  - APPLIED CATALYSIS B-ENVIRONMENTAL - Year 2008

  Przygotowano serię fotokatalizatorów w postaci tlenku tytanu (IV) kalcynowanych w różnych temperaturach od 350 do 750˚C. Charakterystyka fotokatalizatorów za pomocą metod XRD, UV-Vis/DRS, FTIR, XPS, BET oraz BJH wykazała, że próbka TiO2 aktywna w świetle widzialnym posiadała strukturę anatazu, powierzchnię właściwą ok. 200 m2/g, absorbowała światło o długości fali λ>400 nm oraz zawierała 10,1 % at. węgla (wiązanie C-C). Aktywność...

  - APPLIED CATALYSIS B-ENVIRONMENTAL - Year 2007

  Otrzymano TiO2 domieszkowany borem i wyznaczono jego aktywność fotokatalityczną w zakresie światła UV i Vis. Katalizatory otrzymano metodą zol-żel lub poprzez ucieranie dwutlenku tytanu z prekursorami B. Jako źródło boru zastosowano kwas borowy lub ester trietylowy kwasu borowego. Fotoaktywność próbek badano w reakcji degradacji fenolu (Co = 0,21 mmol/dm3 ) w zakresie światła Vis lub UV. Obecność węgla i boru we wszystkich przygotowanych...

  Metodą elektroabsorpcji (EA) badano stany wzbudzenia elektronowego w próżniowo naparowanych warstwach diamin (TPD, TAPC) i dendrymeru aminowego m-MTDATA. Widma EA amin złożonych porównano z widmem monomeru trifenylaminy (TPA). Kształt widm EA świadczy o obecności zdegenerowanych i quasi-zdegenerowanych stanów elektronowych.

  Because of the tremendous structural diversityof ionic liquids (ILs), simple transfer of observations performed for one IL used for IL-TiO2 preparation on different samples is not possible. Therefore, four ionic liquids, all containing distinct nitrogen-bearing organic cations (pyridinium, pyrrolidinium, ammonium, imidazolium), were used for the first time for the preparation of IL-TiO2 composites. The role of the individual IL...
