The BLA with very high silica purity (ca. 99%) was obtained from combustion of acid-treated bamboo leaves, a cheap and abundant agriculture waste. The formation of zeolite A from the BLA precursor was studied by varying the synthesis conditions, i.e. crystallization time, heating temperature and initial gel molar composition. The study revealed that the synthesis parameters had profound effects on crystalline phase, morphology and crystal size of the zeolite A produced. Moreover, this study also demonstrated that the BLA-synthesized zeolite A showed excellent catalytic performance in solvent-free cyanoethylation reaction of methanol under moisture-tolerant and autogenic pressure conditions, with ca. 82% reactant conversion and 100% product selectivity even reused up to ten reaction cycles.[/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]Aluminosilicate zeolites,Bamboo leaf,Base catalyst,Catalytic performance,Product selectivities,Synthesis conditions,Synthesis parameters,Zeolite-A[/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]Bamboo leaf ash,Base catalyst,Cyanoethylation of alcohols,Hydrothermal synthesis,Zeolite A[/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]The financial support from RUI ( 1001/PKIMIA/811264 ) and FRGS ( 203/PKIMIA/6711495 ) Grants, and NIE Academic Research Fund (AcRF Project RI 5/12 WKL ) is gratefully acknowledged.[/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/10.1016/j.matchemphys.2017.08.044[/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]
