Ultrathin Nanowires—A Materials Chemistry Perspective

The recent years have seen an explosive interest in one‐dimensional nanostructures1, as testified by the number of citations this field has accrued; as customary, its blossoming was enabled by chemical breakthroughs that allowed the reproducible and affordable synthesis of such structures.2, 3 The limitations of those syntheses was in the diameter of the nanowires that it could produce (hardly < 10 nm), and in the use of expensive and low‐yield techniques, such as chemical vapor deposition (CVD). This paper attempts to summarize the very recent chemical breakthroughs that have allowed the production of ultrathin nanowires, often in solution, and often in gram‐scale quantities. By no means is this a comprehensive coverage of the field, which can in part be found in other excellent reviews1, 2, 4–6 but a selection of those contributions that we feel would most help put this emerging field in perspective. We will review the various synthetic strategies, their pros and cons, and we will give our best guesses as to the future directions of the field and what we can expect from it.

“…Similar results were obtained using MCM-41, SBA-15, and HMM-1 as supports. We have so far synthesized nanowires of Rh, Pd, Pt, Au and bimetallic Pt-Rh, Pt-Pd by the photoreduction method [14][15][16][17][18][19][20][21][22][23][24].…”

“…Therefore, the mesoporous silicas provide great opportunities as a template of nanostructured materials. 2 In our study of the ship-in-bottle synthesis of metal clusters in microporous zeolites [7,13], we extended this chemistry from zeolites to mesoporous silicas and found the formation of metal nanowires in the mesopores [14][15][16][17][18][19][20][21][22][23][24]. Here we report selective synthesis of metal nanowires and nanoparticles in FSM-16 and HMM-1.…”

Adsorption of hydrogen peroxide on functionalized mesoporous silica surfaces

MCM-41 and MSU-H mesoporous silicas were successfully functionalized with hydrogen bonds forming organic moieties, which have been proven by elemental analysis. Both moieties, based on oxygen and nitrogen containing groups, were introduced with high efficiencythe amount of carbon in all cases exceeded 10 % and the elemental ratios suggest binding to the surface through two or three Si-O-Si bonds. Hydrogen peroxide adsorption was conducted in its aqueous solutions and the amount adsorbed was determined using the ferric thiocyanate method. Results are presented as a function of hydrogen peroxide concentration in aqueous solution from 5 to 30 %. Both functionalized silicas show increased adsorption capacity when compared with that of their unfunctionalized analogues. The surface modified with nitrogen-based organic moiety revealed better adsorption properties as well as higher resistance against oxidation. MSU-H silica, due to its larger pore diameter, provides more space to bind hydrogen peroxide molecules and thus was found to have higher adsorption capacity: it adsorbed up to four times more hydrogen peroxide than MCM-41.
