Accelerating the peroxidase-like activity of MoSe2 nanosheets at physiological pH by dextran modification

Abstract

Surface modification of MoSe₂via dextran during ultrasound exfoliation is demonstrated to be an efficient and easy strategy to accelerate the peroxidase-like catalytic activity of MoSe₂ nanosheets at neutral pH. The enhancement of catalytic activity is owing to the rich negative charges of dextran on the dextran-modified MoSe₂ nanosheets.
