Study of the optical and structural properties of Pt nanoparticles prepared by laser ablation as a function of the applied electric field

Nanoparticles Engineering by Pulsed Laser Ablation in Liquids: Concepts and Applications

“…Al-Haddad et al [ 137 ] synthesized Au NPs by pulsed laser (Nd:YAG, λ = 1064 nm), ablation of a gold target immersed in deionized water by 300 mJ of laser energy, while a DC electrical field was applied above the target with adjusted voltage. The influence of the applied electric field on the formation of platinum NPs by laser (Nd:YAG, λ = 1064 nm) ablation technique was investigated by Moniri et al [ 138 ]. Furthermore, laser ablation of germanium in liquids with static, externally applied electric fields is discussed in [ 139 ].…”

The effect of applied electric field on the micromorphology of Pt nanoparticles synthesized by laser ablation

“…The experiment was done at room temperature and the duration of ablation process was 15 min for all samples. Figure 1 represents the schematic set up of EFLAL (Moniri et al, 2017). As can be seen, the synthesis of Pt NPs is ascribed to the interaction between the electric field and laser beam so that because of the high pressure and temperature, the Pt plasma is formed initially.…”

“…Since the shape, structure, and size of metal NPs have strong influences on their catalytic properties and micromorphology, the electrical field‐assisted laser ablation in liquids (EFLAL) can be considered as a good candidate for fabricating NPs with controlled size and unique morphology. The width and wavelength of the laser, the applied electric field, and the types of liquid are some examples of parameters that affect the structural, physical, and optical properties along with micromorphology of samples (Moniri, Hantehzadeh, Ghoranneviss, & Asadabad, 2017).…”

The Water-Based Synthesis of Platinum Nanoparticles Using KrF Excimer Laser Ablation

“…Colloidal platinum nanoparticles (Pt-NPs) have attracted significant attention due to their physical and chemical properties, including stability, dispersion, size, shape, and morphology, which further determine their final applications, ranging from biotechnology to electronics. They may act as strong catalysts for the reduction of polluting gases generated by vehicles [ 1 ] or for the elimination of nitrous oxide generated in combustion processes [ 2 ], and they may enhance the catalytic activity for oxygen reduction reactions during the operation of proton exchange membrane fuel cells [ 1 , 3 ]. They have important applications in oxygen reduction reactions (ORRs) due to their remarkable electrocatalytic characteristics [ 4 ].…”

“…The extremely wide range of Pt-NP applications also includes coatings [ 10 ], textiles [ 11 ], nanofibers [ 12 ], plastics [ 13 ], magnetic nanopowders [ 14 ], multifunctional membranes [ 15 ], and cancer therapy [ 16 , 17 ]. Moreover, Pt-NPs are largely used in electronics manufacturing for the fabrication of internal electrodes of multilayer ceramic capacitors [ 1 , 18 ] or as conductor paste in conductive thick-film-integrated circuits [ 19 ]. Because of the wide range of applications in the nanotechnology of Pt material, further investigations can increase control over their properties.…”
