“…The mechanism of reduction of copper salts with ascorbic acid was well established and discussed in the literature . An efficient loading of copper nanoparticles and retain its high surface area, there is need to immobilize in a confined template that can be utilized for various applications of the Cu nanoparticles (CuNPs) . Many number of solid supports are reported in the literature to produce nanocomposites.…”

A biosynthesis of Copper Nanoparticles supported on Zeolite Y and its application as efficient, reusable, heterogeneous catalyst in C−N cross coupling reactions between amines and aryl halides are reported. The biosynthesis of CuNPs/Zeolite Y was achieved by the reduction of CuSO4.5H2O with the lemon juice (without peal) and encapsulated into the Zeolite Y in a single step. In this biosynthetic method, the ascorbic acid present in the lemon juice acted as a reducing agent for CuSO4.5H2O. The CuNPs/Zeolite Y was characterized using UV‐Vis, powder XRD, FT‐IR, HR SEM, EDS and TGA. The average size of the CuNPs are found to be 50 nm and has large surface area for the efficient catalysis. The new catalyst is effect in catalyzing the C−N cross coupling reaction between amines and aryl halides (yield ranging from 89% to 95% depends on amine and aryl halide used). The catalyst can be recovered from the reaction mixture by simple procedure. The recovered catalyst is found to be active in catalyzing the coupling reaction even after five runs.

“…In the case of embedded metals, the conversion step typically involves the reduction of metal cations. Reduction is routinely performed under harsh conditions, such as at high temperatures or with strong reducing agents, with some methods even utilising high‐energy radiation or plasma . However, MOFs tend to exhibit poor thermal and/or chemical stability, which severely limits the range of metals that can be embedded in MOF pores.…”

Interrogation of the Effect of Polymorphism of a Metal‐Organic Framework Host on the Structure of Embedded Pd Guest Nanoparticles

Metal‐organic frameworks (MOFs) are very promising host materials for nanoscale guest materials. However, some MOFs such as MIL‐53 are known to undergo phase transitions which can complicate the guest particle size control. In this study, Pd nanoparticles embedded in Al‐MIL‐53 were synthesised via (a) electrodeposition and (b) gas‐phase reduction. A thorough structural investigation revealed that each synthesis method most likely favoured a different phase of Al‐MIL‐53, presenting the possibility of MOF phase selection as a technique for size control of embedded nanoparticles. For the first time, we hereby report the use of pair distribution function analysis to successfully investigate the structure and morphology of guest particles embedded in a MOF host.
