Abstract

etc. with higher IEs, thereby reducing the need for separate measurements at multiple photon energies. The optimized SR-PIMS setup combined with RGA was successfully applied to probe the intermediates and products generated during the methanol-to-hydrocarbons (MTH) reaction over ZnO/HZSM-5 catalysts, and the time-evolved profiles for major species under different ZnO loadings were obtained and analyzed.
