Abstract
Sposób otrzymywania fotokatalitycznego anatazu, wykorzystujący proces kalcynacji, charakteryzuje się tym, że wysuszony amorficzny ditlenek tytanu impregnuje się roztworem soli niklu, suszy przez noc w temperaturze 100°C, uciera w moździerzu do postaci proszku i następnie kalcynuje w temperaturze do 700°C w atmosferze amoniaku. Jako sól niklu stosuje się azotan niklu (II), siarczan niklu (II), chlorek niklu (II) w ilości odpowiadającej zawartości niklu od 1% mas. do 10% masowych w stosunku do ditlenku tytanu. Kalcynację prowadzi się w atmosferze amoniaku przez 4 godziny w temperaturze poniżej przemiany anatazu w rutyl, to jest poniżej 700°C.The method of obtaining photocatalytic anatase, using the calcination process, is characterized by the fact that the dried amorphous titanium dioxide is impregnated with a nickel salt solution, dried overnight at 100 ° C, triturated in a mortar to form a powder and then calcined at up to 700 ° C in the atmosphere ammonia. The nickel salt used is nickel (II) nitrate, nickel (II) sulfate, and nickel (II) chloride in an amount corresponding to 1% by weight of nickel. up to 10% by mass in relation to titanium dioxide. Calcination is carried out in an ammonia atmosphere for 4 hours at a temperature below the conversion of anatase to rutile, i.e. below 700 ° C.
