Influence of dendrimeric silica BEA zeolite towards acidity and mesoporosity for enhanced benzene methylation

Fibrous silica BEA zeolite (FBEA) was synthesized by microemulsion method and tested for benzene methylation. The FESEM and N2physisorption verified that the FBEA exhibited a dendrimeric silica fiber morphology with large surface area and high ratio of mesopores and micropore volume. While the FTIR...
