Popis: The preparation of micro-mesoporous zeolite with controlled mesoporosity is an expanding area of research having advantages in term of the creation of mesoporosity by preserving crystallinity of zeolite; converting bulky molecules to valuable products etc. The present work is a successful attempt to synthesize micro-meso ZSM-5 composite in one step using cheaper silica (sodium silicate) and alumina (aluminiumsulphate) as source material with dual templates (CTMABr and TPABr). The insitu mesoporous creation in a controlled way by using these source materials is rarely reported. The facile one-step synthesis of micro-mesoporous ZSM-5 composite feature dual Meso/microporosity by the marginal decrease in crystallinity(71%)and mesoporous creation in micro-ZSM-5 found to be depend on optimum CTMABr/SiO2 molar ratio in the range of 0.04 to 0.06. The micro-mesoporous ZSM-5 composite zeolite was evaluated for cascade synthesis of 5-EMF (ethoxymethyl furfural- biofuel additive) from fructose, exhibited 5 fold increase in EMF yield of 24.2% than micropous ZSM-5 4.6%.
