“…In this regard, several efficient catalyst systems have been reported involving Ru, Co and Rh NPs [10], Au NPs [11], Cu (airstable), Ag, and Au NPs [4,12] monometallic Au, Ag, Cu, Pd, Ir and bimetallic CuAg and CuAu alloy NPs [13]. Additionally, many transition metal catalysts involving Rh [14e16], Ru [17,18], bimetallic NiPd [19], Ag [20], borane-based catalyst (CoeB, NieB and CueB) [21] have been tested for solutionphase dehydrogenation of amine borane but there is no report concerning the use of dimethylamine-borane by solvent-free approach.…”

The development of new synthetic strategies to obtain monodisperse metal nanoparticles on large scales is an attractive prospect in the context of sustainability. Recently, amine-boranes, the classical Lewis acid-base adducts, have been employed as reducing agents for the synthesis of metal nanoparticles. They offer several advantages over the traditional reducing agents like the borohydrides; for example, a much better control of the rate of reduction and, hence, the particle size distribution of metal nanoparticles; diversity in their reducing abilities by varying the substituents on the nitrogen atom; and solubility in various protic and aprotic solvents. Amine-boranes have not only been used successfully as reducing agents in solution but also in solventless conditions, in which along with the reduction of the metal precursor, they undergo in situ transformation to afford the stabilizing agent for the generated metal nanoparticles, thereby bringing about atom economy as well. The use of amine boranes for the synthesis of metal nanoparticles has experienced an explosive growth in a very short period of time. In this Minireview, recent progress on the use of amine boranes for the synthesis of metal nanoparticles, with a focus towards the development of pathways for sustainability, is discussed.

“…It is apparently noticeable from the spectra that there is a shift to lower wavenumbers of the carbonyl group of pure PVP from 1662 to 1643 cm -1 when metal NPs are embedded in it. This implies that there is an interaction between polymer and the gold metal NPs, which is due to the chemisorption of PVP molecules on the surface of the gold atoms [49,50], thereby stabilizing it [51]. A weak coordinative bond between oxygen atoms in carbonyl group of PVP and metallic Au atoms is the likely cause for the interaction [52][53][54].…”

A simple and novel strategy was developed to fabricate hydrogen peroxide (H 2 O 2 ) sensor based on gold nanoparticles (NPs) stabilized in polyvinylpyrrolidone. The formation of polymer-stabilized gold NPs (PSGN) was confirmed by UV-Vis spectroscopy, X-ray diffraction analysis and high-resolution transmission electron microscopy. Fourier transform infrared spectroscopy is used to elucidate the interaction between the polymer and the gold NPs. The electrochemical activities of the PSGN-modified electrode were characterized by cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy. The electrochemical results show remarkable electrocatalytic activity of the PSGN-modified electrode towards H 2 O 2 detection. The modified electrode exhibits a wide linear range with low detection limit of 0.7 lM. The fabricated sensor shows good reproducibility, long-term stability and high selectivity towards other electroactive species as well. Thus the proposed sensor seems to be a potential candidate for developing a simple, rapid and cost-effective enzymeless biosensor.
