Bimetallic Pt–Ni Two-Dimensional Interconnected Networks: Developing Self-Assembled Materials for Transparent Electronics

“…Additionally, the reducing agent volume during the synthesis of different Pt–Ni NPs was kept constant. However, based on previous experiments, it is known that the NaBH 4 -to-metal-salt ratio greatly impacts the gelation process, and a certain minimal borohydride concentration is necessary to obtain stable colloidal solutions. , Here, the nominal molar ratios of Pt 1.5 Ni, Pt 3 Ni, Pt 4.5 Ni, and Pt 6 Ni resulted in factual ratios of Pt 2 Ni, Pt 4.5 Ni, Pt 7.5 Ni, and Pt 9 Ni bimetallic NPs, respectively. The results from STEM-EDX obtained for the 2D Pt–Ni aerogels (stamping method) are consistent with these findings.…”

“…The morphology of the resulting 2D bimetallic gels consists of porous architectures with nanowires that still display their particulate building blocks, allowing us to define the obtained structures as gels and aerogels. Pt 1.5 Ni, however, has a slightly different morphology, consisting of irregularly shaped single particles, which could be due to the high ratio of reducing agents to metal ions . The average diameter of the wire-like nanostructures increases with the Ni content, namely, around 4.7, 4.9, 6.0, and 6.2 nm for Pt 6 Ni, Pt 4.5 Ni, Pt 3 Ni, and Pt 1.5 Ni, respectively.…”

“…Nonetheless, for the up-scaled Pt 1.5 Ni, the fractal dimension is lower compared to the other 2D aerogels made by this approach. This is probably connected to the high agglomeration rate due to the low ratio of reducing agent to metal ions . It is worth mentioning that increasing the number of stacked layers of 2D bimetallic aerogels in order to overcome deficiencies in the morphology and to improve the electrical conductivity hampers further fractal dimension evaluations due to the overlapping of several structures.…”
