Jute stick extract assisted hydrothermal synthesis of zinc oxide nanoflakes and their enhanced photocatalytic and antibacterial efficacy

•Hot extraction of jute stick.•A green hydrothermal approach to synthesize ZnO nanoflakes using jute stick extract.•Prepared jute extrcact assisted ZnO nanoflakes showed a significant dye degradation.•98 % efficiency in MB degradation was calcualted after 8 h of UV light irradiation.•Prepared jute supported ZnO exhibited 19 mm of zone inhibition against E. coli.
