Extended study on the synthesis of amorphous titanium phosphates with tailored sorption properties

Sorption performances of TiO(OH)(H2PO4)·H2O in synthetic and mine waters

“…3) reported for TiP-IE in various studies. 4,15,16,30,37,38 It has been shown that the conversion of aTiP into its alkaline form could result in a Na + uptake from 2. Likewise, the formation of three phases in the case of TiP1 is most likely to happen: TiO(OH)(H 2 PO 4 ), TiO(OH)(HNaPO 4 ) and TiO(OH)(Na 2 PO 4 ) and the latter one would start forming aer pH > 6.…”

Hierarchical flower-like titanium phosphate derived from H-titanate nanotubes for photocatalysis

“…The broad band around 3400 cm -1 is due to overlapping asymmetric and symmetric-OH stretching vibrations of adsorbed water molecules, and the band at 1615-1650 cm -1 is generally related to the -OH bending vibration of adsorbed water, such as HOH bend and H 3 O ? [14]. For the TiP-F sample, the characteristic antisymmetric/symmetric stretching vibration peaks of P-O and P-OH groups [40] at 1000-1280 cm -1 are present.…”

“…The peak at 570 cm -1 might be associated with PO 4 3- [15], and the bands at 768 and 915 cm -1 are assigned to the stretching mode of Ti-O bond in the Ti-O-P framework [15,25]. The bands at 1045 and 1132 cm -1 may be assigned to the O-P stretching mode of HPO 4 2-groups [14,32]. The decreased peak intensity at 464 cm -1 with the increased calcination temperature reveals its relevance to (PO 3 ) deformation mode [41].…”

“…7b, the FT-IR spectra of Ti-NT point to [14,38,39]. The broad band around 3400 cm -1 is due to overlapping asymmetric and symmetric-OH stretching vibrations of adsorbed water molecules, and the band at 1615-1650 cm -1 is generally related to the -OH bending vibration of adsorbed water, such as HOH bend and H 3 O ?…”

“…Iron titanium phosphates have been used as the electrode materials for hydrogen production [10]. Among them, titanium phosphate (TiP) materials have attracted widespread attention for their applications on electrode [11,12], cosmetics [13], and adsorbents [14]. But there are very limited studies on the photocatalytic properties of TiP materials.…”
