“…Another very important factor is the synthetic process that can favor the formation of one or the other phase kind dependent on synthesis conditions. I.e Tang et al [ 20 ] reported the formation of AgPt, AgPd, and CuPt alloy nanoparticles and AgCuPt core-shell structure with an Ag core and CuPt shell by a co-reduction method. Selective incorporation of Pt on the Ag/Au nanoparticles by successive reduction method was demonstrated by Thongthai et al [ 21 ].…”

Multimetallic plasmonic systems usually have distinct advantages over monometallic nanoparticles due to the peculiarity of the electronic structure appearing in advanced functionality systems, which is of great importance in a variety of applications including catalysis and sensing. Despite several reported techniques, the controllable synthesis of multimetallic plasmonic nanoparticles in soft conditions is still a challenge. Here, mono-, bi- and tri-metallic nanoparticles were successfully obtained as a result of a single step laser-induced deposition approach from monometallic commercially available precursors. The process of nanoparticles formation is starting with photodecomposition of the metal precursor resulting in nucleation and the following growth of the metal phase. The deposited nanoparticles were studied comprehensively with various experimental techniques such as SEM, TEM, EDX, XPS, and UV-VIS absorption spectroscopy. The size of monometallic nanoparticles is strongly dependent on the type of metal: 140–200 nm for Au, 40–60 nm for Ag, 2–3 nm for Pt. Bi- and trimetallic nanoparticles were core-shell structures representing monometallic crystallites surrounded by an alloy of respective metals. The formation of an alloy phase took place between monometallic nanocrystallites of different metals in course of their growth and agglomeration stage.

“…The co-reduction method is a straightforward process since the reduction of three metal salts is carried out simultaneously. 99 Shi et al 100 fabricated Pt 53 Ru 39 Ni 8 trimetallic nanosponges using the co-reduction wet chemical method, using hydrogen bubbles from the hydrolysis of sodium borohydride as a dynamic template for the synthesis of the spongelike structure. The trimetallic nanosponges were prepared without support on a clean surface or additional organic solvent or seed (Fig.…”

“…The chemical composition of the alloy was chosen under the assumption that this alloy had a high catalytic potential [13][14][15][16], as well as a high configurational entropy of mixing (∆S mik conf = 1.61 R) [17]. Previous research in the field of synthesis of multi-component noble nanoparticles represents the successful synthesis of bimetallic [18,19] and trimetallic nanoparticles from the initial aqueous solution. AgPd and AgPt are used to improve catalysis in H 2 O 2 generation, while Cu-based particles such as CuPt and AgCuPt have been observed to exhibit high catalytic activity in the electrochemical reduction in CO 2 [19].…”

The development of new multicomponent nanoparticles is gaining increasing importance due to their specific functional properties, i.e., synthesised new complex concentrated nanoparticles (CCNPs) in the form of powder using ultrasonic spray pyrolysis (USP) and lyophilisation from the initial cast Ag20Pd20Pt20Cu20Ni20 alloy, which was in the function of the material after its catalytic abilities had been exhausted. Hydrometallurgical treatment was used to dissolve the cast alloy, from which the USP precursor was prepared. As a consequence of the incomplete dissolution of the cast alloy and the formation of Pt and Ni complexes, it was found that the complete recycling of the alloy is not possible. A microstructural examination of the synthesised CCNPs showed that round and mostly spherical (not 100%) nanoparticles were formed, with an average diameter of 200 nm. Research has shown that CCNPs belong to the group with medium entropy characteristics. A mechanism for the formation of CCNPs is proposed, based on the thermochemical analysis of element reduction with the help of H2 and based on the mixing enthalpy of binary systems.
