Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania hybrydowych materiałów węglowo - azotowych o rozwiniętej strukturze porowatej. Sposób ten charakteryzuje się tym, że substancją organiczną jest L - lizyna, która jest mieszana z surowcem nieorganicznym - węglanami metali alkalicznych i/lub metali ziem alkalicznych, rozdrobnionych do ziaren o rozmiarach nanometrycznych, w stosunku wagowym (L - lizyna : węglan) od 4 : 1 do 1 : 1 w przeliczeniu na suchą masę, następnie homogenizowana mechanicznie, a uzyskana masa podgrzewana jest z szybkością od 5°C/min do 15°C/min w atmosferze gazu obojętnego, przy czym termolizę w warunkach beztlenowych prowadzi się w szerokim zakresie temperatur od 600°C do 900°C przez okres od 60 minut do 150 minut, po czym schładza się otrzymany surowy HMW - A do temperatury około 50°C, utrzymując atmosferę beztlenową, po czym uzyskany produkt w postaci nieporowatej, ale zawierającej głównie węgiel i azot, poddaje się działaniu mocnego kwasu nieorganicznego, w celu usunięcia składnika nieorganicznego, a wytrawiony kwasem produkt płucze się wodą demineralizowaną do uzyskania wartości pH odcieku w zakresie od 6 do 7, po czym suszy przez okres od 12 godzin do 24 godzin w temperaturze od 70°C do 100°C.The subject of the application is a method of obtaining hybrid carbon-nitrogen materials with a developed porous structure. This method is characterized by the fact that the organic substance is L - lysine, which is mixed with the inorganic raw material - alkali metal and / or alkaline earth metal carbonates, crushed to grains of nanometric size, in a weight ratio (L - lysine: carbonate) from 4 : 1 to 1: 1 on a dry basis, then mechanically homogenized, and the obtained mass is heated at a rate of 5 ° C / min to 15 ° C / min in an inert gas atmosphere, with thermolysis under anaerobic conditions being carried out in a broad temperature range from 600 ° C to 900 ° C for a period of 60 minutes to 150 minutes, after which the obtained raw HMW - A is cooled to a temperature of about 50 ° C, maintaining an anaerobic atmosphere, then the obtained product in a non-porous form, but containing mainly carbon and nitrogen are treated with strong inorganic acid to remove the inorganic component, and the acid-etched product is rinsed with demineralized water to obtain a pH of the effluent in the range of 6 to 7, and then dried for a period of 12 hours to 24 hours at a temperature of 70 ° C to 100 ° C.
