“…Here sol-gel derived NP layer was coated with hydrothermally prepared NRs and this DSSC assembly exhibited an efficiency of 7.1%. Several NR/NP bilayered photoanode structures were fabricated later 151,155,156,[166][167][168][169][170] . These bilayer structures provided enhanced light scattering as well as increased surface area, which is finally reflected in their increased efficiencies (Fig.…”

“…Since titanates with a 1D morphology were extensively and successfully investigated, both for their electronic and optical properties [19][20][21][22][23] it is reasonable to assume that ammonia degradation on these materials can bring significant advancements for environmental preservation. In order to favour the ammonia photodegradation under solar light irradiation, pristine titanate nanorods were modified with iron for the improvement of light absorption and separation of photogenerated charges.…”

Sodium titanate nanorods were synthesized by a hydrothermal method and subsequently modified with an iron precursor. For comparison, Fe2O3 nanocubes were also obtained through a similar hydrothermal treatment. Pristine, Fe-modified nanorods and Fe2O3 nanocubes were suspended in diluted ammonia solutions (20 ppm) and exposed to ozone and simulated light irradiation. Ammonia abatement, together with the resulting nitrogen-containing products (NO3−), was monitored by ion chromatography measurements. The generation of reactive oxygen species (·OH and O2−) in the investigated materials and their photoelectrochemical behaviour were also investigated. Morphological and structural characterizations (SEM, XRD, XRF, UV–Vis, H2-TPR, NH3-TPD, PL, PZC) of the studied catalysts were correlated with their activity for ammonia degradation with ozone- and photo-assisted oxidation. An increase in ammonia conversion and a decreasing amount of NO3− were achieved by combining the above-mentioned processes.

“…Titanium dioxide nanoparticles (TiO 2 NPs) are one of the most important transition-metal oxides that have been extensively applied for photocatalysts, [1,2] supercapacitors, [3] dye-sensitized solar cells, [4] and biomedicine [5] because of their chemical stability, relatively high photocatalytic activity, nontoxicity, and low cost. As is well known, the performance of TiO 2 is strongly dependent on morphology, size, and crystallinity.…”

TiO 2 nanoparticles (NPs) were prepared by cathode glow discharge electrolysis in sodium fluoride solution, in which cetyltrimethyl ammonium bromide (CTAB) acted as a stabilizer, and a Ti foil and a Pt needlepoint served as the anode and the cathode, respectively. The structure, component, and morphology of TiO 2 NPs were characterized. A possible preparation mechanism was proposed. In addition, the photocatalytic performance of TiO 2 NPs was assessed through the degradation of methylene blue (MB). The results showed that TiO 2 NPs with 12.7 nm particle size could be prepared at 500 V discharge voltage. CTAB, as a stabilizer, can diminish the agglomeration. The photocatalytic property of TiO 2 NPs for the degradation of MB with 0.15% CTAB is markedly superior to that of TiO 2 NPs without adding CTAB and commercial TiO 2 NPs (P25).
