for converting methane into useful gases using light instead of heat
(PHYSorg.com Chemistry)

Methane is present in the natural gas that is abundant in the Earth`s crust, and has found many uses in modern applications, mainly as a burning fuel. Alternatively, methane can be converted into a useful mixture of hydrogen and carbon monoxide, called `synthesis gas,` by reaction with carbon dioxide in what is referred to as dry reforming of methane (DRM). This DRM reaction is described as `uphill` because it requires the consumption of external energy; thermal reactors have to be at a high temperature of more than 800 degrees Celsius for efficient conversion. Reaching such high temperatures requires burning other fuels, resulting in massive greenhouse gas emissions, which are the leading cause of climate change. In addition, the use of high temperatures also causes the deactivation of commonly used catalysts due to aggregation and carbon precipitation (so-called coking).
