Hybrid nanocomposites with spatial structure, method for producing them, nanostructural sensors that contain hybrid nanocomposites as anode material on the working electrode, and application of those hybrid nanocomposites

摘要

The notification concerns spatial hybrid nanocomposites comprising ultra thin graphite nitrogen nano -layers of carbon dioxide (g -C3N4),mixed with a conductive material constituting nanostructures of only base transition metals or fixed solutions of their mixtures.The notification also concerns the way in which these nanocomposites are produced, in which the pH of the aqueous solution of urea (CO (NH2)2) is first adjusted to range 4,0 -5,5 with nitric acid (HNO3),The aqueous solution of urea (CO (NH2)2) is then heated at the heating speed of 2 -5 -min -1 with a two -dimensional graphite (2D) carbon nitrogen (g -C3N4) which is thenbe modified by aqueous solutions of salts of base metals or mixtures of their fixed solutions,where these salts are used in the form of hydrogenated nitrogen salts (V) stabilised sodium borohydrate (NaBH4).The scope of the notification is also nanostructural sensors containing these nanocomposites and the use of nanocomposites,including as sensing elements in the function of anode catalysts for the electrocatalytic oxidation process of C1 -C4 organic compounds in low -temperature fuel cells.
