The synthesis process was carried out by hydrothermal method without any structure directing agent or organic template. Synthesized products were analyzed by X-ray diffractometer, fourier transform infra red (FTIR) spectrometer, N2 physisorption analyzer, and Transmission Electron Microscope. Synthesis with tetraethylorthosilicates (TEOS) as additional silica source in different hydrothermal condition produce impure ZSM-5, while pure ZSM-5 was successfully produced by the addition of sodium oxalic and magnesium chloride mixture prior the optimized hydrothermal condition. Hierarchical porosity was obtained from post-synthesis treatment trough desilication.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Thank you to the Indonesian Ministry of Research, Technology and Higher Education for the funding provided for “Unggulan” Research.
