“…Yamada et al [23] reported that Ni was an effective catalyst due to its higher activity in producing filamentous carbon compared to Fe and Co as the classic catalysts for carbon nanofiber (CNF) and carbon nanotube (CNT) synthesis. As a continuation of our previous work, the present study is trying to develop a low-cost Ni-doped bamboo carbon by its simultaneous impregnation with NiCl 2 and HNO 3 via microwave heating for effective removal of Pb(II) from water.…”

“…The basic idea behind using a water soluble support returns to Steigerwalt and Lukehart [17] who employed silicate or carbonate. Metal catalysts, such as Fe [18][19][20][21], Ni [22,23], Cu [24], Co [25,26] and their alloys [27], have been investigated widely. However, until now, the reported catalysts require the lengthy process of reduction and calcination for their preparation [11,13].…”

Large scale synthesis of carbon nanofibres (CNFs) on a sodium chloride support has been achieved. CNFs have been synthesized using metal oxalate (Ni, Co and Fe) as catalyst precursors at 680 C by chemical vapour deposition method. Upon pyrolysis, this catalyst precursors yield catalyst nanoparticles directly. The sodium chloride was used as a catalyst support, it was chosen because of its non-toxic and water soluble nature. Problems, such as the detrimental effect of CNFs, the detrimental effects on the environment and even cost, have been avoided by using a water soluble support. The structure of products was characterized by scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. The purity of the grown products and purified products were determined by the thermal analysis and X-ray diffraction method. Here we report the 7600, 7000 and 6500 wt% yield of CNFs synthesized over nickel, cobalt and iron oxalate. The long, curved and worm shaped CNFs were obtained on Ni, Co and Fe catalysts respectively. The lengthy process of calcination and reduction for the preparation of catalysts is avoided in this method. This synthesis route is simple and economical, hence, it can be used for CNF synthesis in industries.

“…They can be divided into platelet, herring-bone and tubular types (Inagaki and Kang 2014). Recent progress in the synthesis of nanofibrs are given in the subsequent reports (Davoodi et al 2013;Retterer et al 2008;Röthlisberger et al 2013;Longtin et al 2007;Tu et al 2003;Pan et al 2005;Hashempour et al 2014;Lee et al 2008;Tao et al 2006;Chai et al 2007;Yamada et al 2006;Lee et al 2001;Thakur et al 2010;Ghavaninia et al 2011).…”

Phenol adsorption on different nano-sized carbon materials: first comparative study

2015

Carbon nanofibres and multi-branched carbon nanotubes are synthesized by using a new, proposed in this study method. The acid-base, adsorption and geometric properties of nanomaterials are characterised. Next we present first comparative adsorption and calorimetric studies of phenol uptake from aqueous solutions on mentioned nano-sized carbon materials and on nanotubes having similar diameter. The comparison of carbon nanofibres, multi-branched carbon nanotubes, and multi walled carbon nanotubes shows that for non-porous carbon nanomaterials the concentration of basic surface functionalities determines the mechanism of phenol adsorption. In consequence, larger phenol adsorption is recorded for the most basic nanomaterials (nanofibres and multi walled nanotubes) and smaller for multi branched nanotubes having the smallest surface concentration of basic groups. Possible explanation of differences between enthalpy of phenol displacement on graphite and on studied carbon adsorbents is also given.
