“…Because of their unique electronic and mechanical properties, CNTs are being used in a growing number of commercial applications such as composite materials, [150] electronic devices, [151] and fuel cells. [152] For unmodified CNTs, surface hydrophobicity prohibits their dispersion in water, making them difficult to use in many applications. This behaviour of pristine CNTs is consistent with the relative insolubility of C 60 molecules.…”

Environmental context. The fate and bioavailability of engineered nanoparticles in natural aquatic systems are strongly influenced by their ability to remain dispersed in water. Consequently, understanding the colloidal properties of engineered nanoparticles through rigorous characterisation of physicochemical properties and measurements of particle stability will allow for a more accurate prediction of their environmental, health, and safety effects in aquatic systems.This review highlights some important techniques suitable for the assessment of the colloidal properties of engineered nanoparticles and discusses some recent findings obtained by using these techniques on two popular carbon-based nanoparticles, fullerene C 60 and multi-walled carbon nanotubes.Abstract. The colloidal properties of engineered nanoparticles directly affect their use in a wide variety of applications and also control their environmental fate and mobility. The colloidal stability of engineered nanoparticles depends on their physicochemical properties within the given aqueous medium and is ultimately reflected in the particles' aggregation and deposition behaviour. This review presents some of the key experimental methods that are currently used to probe colloidal properties and quantify engineered nanoparticle stability in water. Case studies from fullerene C 60 nanoparticles and multi-walled carbon nanotubes illustrate how the characterisation and measurement methods are used to understand and predict nanoparticle fate in aquatic systems. Consideration of the comparisons between these two classes of carbonbased nanoparticles provides useful insights into some major current knowledge gaps while also revealing clues about needed future developments. Key issues to be resolved relate to the nature of near-range surface forces and the origins of surface charge, particularly for the reportedly unmodified or 'pure' carbon-based nanoparticles.

In this study, we describe the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition at 500°C to 975°C, over Co 3 O 4 /MgO catalyst. The size of Co 3 O 4 nanoparticles is controlled by changing cobalt nitrate concentration in aqueous solution by impregnation method. The main object of this study is the synthesis of CNTs that started suddenly without any preheating of catalyst nanoparticles. The effect of sudden initiation and conventional preheating processes of catalyst nanoparticles on yield of CNTs was then described. The results suggest that this sudden initiation of synthesis process affects the carbon yield and morphology of CNTs.

“…MWCNTs have electronic properties similar to those of graphite and are thus semimetals. They are promising for multiple applications including strong composite materials, field emission displays, and adsorbents for gas separation or storage [40][41][42][43][44][45][46][47]. Similar to SWCNTs, a continuous low-cost production method producing MWCNTs that are easily purified is required for MWCNTs to be incorporated in emerging technologies.…”
