“…Despite these very attractive features, studies on the synthesis of trimetallic noble metal nanomaterials are still limited, and the role of the third metal over the performances, relative to their bimetallic systems, remains unclear. This is probably due to the lack of experimental procedures to the synthesis of trimetallic nanostructures with well-defined shapes and controllable compositions, which hinders the systematic correlation between shape, composition, and performance [11,22,27,[29][30][31].…”

“…Trimetallic nanoparticles have shown improved catalytic performances relative to their mono-and bimetallic counterparts for a variety of reactions that include cyclohexene and glucose oxidation, the electrooxidation of formic acid, and C-C coupling [23][24][25][26]. It has been proposed that trimetallic systems may present distinct properties relative to their mono-and bimetallic counterparts, which enables, at least in principle, the design of nanomaterials with optimized performances [11,21,22,27,28]. Despite these very attractive features, studies on the synthesis of trimetallic noble metal nanomaterials are still limited, and the role of the third metal over the performances, relative to their bimetallic systems, remains unclear.…”

The synthesis of trimetallic nanoparticles represents an emerging strategy to maximize catalytic performances in noble metal-based catalysts. However, the controllable synthesis of trimetallic nanomaterials as well as the exact role played by the addition of a third metal in their composition over catalytic performances remains unclear. In this paper, we describe the synthesis of trimetallic nanoshells having AgAuPd, AgAuPt, and AgPdPt compositions by a sequential galvanic replacement reaction approach between Ag nanospheres as sacrificial templates and the corresponding metal precursors, i.e., AuCl 4 -(aq) , PdCl 4 2-(aq) , and/or PtCl 6 2-(aq) . In each of these systems, the composition could be systematically tuned by varying the molar ratios between Ag and each metal precursor. Nanoshells having Ag 56 Au 28 Pd 16 , Ag 78 Au 9 Pt 13 , and Ag 71 Pd 16 Pt 13 compositions were employed as model systems to investigate the effect of the addition of the third metal in their composition over the catalytic activities toward the 4-nitrophenol reduction. Our data demonstrate a significant enhancement in conversion percentages and thus the catalytic activities relative to the sum of their bimetallic counterparts, and this increase was dependent on the nature of the metals, corresponding to 826, 135, and 56 % for Ag 56 Au 28 Pd 16 , Ag 78 Au 9 Pt 13 , and Ag 71 Pd 16 Pt 13 nanoshells relative to their bimetallic analogs. The results presented herein demonstrate the strong correlation between catalytic activity and composition in multimetallic nanoshells, and that the incorporation of a third metal may represent a promising approach to boost catalytic activities for a variety of transformations.

A porous trimetallic Au@Pd@Ru nanoparticle system: synthesis, characterisation and efficient dye degradation and removal

A facile room temperature one-pot synthesis of trimetallic porous Au@Pd@Ru nanoparticles (Au@Pd@RuNPs) has been developed. The trimetallic nanoparticles have been prepared by the successive sacrificial oxidation of cobalt nanoparticles (CoNPs). The average particle size of Au@Pd@RuNPs is 110 nm. The porous nature and the presence of Au, Pd and Ru have been confirmed via TEM, FE-SEM and EDS analyses. The trimetallic nanoparticles have shown excellent catalytic activity towards the reduction of p-nitrophenol and efficient degradation of various azo dyes. This has been further extended towards the removal of colour from waste water via the catalytic degradation of azo dyes. Moreover, the produced amine can be eliminated from the waste water via its sorption on an industrial solid waste dolochar.

Nanoalloys (NAs), which are distinctly different from bulk alloys or single metals, take on intrinsic features including tunable components and ratios, variable constructions, reconfigurable electronic structures, and optimizable performances, which endow NAs with fascinating prospects in the catalysis field. Here, the focus is on NA materials for chemical catalysis (except photocatalysis or electrocatalysis). In terms of composition, NA systems are divided into three groups, noble metal, base metal, and noble/base metal mixed NAs. Their design and fabrication for the optimization of catalytic performance are systematically summarized. Additionally, the correlations between the composition/structure and catalytic properties are also mentioned. Lastly, the challenges faced in current research are discussed, and further pathways toward their development are suggested.
