“…The method was mainly focused on the preparation of Re NPs for metallurgical applications, claiming that a wide range of Re NPs (4-100 nm) can be obtained modifying the proportions of the different chemicals involved in the synthesis. Yurkov et al [25] produced Re NPs by thermal decomposition of Re 2 (CO) 10 , Re 4 O 6 (OCH 3 ) 12 and NH 4 ReO 4 in matrix of low-density polyethylene, thus obtaining a metal-containing composite. Chong and Fan [26] showed that Re 2 O 7 methanol solution placed within two silicon wafers can be reduced at 250 • C producing well dispersed ReO 3 nanocubes.…”

“…Though there are many potential applications for Re NPs as mentioned above, the preparation of Re NPs is not much studied in the literature. − One of the major problems of preparing zerovalent Re NPs is its readiness for simultaneous oxidation in aqueous colloidal solution. Hence, so far, wet chemical synthesis of stable Re NPs has been a really challenging and hard task.…”

Ultrafast formation of stable and self-assembled rhenium (Re) nanoparticles (NPs) using a poly allylamine hydrochloride (PAH) scaffold within 120 s of wet-chemical reaction at room temperature in aqueous solution has been reported. The average diameters of the two different sets of Re NPs synthesized are ∼0.7 ± 0.25 and ∼1.7 ± 0.3 nm, which can be easily achieved by controlling the polymer to Re7+ molar ratio. The small-size Re NPs are formed in solution, self-assembled together to form the chain-like or necklace-like structure. The synthesized Re NPs were used in two different potential applications, such as in catalysis and in surface-enhanced Raman scattering (SERS) studies. Catalysis study was done for 4-nitroaniline (4-NA) reduction with excess NaBH4 taking two different sets of Re NPs as catalyst. The highest catalytic rate for nitroaromatics reduction ever reported of ∼1.52 × 10–1 min–1 has been observed with large-size Re NPs as catalyst. In SERS, methylene blue (MB) was used as a Raman probe molecule. Strong SERS enhancements were observed with both sets of Re NPs due to their ultrasmall size, narrow interparticle gap, and self-assembled structure in PAH scaffold. These closely tethered and self-assembled Re NPs generated more surface active “hot spots” that resulted in good SERS enhancement. The present synthesis route is easy, cost effective, and fast and can generate stable Re NPs which could further be applied in interdisciplinary fields other than catalysis and SERS in the near future.

“…The same research group later synthesized ultra-small ReNPs in an organosol, where the mixture of NH 4 ReO 4 and DNA was first transferred from the aqueous phase to the organic phase using tetraoctylammonium bromide (TOAB) as a phase transfer catalyst under freezing conditions and then reduced by NaBH 4 [175]. Yurkov et al [41] employed a thermal decomposition approach to synthesize Re-polyethylene (Re@PE) nanocomposites. First, a mixture of PE and oil was heated under Ar flow.…”

“…In addition, it is a vital component of superalloys employed in space and aviation industries. Due to their exceptional mechanical properties as well as outstanding resistant to corrosion and oxidation even at elevated temperature, rhenium nanoparticles (ReNPs) are popular in electronics and catalytic applications [39][40][41].…”

Over the past decade, metal nanoparticles (MNPs) have attracted extensive attention due to their unique physiochemical properties that make them highly applicable in various fields such as chemical sensing, energy storage, catalysis, medicine, and environmental engineering. Their physiochemical properties depend drastically on the MNP size and morphology, which are largely determined by their synthesis methods. Research on MNPs predominantly focused on coinage metals (Au, Ag and Cu), but in the last decade research on metals with a relatively high melting temperature such as Pd, Co, and Re has seen rapid increases, mainly driven by their potential applications as catalysts. This paper presents the recent advances on different synthesis techniques of Co, Pd, and Re nanoparticles, their resulting nanostructures, as well as existing and potential applications.
