Dual-scale TiO

Surfaces that have unique wettabilities and are simultaneously superhydrophobic with water contact angles > 150°, and superoleophilic with oil contact angles < 5°, are of critical importance in the oil/solvent–water separation field. This work details the facile preparation of highly efficient oil–water separation

Preparation of a Novel Ternary Composite of TiO

Abstract. Inhibiting the recombination of electron–hole pairs of TiO 2-based photocatalysts to enhance the photocatalytic activities received continuous attention in the past decades.Herein, a ternary composite of TiO 2 /UiO-66-NH 2 /graphene oxide was designed to facilitate the photoelectrons transfer. When –NH 2 was grafted, graphene …

Facile synthesis of superhydrophobic MS/TiO

After the oil–water separation test, the MS/TiO 2 /PDMS sponge was recycled more than 25 times. The super oil adsorption capacity of the MS/TiO 2 /PDMS sponge after hydrophobicity modification is determined by the double factors of multistage structural pore and hydrophobic pore wall. These conclusions suggest that by changing …

Nano TiO 2 -Based Smart Superhydrophilic Self-Cleaning …

2. Self-cleaning action of TiO 2 as photocatalyst. Once a metal oxide semiconductor is irradiated with an energy source that is higher than its band gap (3.2 eV) [] leads to the absorption of photons and excitation of an electron (e−) in which way generate an electron–hole pair, with the hole (h+) left behind in the valence band.These …

Structure and photocatalytic performances of glass/SnO

TiO 2-based heterojunction nano-thin films are competitive photocatalysts for water pollution treatment due to their abundant availability, non-toxicity, and rapid separation of photogenerated charge carriers.Moreover, the layer thickness, as a vital factor influencing the photocatalytic properties of TiO 2-based heterojunction nano-thin …

Visible-light-responsive reduced graphene oxide/g-C 3 N 4 /TiO …

The FE-SEM images displayed the morphologies of the as-prepared nanocoatings.The TiO 2 nanocoating surface had anisotropic nanowire-like structures with diameters from 20 to 60 nm. For the CN/TO nanocomposite, there was no obvious morphology change after g-C 3 N 4 deposition. This indicated that a conformal g-C 3 N 4 coating was formed on the TiO 2 …

Enhanced charge separation and oxidation kinetics by …

The charge separation and oxidation kinetics efficiencies of the optimized Pt/H:TiO 2 were improved to 62.2 and 39.9% compared with TiO 2 (54.2 and 27.6%) at 1.0 V versus RHE, and the electron transport time was reduced ~ 20% by analyze the CIMPS. Based on the mechanism analysis, the simultaneously enhanced separation and …

Preparation and Characterization of Reduced Graphene Oxide /TiO

Synthesis of GO and rGO/TiO 2 Nanocomposites. GO was synthesized first by natural graphite powder via a modified Hummer's method (Hummers and Offeman, 1958; Ding et al., 2019).In brief, 5 g graphite was uniformly dispersed in 300 ml of concentrated H 2 SO 4 in a round-bottom flask, stirring for 5 min. After that, 4.2 g K 2 S 2 O 8 and 6.2 g …

Furthermore, the coated fabric still maintained 98% separation efficiency after 16 cycles. Moreover, it offered good high temperature …

Crystal Facet Engineering of TiO

Two types of BiVO 4 /TiO 2 heterostructure photoanodes comprising TiO 2 nanorods (NRs) and TiO 2 nanoflowers (NFs) with different (001) and (110) crystal facets, respectively, were designed.. The higher photoactivity of BiVO 4 /TiO 2 NFs than BiVO 4 /TiO 2 NRs was attributed to the improvement of charge separation by the TiO 2 NFs.. …
