“…HR-STEM investigations indicated the presence of fully metallic Pt-NPs with mainly spherical and spherical-like shapes using different RR values. Finally, the fully metallic nature of the NPs and the smaller mean size, i.e., 2.2 nm ± 1.2 nm, obtained in our study differ from that reported in [ 2 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ].…”

“…Condorelli et al fabricated Pt-NPs in water and NPs already formed were ablated in polyynes by Nd:YAG with a fundamental wavelength. They obtained the small mean size value of 15 nm for the latter, while the mean size value for the Pt-NPs in water was between 15 and 20 nm [ 49 ]. Madlum et al prepared Pt-NPs in DDW using Nd:YAG (λ = 1064 nm) with a changing number of laser pulses.…”

Our work presents, for the first time, a comprehensive study of the synthesis of fully metallic platinum nanoparticles (Pt-NPs) involving the ablation process in double distilled water using a KrF excimer laser. To obtain detailed information on Pt-NP morphology and optical properties, prepared colloids were characterized using High Resolution Scanning Transmission Electron Microscopy (HR-STEM) with advanced capabilities for Energy Dispersive X-ray Analysis (EDX), UV/Vis optical spectroscopy, and Direct Analysis in Real Time—Mass Spectrometry (DART-MS). The influence of the applied laser fluence and laser repetition rate (RR) values on the characteristics of the obtained Pt-NPs and the ablation process, respectively, were also analyzed. Spherical and spherical-like nanoparticles exhibiting aggregation were produced. The Pt-NP mean size values were between 2.2 ± 1.2 nm and 4.0 ± 1.0 nm, while their interplanar distance measurements showed a face-centered cubic (FFC) Pt lattice (111), as revealed by HR–STEM measurements, for all investigated samples. The smallest mean size of 2.2 nm of the Pt-NPs was obtained using a 2.3 J cm−2 laser fluence at a 10 Hz RR, and the narrowest size distribution of the NPs was obtained with a 2.3 J cm−2 laser fluence at a 40 Hz RR. A linear dependence of the Pt-NP diameters versus the laser repetition rate was found at a constant fluence of 2.3 J cm−2. The proposed eco-friendly synthesis route of Pt-NPs, because of its relative simplicity, has the potential for use in industrial production.

“…The sp-carbon chains were synthesized by also employing metal targets, i.e., gold, [133,134] or exploiting the catalytic effect of metal nanoparticles. [135] Pan et al achieved the synthesis of "carbyne" with finite length made by 10 carbon atoms from ablation of a gold target in ethanol. [133] The authors suggested that both the gold target and ethanol played a fundamental role in the formation mechanism of carbyne by PLAL.…”

“…The catalytic role of metal targets is further investigated by Condorelli et al [135] Indeed, they managed to produce Pt nanoparticles encapsulated in sp-carbon chain shells by PLAL of a graphite target in a colloidal solution of Pt nanoparticles. [135] These compounds were investigated by Raman and x-ray photoelectron (XPS) spectroscopy. The growth of sp-carbon chains around Pt nanoparticles prevents the oxidation of the latter, while the formation of Pt-C bonds stabilizes the sp-carbon chains.…”

This review provides a discussion of the current state of research on sp-carbon chains synthesized by pulsed laser ablation in liquid. In recent years, pulsed laser ablation in liquid (PLAL) has been widely employed for polyynes synthesis thanks to its flexibility with varying laser parameters, solvents, and targets. This allows the control of sp-carbon chains properties as yield, length, termination and stability. Although many reviews related to PLAL have been published, a comprehensive work reporting the current status and advances related to the synthesis of sp-carbon chains by PLAL is still missing. Here we first review the principle of PLAL and the mechanisms of formation of sp-carbon chains. Then we discuss the role of laser fluence (i.e. energy density), solvent, and target for sp-carbon chains synthesis. Lastly, we report the progress related to the prolonged stability of sp-carbon chains by PLAL encapsulated in polymeric matrices. This review will be a helpful guide for researchers interested in synthesizing sp-carbon chains by PLAL.
