Efficient visible light-induced H2 production by Au@CdS/TiO2 nanofibers: Synergistic effect of core–shell structured Au@CdS and densely packed TiO2 nanoparticles

Comparative activity of CdS nanofibers superficially modified by Au, Cu, and Ni nanoparticles as co-catalysts for photocatalytic hydrogen production under visible light

“…Different modifications have been proposed for this photocatalysts to improve its performance. As has been reported, the formation of a heterojunction using TiO 2 , the deposition of noble metals such as Pt on its surface, non‐noble metals such as copper and nickel; and recently the formation of Au@CdS core shell nanoparticles on TiO 2 have been evaluated for hydrogen production under visible light . Among the efforts to improve the photocatalytic activity of semiconductors, several strategies to increase the response under visible light and to avoid the recombination of the h + e − pair, have been used.…”

Fabrication of Cu2O/Au/BiPO4 Z-scheme photocatalyst to improve the photocatalytic activity under solar light

“…Fig. 4(c) shows the XPS spectrum of Au 4f with the characteristic peaks at 84.1 eV and 87.7 eV of Au 0, confirming the existence of Au 0 in the composite [7,11]. In Fig.…”

“…It could be clearly seen that the pure BiPO 4 absorb solar energy with a wavelength shorter than 300 nm. However, as the introduction of Au, BiPO 4 exhibited an extra absorption peak at the visible region (about 540 nm), which could be attributed to the localized surface plasmon resonance (LSPR) effect of the Au nanoparticles (regarded as a process of electron fluctuation) [11]. The electrons in Au 6sp band could obtain energy and transfer to the higher energy level in its orbital equipped with the similar gaseous behavior of the fluctuation in the stimulation of external light [26].…”

“…their combination with noble metal nanoparticles, such as Pd, Pt, Ag and Au [7]. Some of these metals such as Au, can extend absorption wavelength range due to the presence of localized surface plasmon resonance leading to energy transfer from the metal to the semiconductor [8][9][10][11]. In a recent work, it was proposed that noble metals at the semiconductor surface may act as recombination sites [12].…”

Synthesis and solar light catalytic properties of titania–cadmium sulfide hybrid nanostructures

“…Moreover, acetaldehyde is an important intermediate in organic syntheses for the production of acetic acid, acetic anhydride and many other products [19,20]. Usually, CdS-TiO 2 nanostructures are used for photocatalytic hydrogen production [21] and liquid phase photooxidation of benzyl alcohols [22][23][24]. The selective gas phase photooxidation of ethanol to acetaldehyde was carried out under UV-light only [18,20].…”
