Crafting Zn/nano-H-ZSM-5 catalysts for methanol-to-aromatics conversion: tailoring crystal size and modifying surface electron density

Optimizing H-ZSM-5 crystal size (60–80 nm) shortens reactant diffusion paths, enhancing mass transfer and coke resistance. In MTA, Zn species exhibit electron-deficient Lewis acidity, synergistically improving catalytic performance.
