Morphology control of Cu(OH)2 nanowire bundles via a simple template-free route

Synthesis of Copper Hydroxide Branched Nanocages and Their Transformation to Copper Oxide

“…Synthetic strategies to form complex 3-dimensional or hollow structures of CuO have been studied by using Cu 2 O and copper hydroxide [Cu(OH) 2 ] as templates. ,, Copper hydroxide is the best candidate as a template as it is an intermediate product in the most common synthetic strategy, the hydrothermal method, to form CuO nanostructures. ,, One strategy to fully utilize the underlying structure of the Cu(OH) 2 intermediate is by isolating it from solution and dehydrating it in the solid state. − However, currently the shape control of CuO via both of these methods is limited to nanoparticles, one-dimensional nanostructures, , two-dimensional nanostructures, and three-dimensional urchin-like nanomaterials. , The reason for these limitations is that the shape-controlled syntheses of the Cu(OH) 2 template is equally as limited. , …”

“…9,22 The reason for these limitations is that the shape-controlled syntheses of the Cu(OH) 2 template is equally as limited. 23,24 Herein we describe a facile and scalable room temperature synthesis of complex branched Cu(OH) 2 nanocages and their conversion into CuO branched nanocages and Cu 2 O nanoframes. The use of Cu(OH) 2 as a template is shown to allow the synthetic control over the proportion and length of the branches, as well as the size of the nanocage core.…”

An ordered array based on vapor-processed phthalocyanine nanoribbons

“…In comparison, the nanowire/nanoribbon bundle is a generally observed morphology for a variety of organic and inorganic nanowires in both vapor and solution growth methods. [9][10][11][12][13][14][15][16][17][18] Obviously, the bundle-like nanoribbons are easily obtained with simpler growth condition control. If the nanoribbon arrays can be formed based on the bundle-like structure, a simple electrode fabrication process combined with the facile growth method makes the nanoscaled device fabrication dramatically accelerated.…”

“…On the other hand, the nanowire/ nanoribbon bundle is a generally observed morphology for a variety of organic and inorganic nanowires. [9][10][11][12][13][14][15][16][17][18] Based on the nanowire/nanoribbon bundles, a pushing transfer method has been used to obtain highly ordered nanoribbon arrays. Based on these nanoribbon arrays, one of the most difficult steps in the process of nanodevice fabrication, i.e., transferring the nanoribbon to the substrate, can be overcome, and the large-scale and high-efficiency fabrication of nanoscaled organic eld-effect transistors (OFETs) can be realized.…”
