Copper metal-organic framework nanocrystal for plane effect nonenzymatic electro-catalytic activity of glucose

This work describes the first demonstration of nanocrystal plane dependent nonenzymatic electro-catalytic glucose activity of [Cu3(btc)2] nanocrystals with different shapes (nanocube, truncated cube, cuboctahedron, and octahedron). From electrochemical results, the obtained [Cu3(btc)2] nanocube modi...

Description
Summary:This work describes the first demonstration of nanocrystal plane dependent nonenzymatic electro-catalytic glucose activity of [Cu3(btc)2] nanocrystals with different shapes (nanocube, truncated cube, cuboctahedron, and octahedron). From electrochemical results, the obtained [Cu3(btc)2] nanocube modified electrode shows the best nonenzymatic electro-catalytic glucose activity. Interestingly, decreasing the {100} crystal planes from cubes to octahedra, changes the nonenzymatic electro-catalytic activity from highly sensitive to general.
