The as-prepared material has been characterized using X-ray diffraction, atomic absorption spectroscopy, UV–Vis diffuse reflectance spectroscopy, transmission electron microscopy, selected area electron diffraction and N2 physisorption. These characterizations confirm the well-defined gold nanoclusters formed on the surface of Au/INZ. Our catalyst has been applied for the reduction of p-nitrophenol to p-aminophenol. The reduction conversion of ca. 95 % was achieved by the use of 50 mg Au/INZ for 10 min with the observed rate constant (kobs) was of 0.818 min−1. The Ea of the reaction was 16.9 kJ/mol, indicating the diffusion-controlled mechanism. In addition, the reusability test confirmed that our catalyst can be exploited for several times without the significant loss of its high activity.[/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]Atomic absorption spectroscopy,Diffuse reflectance spectroscopy,Diffusion controlled mechanism,Gold nanocluster,Natural zeolites,p-Nitrophenol,Reusable catalysts,Selected area electron diffraction[/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]Catalytic activity,Gold nanoclusters,Natural zeolite,p-nitrophenol,Reduction[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1007/s11144-015-0916-2[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
