All rights reserved.The molecular diffusion with zeolites is somewhat limited, particularly for bulky molecules because zeolites only have micropores, which, in turn, limit their use as catalysts. Generation of hierarchically porous ZSM-5 with micro and mesopores has been a rational solution for overcoming this problem. The conventional method for synthesizing hierarchically porous ZSM-5 generally requires high-temperature heating in the presence of an organic structure-directing agent (OSDA) and a mesopore-generating agent (mesoporogen). Herein, we report a new method for the synthesis of hierarchically porous ZSM-5, which leads to the synthesis at low temperature in the presence of a reduced amount of OSDA and in the absence of any mesoporogen. The OSDA seems to play an additional role as a scaffolding agent for mesopore generation. Our study also showed that the control of the molar composition is essential for the crystallization of hierarchically porous-ZSM-5.[/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]Conventional methods,Hierarchically porous,High temperature heating,Mesoporosity,Molar compositions,Molecular diffusion,Non-hydrothermal,Organic structures[/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]Hierarchically porous ZSM-5,Mesoporosity,Morphology,Non-hydrothermal[/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]RRM is grateful for the short stay program from AUN/SEED-net and Institut Teknologi Bandung at the University of Tokyo, Japan.
