摘要

•The MIL-101(Cr) robust chromium-terephthalate-based MOF was synthesized following a hydrothermal method.•The obtained MOF was characterized by XRD, SEM and nitrogen adsorption/adsorption isotherms (BET method).•The MOF was exploited as bulk component of a carbon paste electrode.•The obtained sensor showed high sensitivity and selectivity for the detection of sulfite ions and ascorbic acid.
