“…The ALT was employed to enhance the interaction between Ti and Cu NPs in a suspension solution to obtain a stable composite with an improved microstructure with a developed framework to reduce the agglomeration phenomena and to achieve the homogeneous distribution of Cu species on the titania surface. We used focused laser beam, the ALT provided plasma locally generated inside the processed colloidal mixture, which additionally stimulated efficient interactions between particles and formation of nanoscale composite. , The samples prepared with the ALT were designated as X Cu-dark TiO 2 h ν ( X = 0.5 or 1.0 wt % of Cu). Model dark TiO 2 sample prepared with the ALT and without Cu addition was designated as dark TiO 2 h ν.…”

In the present work, the highly effective nanoscale Cumodified dark TiO 2 photocatalysts for hydrogen evolution reactions are prepared by pulsed laser ablation with and without additional laser treatment (ALT). Transmission electron microscopy HR results show that copper is distributed along the dark titania surface both in the form of subnanometer oxide clusters and single atoms (SAs). After the ALT, the Cu dispersion increases, and a large number of SAs appear. The X-ray photoelectron spectroscopy data indicate that the increasing copper content as well as the ALT lead to an increase in the surface Ti 3+ content. Copper on the surface exists in the Cu + state, which is associated with the strong metal−support interaction (SMSI) effect between the defective TiO 2 support and a SA/subnanometer cluster of copper. Photocatalytic activity of nanoscale Cu-modified dark TiO 2 is studied in the hydrogen evolution from aqueous glycerol solution under irradiation with light-emitting diodes (LEDs) 375 (soft ultraviolet) and LED 410 (visible region). In all cases, the modification of the surface with copper significantly increases the hydrogen yield in both the UV and visible regions. The ALT also leads to an increase in the photocatalytic activity of materials due to an increase in the SMSI between copper species and the surface of the dark TiO 2 . For the process of photocatalytic hydrogen evolution, a mechanism is proposed, and the products of glycerol photooxidation are identified.

The use of photons to directly or indirectly drive chemical reactions has revolutionized the field of nanomaterial synthesis resulting in appearance of new sustainable laser chemistry methods for manufacturing of micro‐ and nanostructures. The incident laser radiation triggers a complex interplay between the chemical and physical processes at the interface between the solid surface and the liquid or gas environment. In such a multi‐parameter system, the precise control over the resulting nanostructures is not possible without deep understanding of both environment‐affected chemical and physical processes. The present review intends to provide detailed systematization of these processes surveying both well‐established and emerging laser technologies for production of advanced nanostructures and nanomaterials. Both gases and liquids are considered as potential reacting environments affecting the fabrication process, while subtractive and additive manufacturing methods are analyzed. Finally, the prospects and emerging applications of such technologies are discussed.
