The development of highly surface-active nano-sized and submicron particles with well-defined features is a promising approach in regulating various physicochemical properties of materials for different applications. A new hybrid technique involving pulsed laser irradiation and sonochemical processes for the production of Pd nanoparticles, NiPd alloys, and ZnO and Ag/graphene oxide (GO) composites was developed herein. An unfocused pulsed laser (neodymium-doped yttrium aluminum garnet [Nd:YAG] laser pulse with a wavelength of 532 nm) was used to irradiate a mixture of colloidal Ni solution obtained by ablation and PdCl₂, resulting in the formation of highly surface-active NiPd under continuous sonication at 40 kHz. The physicochemical properties of the synthesized materials were analyzed by X-ray diffraction (XRD), ultraviolet–visible (UV–vis) spectroscopy, field-emission scanning electron …
