Azo dyes decomposition on new nitrogen-modified anatase TiO2 with high adsorptivity

Reduction of CO2 by adsorption and reaction on surface of TiO2-nitrogen modified photocatalyst

“…A comparison of base-TiO 2 with TiO 2 /N-100 revealed a presence of two additional narrow bands at 1440 cm À1 and 1536 cm À1 . The former one is attributed to the ammonium (NH 4 + ) group while the latter could be assigned to either NH 2 or NO 2 [27,28] and NO groups [29,30].…”

Effect of hydroxyl group of carboxylic acids on the adsorption of Acid Red G and Methylene Blue on TiO2

“…Recently, many studies have focused on the adsorption of TiO 2 for its low cost, simple preparation, good stability and non-toxic nature [6][7][8][9][10][11]. Belessi et al [7] claimed that the TiO 2 they prepared had the adsorption capacity of 86.96 mg/g for Reactive Red 195.…”

Cellulose-TiO2 nanocomposite with enhanced UV–Vis light absorption

“…(Randorn et al 2004), which may suggest that nitrogen was not only successfully incorporated into the structural lattice but also bounded with the surface of TiO 2 . A weak bond at 1,536 cm -1 in TiO 2 /N sample (named as 4) could be assigned to either NH 2 or NO 2 and NO groups as it was described by Janus et al (2009). As it can be seen after mixing of cellulose with TiO 2 /N material the bond assigned to Ti 4?…”

“…As it can be seen cellulose mixed with 10 wt% of TiO 2 /N catalyst absorbs light stronger than crystalline cellulose, increases absorption under UV to complete 100 % as well as under visible range (400-800 nm) up to 50 %. This could be assigned to the presence of nitrogen in the lattice of TiO 2 (Wawrzyniak and Morawski 2006;Janus et al 2009) and also because of the yellow colour of new composite. The colour of obtained nanocomposite was noted to be more intensive than precipitated cellulose.…”
