Two-dimensional ultrathin MoS2-modified black Ti3+–TiO2 nanotubes for enhanced photocatalytic water splitting hydrogen production

New g-C3N4/GO/MoS2 composites as efficient photocatalyst for photocathodic protection of 304 stainless steel

“…The peaks located at 232.41 eV and 228.89 eV corresponded to Mo 3d 3/2 and Mo 3d 5/2 of Mo 4þ in MoS 2 , respectively (Zhou et al 2020). The peak at 235.65 eV was consistent with the Mo atoms exposed on the surface (Ou et al 2020). The weak peak at 226.03 eV can be ascribed to S 2À and Mo 4þ , which was the typical peak of MoS 2 (Bai et al 2018).…”

“…After adding GO, its E FB was negatively shifted to À1.01 eV. The negative shift of E FB increases the Fermi level of the material, which was more favorable for the transfer of photogenerated electrons (Liu et al 2018;Ou et al 2020). Through GO modification, the E FB of a photocatalyst was negatively shifted, which improved the transfer efficiency of photogenerated electrons and holes, thereby improving the photocathodic protection ability of the composites.…”

Prospects of Synthesized Magnetic TiO2-Based Membranes for Wastewater Treatment: A Review

“…This has inspired interest in making TiO2-engineered membranes for a variety of applications, including self-clean- Notwithstanding, IPMs have proven to be very promising in wastewater treatment settings, however, they are still limited in a large-scale application. In response, several organic, inorganic, metallic, and polymeric materials have been used as support materials in the fabrication of TiO 2 -based photocatalytic membrane reactors [25,26,53,70,87,88]. In contrast to immobilized TiO 2 membranes, TiO 2 nanofibers, nanowires, and nanotubes are also used to make pure TiO 2 photocatalytic membranes.…”

“…Engineered TiO 2 nanoparticles have various properties that allow them to bind specific pollutants or catalyze degradation reactions when deposited or embedded on membrane surfaces [26,88,90]. However, the nanomaterial loading, matrix content, particle dispersion, nanoscale phase size, shape and orientation, as well as interactions between the phases all affect the hybrid material's overall properties [26,90].…”

“…However, the nanomaterial loading, matrix content, particle dispersion, nanoscale phase size, shape and orientation, as well as interactions between the phases all affect the hybrid material's overall properties [26,90]. This has inspired interest in making TiO 2 -engineered membranes for a variety of applications, including self-cleaning, antimicrobial thin film coatings, photocatalysis, gas sensing and dye-sensitized solar cell nanofibers with well-controlled morphology [25,26,[87][88][89][90]. One-dimensional freestanding TiO 2 membrane reactors with various TiO 2 morphologies, such as nanotubes (NTs), nanofibers (NFs), and nanowires (NWs), have been developed to improve photocatalytic activity and reduce membrane fouling [31,45].…”
