Advances in bi-reforming of methane: Syngas production for low-carbon energy solutions

Syngas, composed mainly of H2 and CO, is a key intermediate for the synthesis of chemicals and fuels. Traditionally, syngas is produced from steam methane reforming (SMR), a well-established but carbon-intensive process. With increasing global decarbonization efforts and high carbon footprint associ...
