Abstract
Sposób wytwarzania mezoporowatego TiO2 o strukturze anatazu, charakteryzuje się tym, że wysuszony ditlenek tytanu, który stanowi półprodukt do produkcji TiO2 metodą siarczanową, przemywa się wodą amoniakalną do uzyskania wartości pH w zakresie 6 - 7, następnie miesza się z 10 M roztworem KOH w stosunku wagowym 1:20, aż do czasu otrzymania jednolitej zawiesiny. Następnie tak otrzymany materiał podgrzewa się do temperatury 140°C przez 12, 24 lub 48 godzin, po czym po samoistnym ochłodzeniu do temperatury pokojowej zawiesinę kilkakrotnie przemywa się 0,1 M roztworem HCl nieustannie mieszając do uzyskania pH silnie kwaśnego, a następnie materiał przemywa się wodą destylowaną do uzyskania pH obojętnego. Tak otrzymany nanomateriał suszy się w piecu w atmosferze powietrza przez 2 godziny w temperaturze 350 °C, a następnie mieli.The method of producing mesoporous TiO2 with anatase structure is characterized by the fact that dried titanium dioxide, which is an intermediate for the production of TiO2 by the sulfate method, is washed with ammonia water until a pH value of 6 - 7 is obtained, then mixed with a 10 M KOH solution by weight 1:20, until obtaining a uniform suspension. Then the material so obtained is heated to 140 ° C for 12, 24 or 48 hours, after which after spontaneous cooling to room temperature the suspension is washed several times with 0.1 M HCl solution, stirring constantly to obtain a strongly acid pH, and then the material is washed with distilled water to obtain a neutral pH. The nanomaterial thus obtained is dried in an oven in an air atmosphere for 2 hours at 350 ° C. and then ground.
