Mechanosynthesis of ultra-small monodisperse amine-stabilized gold nanoparticles with controllable size

Abstract

We report a fast mechanochemical method for making gram amounts of monodisperse and ultra-small gold nanoparticles in the size range of ∼1-4 nm, without external reducing agents or bulk solvents.

Advances in Solid-State Transformations of Coordination Bonds: From the Ball Mill to the Aging Chamber

“…Although the ability to induce transformations of solids by grinding or milling has been known for millennia [ 55 ], only recently has it been validated as a versatile method to conduct organic [ 56 , 57 ], inorganic [ 58 ], and organometallic [ 59 , 60 ] transformations leading to diverse high-value materials, including pharmaceuticals [ 61 , 62 ], nanoparticles [ 63 , 64 ], hybrid [ 65 ] and microporous materials [ 66 , 67 , 68 ]. Solid-state chemistry appears particularly amenable to the self-assembly of complex structures, through hydrogen bonding, reversible covalent chemistry or formation of coordination bonds, with a large array of literature examples demonstrating the synthesis of small molecule complexes [ 1 , 69 ], (supra)molecular or metal-organic clusters and cages [ 70 , 71 , 72 ], as well as coordination polymers [ 73 , 74 , 75 ].…”

Metal-catalyzed organic reactions using mechanochemistry

“…This innovative strategy, of using the vial and ball material as a catalyst in a mechanochemical reaction, has been subsequently used in a number of other mechanochemical reactions (vide infra) and nanoparticle syntheses. 49 An efficient, entirely copper-free mechanochemical Sonogashira coupling was reported in 2010 by Thorwirth et Table 3), 50 who utilized Pd(OAc) 2 in the presence …”

Comparison of Chemical and Biological Properties of Metal Nanoparticles (Au, Ag), with Metal Oxide Nanoparticles (ZnO-NPs) and their Applications

“…For instance, increasing the reaction times caused to a growth in the size of the AuNPs stabilised by octadecyl-amine ligand. Consequently, the size of the NPs can also be controlled via changing time of the reaction, while kept high monodispersity [50]. According to Noorizadeh et al [51] reported that, amino ligands such as (3aminopropyl)-triethoxysilane were used to functionalize iron oxide NP/SiO2-NH2 for selective removal of arsenic (which is an extremely toxic metalloid for human, plants and animals) in water is evaluated.…”
