Abstract

Read online

Gallium-modified HZSM-5 zeolites demonstrate increased selectivity towards aromatics during methanol conversion, but the mechanism and the nature of the active sites that lead to this enhanced selectivity are poorly understood. Here, in situ synchrotron radiation photoionization mass spectrometry experiments reveal that increased formaldehyde generation over Ga2O3 species plays a key role in promoting the production of aromatic compounds.
