“…EtOH is known to decompose by either the dehydration reaction seen in Equation (5) or by cleavage of the C-C bond connecting the methyl group and the methylene group as seen in Equation (6) [51,52]. The dehydration reaction (Equation (5)) dominates under the conditions that are employed here [52].…”

Abstract:The growth of carbon nanotubes (CNTs) by direct liquid injection chemical vapor deposition (DLICVD) In order to screen different growth conditions a single large batch of FeMoC is required in order to eliminate variation in the catalyst precursor. The preparation of 6 g of FeMoC is possible by scaling (10×) literature reagent ratios. DLICVD studies of the FeMoC derived carbon product were evaluated by Raman spectroscopy and scanning electron microscopy (SEM) to determine the quality (G:D ratio) and purity of CNT content. With the use of ethanol as the carbon source, increasing the temperature in the injection zone (aspiration temperature) above 250 • C increases the yield, and results in a slight increase in the G:D ratio. The maximum yield is obtained with a growth temperature of 900 • C, while the G:D ratio is the highest at higher temperatures. Faster solution injection rates increase yield, but with a significant decrease in G:D, in fact no CNTs are observed in the product for the highest injection rate (10 mL/h). An optimum catalyst concentration of 1.25 wt.% is found, which influences both the catalyst:C and catalyst:H ratios within the system. Growth at 800 • C is far more efficient for toluene as a carbon source than ethanol. The resulting "process map" allows for large quantities of CNTs to be prepared by DLICVD.

“…Although carbon nanotubes (CNTs) are of interest for numerous applications, such as high-performance composites, electronics, and energy storage devices [1][2][3][4][5][6], and the current production lacks structural control, resulting in a range of chiralities and diameters. To realize their potential controlled growth of CNTs is desired.…”

“…Another challenge for these materials is that their increased surface areas and surface defects make them more susceptible to side reactions and uncontrolled growth of the solid electrolyte interphase layer (SEI). In Li-ion batteries, this growth is the main contributor to lithium-ion inventory loss and raise in interphasial resistance of anodes which limits the life cycle of the cells [1,4,8,9]. And strategies to avoid these problems are not usually readily available or easy to implement.…”

“…For this proof of concept study we chose Fe because it is the most common growth catalyst used; metallic Fe itself is not electrochemically active towards lithium but the electrochemical behavior of its oxides and hydroxides is very well known and documented. Other possible growth catalysts could include traditional ones such as Ni, Co, Cu, manganese oxides, and some more recently reported such as MgAl oxides and oxyhydroxides, or TiO 2 [4,5,10,12].…”

“…Despite great promise, nanocarbonaceous electrodes have not yet met with the expected commercial success due, in part, to increased complexity and cost during electrode processing. Filamentous nanocarbons-whether graphitic or amorphous-are usually prepared by high energy methods such as chemical vapor deposition (CVD) pyrolysis, arc-discharge, etc., after which they are removed from the growth substrate and treated with acidic solutions before a slurry can be prepared [1,[4][5][6]. Nanoparticulate matter, however, is much more difficult to disperse in slurry than other commercial battery materials; this is specially challenging for filamentous nanocarbons [1,3,7,8].…”

The processing of battery materials into functional electrodes traditionally requires the preparation of slurries using binders, organic solvents, and additives, all of which present economic and environmental challenges. These are amplified in the production of nanostructured carbon electrodes which are often more difficult to disperse in slurries and require more energy-intensive and longer processing. In this study we demonstrate a new process for preparing binder-free nanocarbon/nanoparticle (Fe-C) composite electrodes and study the effect of processing on the nanocomposite's cycling performance in lithium cells. The binder-free electrodes were prepared by a two-step method: pulsed-electrodeposition of iron-based catalyst followed by chemical vapor deposition of a carbon film. SEM and TEM of the Fe-C showed that the active materials have a fibrous and tortuous morphology with disordered nanocrystalline domains characteristic of an amorphous carbon. The Fe-C electrodes showed good mechanical stability and an excellent cycle performance with an average stable capacity of 221 mAhg -1 , and 85% capacity retention for up to 50 cycles. By reducing the number of processing steps and eliminating the use of binders and other chemicals this new method offers a ''greener'' alternative than current processing methods. Graphical abstractSynopsis: gains in sustainability can be achieved by eliminating use of binders, chemicals, and the number of electrode's processing steps in this new method.
