Abstract

Zgłoszenie dotyczy nanokompozytów hybrydowych o przestrzennej strukturze, obejmujących ultracienkie nanowarstwy grafitowego azotku węgla (g-C3N4), domieszkowanego materiałem przewodzącym stanowiącym nanostruktury wyłącznie nieszlachetnych metali przejściowych lub roztworów stałych ich mieszanin. Zgłoszenie dotyczy również sposobu wytwarzania wspomnianych nanokompozytów, w którym najpierw pH wodnego roztworu mocznika (CO(NH2)2) dostosowuje się do zakresu 4,0 - 5,5 przy pomocy kwasu azotowego (HNO3), następnie wygrzewa się wodny roztwór mocznika (CO(NH2)2) przy zachowaniu szybkości grzania w zakresie 2°-5° min-1 z uzyskaniem grafitowego dwuwymiarowego (2D) azotku węgla (g-C3N4) który następnie poddaje się modyfikacji wodnymi roztworami soli nieszlachetnych metali przejściowych lub mieszanin ich roztworów stałych, przy czym sole te stosuje się w postaci uwodnionych soli azotowych (V) stabilizowanych borowodorkicm sodu (NaBH4). Przedmiotem zgłoszenia są także nanostrukturalne czujniki zawierające wspomniane nanokompozyty oraz zastosowanie nanokompozytów, w tym jako elementów czujników w funkcji katalizatorów anodowych do procesu elektrokatalitycznego utleniania związków organicznych C1-C4 w ogniwach paliwowych niskotemperaturowych.The application concerns hybrid nanocomposites with a spatial structure, including ultra-thin nanowayers of graphite carbon nitride (g-C3N4) doped with a conductive material that is nanostructures of only non-noble transition metals or solid solutions of mixtures thereof. The application also relates to a method of producing the said nanocomposites, in which first the pH of the aqueous urea solution (CO (NH2) 2) is adjusted to the range of 4.0 - 5.5 with nitric acid (HNO3), then the aqueous urea solution (CO ( NH2) 2) while maintaining the heating rate in the range of 2 ° -5 ° min-1 to obtain graphite two-dimensional (2D) carbon nitride (g-C3N4) which is then subjected to modification with aqueous solutions of base salts of transition metals or mixtures of their solid solutions, with these salts are used in the form of hydrated nitrogen (V) salts stabilized with sodium borohydride (NaBH4). The subject of the application are also nanostructured sensors containing the mentioned nanocomposites and the use of nanocomposites, including as sensor elements as anode catalysts for the process of electrocatalytic oxidation of C1-C4 organic compounds in low-temperature fuel cells.
