“…7. When the relative humidity was increased from 30% to 50%, NO removal (%) was MoO 6 as catalysts in the oxidative dehydrogenation of C 4 raffinate-3 [25] and the partial oxidation of propylene to acrolein [26]. In the later work, the authors proposed a remote control mechanism, in which oxygen species formed on the Bi 2 MoO 6 surface migrate onto the surface of Bi 2 Mo 3 O 12 to create active sites.…”

“…For the A-5 sample the amount of removed NO during light illumination for 1200 s was 0.31 mmol, and the generated NO 2 was 0.18 mmol, which was 58.1% of the removed NO. The rest of the removed NO (0.13 mmol) is inferred to be oxidized into NO 3 À or HNO 3 and then fixed on the film surface, 23,24) or directly decomposed into N 2 , O 2 , and N 2 O. 25) Figure 9(b) shows the amount of removed NO (QNO) and the amount of generated NO 2 (QNO 2 ) under the (UV + visible) light for various samples.…”

Pale yellow N-doped TiO x films on the glass substrate were prepared by RF magnetron reactive sputtering of Ti target in a mixed gas of argon and dry air. The characteristics of the N-doped TiO x films were studied by SEM, XRD, UV-Vis spectrophotometer and XPS. The photocatalytic ability was evaluated by degradation of NO gas. The air flow ratio has a significant effect on the produced phase and the bonding states of Ti, O and N, resulting in the variation of the optical property and photocatalytic ability. The large amount of N atoms doped and oxygen deficiency are detrimental for photocatalysis, and N bonding states may not be the major contributing factor for the photocatalysis. It is suggested that the coexistence of N 2 gas with O 2 gas shifts the TiO 2 formation boundary towards the low oxygen concentration, which leads to various N (N oxide) doping states on N-doped TiO x film.

a b s t r a c tPolystyrene cross-linked divinyl benzene (PS-co-DVB) microspheres were used as an organic template in order to synthesize photocatalytic TiO 2 microspheres and microbowls. Photocatalytic activity of the microbowl surfaces were demonstrated both in the gas phase via photocatalytic NO(g) oxidation by O 2 (g) as well as in the liquid phase via Rhodamine B degradation. Thermal degradation mechanism of the polymer template and its direct influence on the TiO 2 crystal structure, surface morphology, composition, specific surface area and the gas/liquid phase photocatalytic activity data were discussed in detail. With increasing calcination temperatures, spherical polymer template first undergoes a glass transition, covering the TiO 2 film, followed by the complete decomposition of the organic template to yield TiO 2 exposed microbowl structures. TiO 2 microbowl systems calcined at 600 • C yielded the highest per-site basis photocatalytic activity. Crystallographic and electronic properties of the TiO 2 microsphere surfaces as well as their surface area play a crucial role in their ultimate photocatalytic activity. It was demonstrated that the polymer microsphere templated TiO 2 photocatalysts presented in the current work offer a promising and a versatile synthetic platform for photocatalytic DeNO x applications for air purification technologies.
