New paper on the stability of Na-Mn-W/SiO2 catalyst for the OCM has now been accepted at the Faraday Discussions!

A new paper by our former PhD student Dorota Matras and partners from MEMERE project has been accepted in the Faraday Discussions. In this study, we investigate the effect of thermal treatment/calcination on the stability and activity of a Na-Mn-W/SiO2 catalyst for the oxidative coupling of methane reaction. The catalyst performance and characterisation measurements suggest […]
