In order to circumvent the usual nucleation of randomly distributed tiny metallic dots photodeposited on TiO2 nanoparticles (NPs) induced by conventional UV lamps, we propose synthesize well-controlled nanoheterodimers (NHDs) using lasers focused inside microfluidic reactors strongly photoactivate redox reactions active ions flowing along with in water solution. Since flux photons issued from a...

In this investigation, Ag@TiO2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial TiO2 nanoparticles (known as P25 TiO2) via photodeposition technique as clean and simple photochemical route. The synthesized Ag@TiO2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (DSSC) chiefly because, compared ...

Photocatalytic hydrogen (H2) production is a promising route for alternative energetics. Understanding structure–activity relationships crucial step towards the rational design of photocatalysts, which requires application operando spectroscopy under relevant working conditions. We performed an investigation on catalytic system during photodeposition Pt TiO2 and photostimulated H2 production, u...

Platinum (Pt) was selectively photodeposited onto zinc rhodium oxide (ZnRh2O4) to serve as a hydrogen (H2)-evolution photocatalyst in silver (Ag)-inserted ZnRh2O4 and bismuth vanadium (Bi4V2O11) solid-state (ZnRh2O4/Ag/Bi4V2O11). The amount of deposited Pt controlled by the photodeposition time generate Pt-loaded ZnRh2O4/Ag/Bi4V2O11 (Pt/ZnRh2O4/Ag/Bi4V2O11) containing up 0.17 wt % cocatalyst. p...

Modification of nickel sulfide cocatalysts is considered to be a promising approach for efficient enhancement the photocatalytic hydrogen production performance g-C3N4. Providing more NiS cocatalyst function as active sites g-C3N4 still highly desirable. To realize this goal, in work, facile sulfur-mediated photodeposition was developed. Specifically, photogenerated electrons excited by visible...
