Visual colorimetric detection of tin(II) and nitrite using a molybdenum oxide nanomaterial-based three-input logic gate

We report a molybdenum oxide (MoO 3 ) nanomaterial-based three-input logic gate that uses Sn 2+ , NO 2 − , and H + ions as inputs. Under acidic conditions, Sn 2+ is able to reduce MoO 3 nanosheets, generating oxygen-vacancy-rich MoO 3− x nanomaterials along with strong localized surface plasmon reso...
