All rights reserved.We demonstrated the synthesis of spherical nanostructured γ-Al2O3 using reverse micelle templating to enhance the surface area and reactant accessibility. Three different surfactants were used in this study: benzalkonium chloride (BZK), sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB). We obtained spherical nanostructured particles only using CTAB that form a reverse micelle emulsion. The particles have wide size distribution with an average size of 2.54 μm. The spherical particles consist of nanoplate crystallites with size 20-40 nm randomly arranged forming intercrystallite spaces. The crystalline phase of as-synthesized and calcined particles was boehmite and γ-Al2O3,respectively as determined by XRD analysis. Here, the preserved particle morphology during boehmite to γ-Al2O3 transformation opens a facile route to synthesize γ-Al2O3 particles with complex morphology. The specific surface area of synthesized particles is 201 m2/g, which is around five times higher than the conventional γ-Al2O3 (Aldrich 544833). Spherical nanostructured γ-Al2O3 provides wide potential applications in catalysis due to its high density closed packed structure, large surface area, and high accessibility.[/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]Benzalkonium chloride,Boehmite,Cetyltrimethylammonium bromide,Closed packed structures,CTAB,Nanostructured particles,Reverse micelles,Wide size distribution[/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]Boehmite,CTAB,Reverse micelle,Spherical nanostructured particle,γ-Al2O3[/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]This research was financially supported by Penelitian Dasar Unggulan Perguruan Tinggi (PDUPT) Research Grant No. 1/E/KPT/2018, Ministry of Research, Technology and Higher Education, Republic of Indonesia.
