P25 titanium dioxide coated magnetic particles: Preparation, characterization and photocatalytic activity

Photocatalytic activity of TiO2, ZnO and Nb2O5 applied to degradation of textile wastewater

“…Ti-500 showed higher specific surface area than Zn-500, whose specific surface area was 7.42 m 2 g -1 , close to reported by Velmurugan et al [32]. The specific area obtained for TiO2-P25 was 60.55 m 2 g -1 close to found by other authors [25,33,34]. Nb-500 showed high specific area, total pore and micropore volume.…”

“…Nb2O5 as well as TiO2, presents good chemical stability, non toxicity and commercial availability [24]. However, widespread use of TiO2 has become uneconomical for water treatment operations on large scale [12] mainly due to the need of UV radiation, reactor design and additional separation steps requirement [25]. Thereby interest has been drawn towards the search for suitable alternatives to TiO2.…”

Electrospun silk fibroin/TiO2 mats. Preparation, characterization and efficiency for the photocatalytic solar treatment of pesticide polluted water

“…The presence of Ti in water during the irradiation time was found to be negligible according to previous papers. 4,26,28 Reusability study of SF/TiO 2 was done to ensure its applicability as recycled catalyst. The photooxidation of boscalid, pyraclostrobin, hexythiazox and trioxystrobin was performed for 720 min with sampling every 180 min (4 cycles).…”

Experimental Design and Optimization of Triclosan and 2.8-Diclorodibenzeno-p-dioxina Degradation by the Fe/Nb2O5/UV System

“…The use of niobium pentoxide (Nb 2 O 5 ) as a semiconductor for application in heterogeneous photocatalysis has few literature references. This compound has chemical characteristics of low toxicity and band gap (3.4 eV), which is very similar to TiO 2 [14,15]. It is a stable semiconductor and insoluble in water, which can be attacked only by concentrated hydrofluoric acid.…”
