“…Electron and hole pairs are generated in the CNDs upon UV excitation (reaction 1) [35,36]. The photogenerated electrons reduced the surrounding AuCl 4 − (reaction 2), while the holes were scavenged by the alcohols (reactions 6) [37]. Au 0 atoms are generated after the fast disproportionation of Au 2 + (reaction 3) and the disproportionation of Au + and Au 2 + (reaction 4) [38].…”

“…Wet chemical processes involving reduction or thermal decomposition of metal salts are the most used synthesis techniques. [96] Wide variations of wet chemical processes include: polyol methods, [97] photochemical deposition, [98] electroless plating, [99] solvothermal, [100] hydrothermal, [101] sol-gel, [39] ion-implantation, [102] epitaxial growth, [103] etc. Vapour-gas phase processes, such as flame aerosol [104] and plasma-assisted deposition [105] are also commonly used.…”

Environmental context. Recent developments in nanotechnology have focussed towards innovation and usage of multifunctional and superior hybrid nanomaterials. Possible exposure of these novel nanohybrids can lead to unpredicted environmental fate, transport, transformation and toxicity scenarios. Environmentally relevant emerging properties and potential environmental implications of these newer materials need to be systematically studied to prevent harmful effects towards the aquatic environment and ecology.Abstract. Nanomaterial synthesis and modification for applications have progressed to a great extent in the last decades. Manipulation of the physicochemical properties of a material at the nanoscale has been extensively performed to produce materials for novel applications. Controlling the size, shape, surface functionality, etc. has been key to successful implementation of nanomaterials in multidimensional usage for electronics, optics, biomedicine, drug delivery and green fuel technology. Recently, a focus has been on the conjugation of two or more nanomaterials to achieve increased multifunctionality as well as creating opportunities for next generation materials with enhanced performance. With incremental production and potential usage of such nanohybrids come the concerns about their ecological and environmental effects, which will be dictated by their not-yet-understood physicochemical properties. While environmental implication studies concerning the single materials are yet to give an integrated mechanistic understanding and predictability of their environmental fate and transport, the importance of studying the novel nanohybrids with their multidimensional and complex behaviour in environmental and biological exposure systems are immense. This article critically reviews the literature of nanohybrids and identifies potential environmental uncertainties of these emerging 'horizon materials'.

“…One is to modify TiO 2 by surface deposition of noble metal clusters. 12 The second is to couple TiO 2 with other semiconductors which can trap the photogenerated e − or h + . 13 The third alternative way is to introduce defects into the TiO 2 lattice by doping with transition metal ions, e.g.…”

The composite photocatalyst, N-TiO 2 loaded with Ni 2 O 3 , was prepared by N 2 plasma treatment. X-ray diffraction, X-ray fluorescence, N 2 adsorption, UV-vis spectroscopy, photoluminescence, and X-ray photoelectron spectroscopy were used to characterize the prepared TiO 2 samples. The results indicated that the band gap energy was decreased obviously by nitrogen doping, whereas loading of Ni 2 O 3 did not influence the band gap and visible light absorption. The photocatalytic activities were tested in the degradation of 2,4,6-trichlorophenol (TCP) under visible light. The photocatalytic activity and stability of composite photocatalyst were much higher than that of catalyst modified with nitrogen or Ni 2 O 3 alone. The synergistic effect of doping nitrogen and Ni 2 O 3 over TiO 2 was investigated.
