Abstract

One-step facile synthesis of boron containing ZSM-5 microspheres is developed using 1,6-diaminohexane as the structure-directing agent and cetyltrimethylammonium bromide as the mesoporogen. High boron incorporation up to Si/B ratio of 38 is achieved and evidenced by the stretching vibrations of B-O-Si at 667 cm$^{-1}$ and 917 cm$^{-1}$ using Fourier-transform infrared spectra. The morphology of the crystals resembles berry-like spheres with sizes approximately 15 μm, which is composed of aggregated nanocrystals having sizes around 450 nm, is observed using scanning electron microscopy. The textural properties, i.e. the surface areas and pore volumes are investigated using N$_{2}$ adsorption at -196 $^{\circ}$C. t-plot micropore volume of 0.11 cm$^{3}$/g and mesopore volume of 0.14 cm$^{3}$/g are obtained applying this synthesis method for mesopores having pore diameters within the range of 2-10 nm.
