“…In our case however, the catalyst is dissolved in a solution. Since the printed iron catalyst consists of a gel-like material that forms a Fe 2 O 3 film after annealing [12] and no step is taken to reduce the catalyst, we conclude that in our case the catalyst is not pure metal, but metal oxide. This may significantly change the behavior of the catalyst.…”

“…The solutions were Fe( A period of 12 h for this "aging" of the solution was found to be ideal for the catalytic growth of nanotubes [12]. The printing was performed by placing the stamp on the surface of the SiO 2 /Si wafer for 3 s.…”

“…For example, they are capable to work as efficient field emitters [7] and can form a basis for very robust fibers [8]. Nanotubes can be produced by arc discharge [2], by laserablation [9] or by chemical vapor deposition techniques (CVD) [10,11,12,13,14,15,16]. CVD is currently the most promising and flexible method with regard to applications, but our understanding of the influence of the catalyst and the deposition parameters on the nanotube growth is still fragmentary.…”

“…Microcontact printing (µCP) has become an often applied method in the last few years because it is a simple way to define chemical patterns on a variety of substrates [17,18,19]. We use this method to selectively deliver a catalyst to the substrate surface, which in turn activates the growth of nanotubes [12]. The advantage of the patterning is that one can compare the regions with and without catalyst, and thus exactly determine the role of the catalyst.…”

Three different catalysts (Fe, Ni, Co nitrates dissolved in ethanol) were patterned on a SiO2/Si substrate and multi-wall carbon nanotubes were grown by catalytic decomposition of acetylene. We compare the growth of the carbon nanostructures in the temperature range between 580• C and 1000• C. With our experimental set-up the catalyst solutions of cobalt and nickel were found to be less efficient than the one of iron. An optimal production of multi-wall nanotubes was observed at temperatures between 650• C and 720• C with the iron solution as catalyst. We found a tendency towards thicker structures with higher temperatures. Finally, we suggest a mechanism for the growth of these carbon structures.
