Product Name
MnO2 nanosheet dispersion
Product Overview
Among the various types of manganese oxides and their derivatives, manganese dioxide is widely used in various fields due to its unique properties. Manganese dioxide nanoparticles have a variety of morphologies including four dimensions: zero-dimensional, one-dimensional, two-dimensional and three-dimensional. Manganese dioxide (MnO2) nanosheets are two-dimensional nanomaterials with redox activity, consisting of three atomic layers, whose structure is formed by one Mn atomic layer surrounded by two O atomic layers. The d-d jump of manganese ions in manganese dioxide nanosheets produces a broad absorption spectrum at 380 nm (200-600 nm) with a large molar extinction coefficient.
