aPrior nanocluster size control typically involves some kind of template to physically limit the growth of the clusters to a particular size. These templates include inverse micelles, resins, gels, and cages.(7c-7g)For example, Pileni has prepared nanoclusters of Au(7b)and Cu(7c)in reverse micelles, using H2O concentration to control the size of the clusters (larger clusters were obtained at higher H2O concentration). Microgels(7d)and resins(7e, 7f)have also been used as templates with success, resulting in size-controlled supported nanoclusters. Using a sol−gel method to prepare TiO2nanoclusters, it was found that lowering the pH of the reaction system led to smaller clusters.(7g)The use of dendrimers is also common,(7h)larger nanoclusters being formed in larger, later-generation dendrimers. Pd clusters formed in an apo-ferritin cage to control their size were found to be active in the hydrogenation of alkenes(7i).

Although nanocluster size control using seed clusters is well established, this method presumes the availability of small seeds of controlled size, narrow size dispersion, and known composition, something that is more rare. Buhro and co-workers have cleverly used Au∼101(PPh3)21Cl5as seeds for Bi, In, and Sn nanoclusters with excellent results in size-dispersion control.(8b)Sau et al. used small gold nanoclusters as seeds for larger Au clusters;(8c)the sizes of the UV irradiation prepared seeds were controlled by the amount of reductant and nanocluster stabilizing ligand. Murphy et al. has examined the effects of rate of monomer addition to seeds on the growth of Au clusters on those seeds.(8d)Other examples of the seed method are available in the literature (e.g., see the refs summarized in the following references).

aInterestingly, size vs time curves similar to Figure 2 have been observed in the flocculation of activated sludge. In that case, population balance modeling of sludge particles, using mathematical formulas to describe floc formation via aggregation and destruction by breaking, was used to describe the flocculation process.(32b)

The approximations and definitions used to obtain eq14, and hence the equations which follow it, are: (i) that the two-step mechanism operates and closely fits the data (i.e., so that no agglomeration steps are present as is the case in the four-step mechanism for transition-metal nucleation, growthand two types of agglomeration, SchemeS1of theSupporting Information); (ii) that nucleation and growth are effectively separated in time, so that the number of nuclei remains constant after the end of the induction period; (iii) that the nanoclusters are monodisperse in size (this is in part a restatement of (ii)); (iv) that the bulk-metal density, ρ, is a reasonable approximation to the actual density of the nanocluster; and (v) thatN* (vide infra)is the number of atoms in the catalytically effective nucleus as defined and used herein. The approximations underlying the two-step treatment of the kinetic data, and extraction of two (average)k1andk2rate constants, are also built into the present treatment and as summarized in theSupporting Informationsection on “Simplifications and assumptions underling the Finke−Watzky mechanism for transition-metal nanocluster nucleation and growth”.

aIn this regard, the statement in the literature50bthat the F-W mechanism “is unable to provide any information about the sizedistribution(italics added) of nanoclusters” is correct at present, since average k1and k2values are obtained from the two-step kinetic model.

Buhro and co-workers have cleverly used Au\u223c101(PPh3)21Cl5as seeds for Bi, In, and Sn nanoclusters with excellent results in size-dispersion control.(8b)Sau et al. used small gold nanoclusters as seeds for larger Au clusters;(8c)the sizes of the UV irradiation prepared seeds were controlled by the amount of reductant and nanocluster stabilizing ligand. Murphy et al. has examined the effects of rate of monomer addition to seeds on the growth of Au clusters on those seeds.(8d)Other examples of the seed method are available in the literature (e.g., see the refs summarized in the following references)."
