The ligands were further transformed into two nickel(II) complex, C1 and C2, as the precursors of catalysts in glucose conversion to sorbitol. The two NiO/SiO2 catalysts, K1 and K2, have been generated through the calcination process of complex C1 and C2, respectively, which were previously impregnated into silica. The K1 catalyst with average particle size of 5 nm shows good catalytic activity, with no presence of any nickel leached into the solution, and has successfully converted 21.99% of glucose into sorbitol. The K2 catalyst with average particle size of 10 nm also shows good catalytic activity and has successfully converted 32.30% of glucose into sorbitol, although it shows the presence of leached nickel.[/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]Average particle size,Catalyst precursors,Glucose conversion,Imine derivatives,Microwave assisted synthesis,Nickel complex,Organic synthesis,Sorbitol[/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]Catalyst,Glucose,Imine derivatives,MAOS (Microwave-Assisted Organic Synthesis) method,Nickel(II) complex,Sorbitol[/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]Acknowledgements are made to ITB for the full support of funding the research under the scheme of Research and Innovation Project for Research Groups in Bandung Institute of Technology (Riset KK ITB) under contract no. 241/I.1.C01/PL/2011 and Puspiptek LIPI Serpong for the NMR measurements.[/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/10.4028/www.scientific.net/KEM.811.47[/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]
