Abstract
Ujawniono płatki grafenu modyfikowane powierzchniowo nanocząstkami kompozytowymi dwutlenek tlenek tytanu-metal szlachetny, a także sposób otrzymywania modyfikowanych płatków grafenu, który polega na tym, że do płatków grafenu lub tlenku grafenu zdyspergowanych w rozpuszczalniku organicznym wybranym z grupy węglowodory alifatyczne zawierające od 3 do 9 atomów węgla wprowadza się związek tytanu o wzorze ogólnym Ti(OR)n, gdzie n=3-4, oraz i/lub (R-O)n-Ti-(O-R')m, gdzie n,m=2, oraz i/lub (R-O-O-R)n-Ti-(O-R')m, gdzie n,m=2, oraz i/lub (TiO)(R-O-R)n, gdzie n=2, oraz i/lub (R-O-R'-NH2)n-Ti-(OH)m, gdzie n,m=2, w którym R, R' oznacza podstawnik alkilowy zawierający od 1 do 9 atomów węgla oraz związek metalu szlachetnego o wzorze ogólnym: MeRx, w którym R oznacza podstawnik alkilowy zawierający od 1 do 9 atomów węgla lub podstawnik nieorganiczny grupy V, VI, VII (węglany, wodorotlenki, chlorki, siarczki, fluorki, jodki, azotany, tiocyjaniany) lub mieszaninę tych związków. Następnie miesza się dalej w obecności suchego lub wilgotnego powietrza, usuwa rozpuszczalnik, a pozostałość po wysuszeniu poddaje się rozkładowi termicznemu w obecności powietrza, w temperaturze od 200 do 700°C. Stężenie związku tytanu w rozpuszczalniku organicznym zawiera się w przedziale od 0,001 do 10 mol/l a stężenie związku metalu szlachetnego w rozpuszczalniku organicznym zawiera się w przedziale od 0,001 do 10 mol/l.Graphene flakes modified with nanoparticles composite titanium dioxide-noble metal are disclosed, as well as the method of obtaining modified graphene flakes, which consists in the fact that graphene flakes or graphene oxide dispersed in an organic solvent selected from the group of aliphatic hydrocarbons containing from 3 to 9 carbon atoms a titanium compound with the general formula Ti (OR) n, where n = 3-4, and and / or (RO) n-Ti- (O-R ') m, where n, m = 2, and and / or (ROOR) n-Ti- (O-R ') m, where n, m = 2, and and / or (TiO) (ROR) n, where n = 2, and and / or (RO-R'-NH2 ) n-Ti- (OH) m, where n, m = 2, wherein R, R 'is an alkyl substituent containing from 1 to 9 carbon atoms and a noble metal compound having the general formula: MeRx, in which R is an alkyl substituent from 1 to 9 carbon atoms or inorganic substituent groups V, VI, VII (carbonates, hydroxides, chlorides, sulfides, fluorides, iodides, nitrates, thiocyanates) or a mixture of these compounds optional. It is then stirred further in the presence of dry or moist air, the solvent is removed, and the residue after drying is subjected to thermal decomposition in the presence of air at a temperature of 200 to 700 ° C. The concentration of titanium compound in the organic solvent is in the range of 0.001 to 10 mol / l and the concentration of the precious metal compound in the organic solvent is in the range of 0.001 to 10 mol / l.
