Sandwich structured graphene modified TiO2 mesoporous single crystals (GR-MSCs) were obtained by using the graphene embedded silica spheres as the hard template, via a hydrothermal treatment. The selective photocatalysis of TiO2 can be achieved by controlling the location of graphene in TiO2 mesoporous single crystals. The sandwich structured graphene-TiO2 composite has a photooxidation surface...

The SrTiO3 modified rutile TiO2 composite nanofibers were synthesized by a simple electrospinning technique. The result of XRD, SEM and TEM indicate that the SrTiO3/TiO2 heterojuction has been prepared successfully. Compared with the TiO2 and SrTiO3, the photocatalytic activity of the SrTiO3/TiO2 (rutile) for the degradation of methyl orange exhibits an obvious enhancement under UV illumination...

In order to move from a carbon-based energy system more sustainable one, focus is put on liquid organic hydrogen carrier (LOHC) systems for CO2-free storage and release. this study sulfur as dopant the Pt/TiO2 catalyst was identified be selective poison resulting in high performing catalysts dehydrogenation experiments with LOHC perhydro dibenzyltoluene/dibenzyltoluene (H18-DBT/H0-DBT). The S–P...

Integrating plasmon resonant nanostructures with photocatalytic semiconductors shows great promise for high efficiency photocatalytic water splitting. However, the electrochemical instability of most III-V semiconductors severely limits their applicability in photocatalysis. In this work, we passivate p-type GaP with a thin layer of n-type TiO2 using atomic layer deposition. The TiO2 passivatio...

To take advantage of the synergistic effects of Pt and Zr, a kind of Zr-doped, Pt-modified aluminide coating has been prepared by a hybrid process, first electroplating a Pt layer and then co-depositing Zr and Al elements by an above-the-pack process. The microstructure and isothermal oxidation behavior of the coating has been studied, using a Pt-modified aluminide coating as a reference. Resul...

The photo-Kolbe reaction (electro-oxidation of acetate) on TiO2 in aqueous solution has been studied by means of a rotating ring-disk electrode (RRDE) with a TiO2 disk and Pt ring. The oxidation of acetate competes very efficiently with water for photogenerated holes on the illuminated n-TiO2 disk as shown by a decrease in the collection efficiency for oxygen reduction. No oxidation product of ...

Oxygen vacancies-enriched black TiO2 is one promising support for enhancing hydrogen evolution reaction (HER). Herein, oxygen vacancies enriched supported sub-nanometer Pt clusters (Pt/TiO2-OV) with metal interactions designed through solvent-free microwave and following low-temperature electroless approach the first time. High-temperature strong reductants are not required then can avoid aggre...

A hybrid strategy for solar water splitting is exploited here based on a dye-sensitized photoelectrosynthesis cell (DSPEC) with a mesoporous SnO2/TiO2 core/shell nanostructured electrode derivatized with a surface-bound Ru(II) polypyridyl-based chromophore-catalyst assembly. The assembly, [(4,4'-(PO3H2)2bpy)2Ru(4-Mebpy-4'-bimpy)Ru(tpy)(OH2)](4+) ([Ru(a) (II)-Ru(b) (II)-OH2](4+), combines both a...

Nanotube titanic acid (NTA) network film has a porous structure and large BET surface area, which lead them to possessing high utilization of the incident light and strong adsorption ability. We used NTA as the precursor to fabricate a TiO2/ SrTiO3 heterojunction film by the hydrothermal method. In the process of the reaction, part of NTA reacted with SrCl2 to form SrTiO3 nanocubes, and the rem...
