Enhanced catalytic performance of hierarchical Zn/ZSM-5 with balanced acidities synthesized utilizing ZIF-14 as porogen and Zn source in methanol to aromatics

Influence of Mo modification on coaromatization coupling methanol with n-hexane over [Zn,Mo]/HZSM-5 catalysts

“…22 Geng et al 23 proposed Zn(OH) + species as the active sites responsible for the methanol-to-aromatics (MTA) reaction, where the amount of Zn(OH) + species was linearly correlated with the selectivity for aromatics. Recently, Liu et al 24 reported a series of Zn loaded ZSM-5 catalysts prepared via a one-step hydrothermal method utilizing Zn(NO 3 ) 2 or Zn-based MOFs as Zn sources, which exhibited an aromatic selectivity of 50.9% in the MTA reaction at 460 °C, 0.15 MPa and WHSV = 1.9 h −1 .…”
