“…This is mainly attributed to the 1-D tubular structure and large BET surface area of TNT, where 1-D tubular structure facilitated fast electrons transfer due to reduced grain boundary, 36 and large surface area provided more active sites for reaction. 12 Excellent activity of Cu-TNT-A affirmed the simple but efficient characters of adsorption-dry process.…”

Cu species was introduced into TiO2 nanotube prepared by hydrothermal method via a facile adsorption-dry process. The fabricated sample exhibited excellent H2 generation activity (76.3 mmol h(-1) g(-1)(catalyst)), which was higher than most of the reported Cu incorporated TiO2 samples, even superior to some Pt/Pd/Au/Ni incorporated TiO2. Compared to wet impregnation and in-situ photo-deposition methods, the facile adsorption-dry process was much simpler but more efficient to introduce Cu species into TiO2 for H2 production. To fully understand the adsorption-dry process, characterizations of the samples were carried out by high-resolution transmission electron microscope, X-ray diffractometer, energy dispersive X-ray spectrometer, BET surface area analysis, UV-visible spectrophotometer and X-ray photoelectron spectroscopy. It was found that the facile adsorption-dry process could well maintain the morphology of TiO2 support, for instance, 1-D tubular structure and large BET surface area of TiO2 nanotube; moreover, the introduced Cu species was highly dispersed and intensively bonded with TiO2. All of these contributed to the high H2 generation activity.

“…Different studies have examined the use of hybrid metal–semiconductor nanoparticles to reroute solar energy to this reaction 163. 177–179 The aim of most studies is the use of visible light for this reaction, requiring efficient absorption in the visible range by the semiconductor. This goal might be realized by constructing nanohybrid z‐scheme systems, which involves two‐step photon excitation and charge separation,180 and complex hybrid systems that allow good light absorbance and charge separation 181.…”

One key goal of nanocrystal research is the development of experimental methods to selectively control the composition and shape of nanocrystals over a wide range of material combinations. The ability to selectively arrange nanosized domains of metallic, semiconducting, and magnetic materials into a single hybrid nanoparticle offers an intriguing route to engineer nanomaterials with multiple functionalities or the enhanced properties of one domain. In this Review, we focus on recent strategies used to create semiconductor-metal hybrid nanoparticles, present the emergent properties of these multicomponent materials, and discuss their potential applicability in different technologies.

“…Although various noble metals [9,12], transition metal ions [13], and non-metal [14,15] doped TiO 2 nanotubes have been successfully prepared, there have been a few reports on synthesizing rare-earth metal doped TiO 2 nanotubes. According to our knowledge, there are reports only about rare-earth metal europium [16], lanthanum [17] and neodymium [18] doped TiO 2 nanotubes.…”
