Abstract Synthesis of micro‐mesoporous zeolite composite with optimum micro and mesoporosity is an emerging research area due to its wide applications, especially in bulk chemical or biomass transformations. It offers advantages preserving crystallinity, creating converting bulky molecules into valuable products. This work presents the process preparing bimodal ZSM‐5 using dual templates (CTMABr TPABr). XRD, N 2 adsorption–desorption, SEM, TEM, 29 Si, 27 Al NMR were used analyze two‐dimensional ZSM‐5. One‐step synthesis features micro/mesoporosity by a marginal decrease crystallinity (71%). Micro‐mesoporous was found be dependent on CTMABr/SiO molar ratio 0.04 0.06. The evaluated for cascade 5‐EMF (methoxymethyl furfural‐ biofuel additive) from fructose exhibited five fold increase yield 24.2% as compared parent (4.6%).
