Electrochemical reduction of carbon dioxide (CO 2 ) is a viable solution for conversion of atmospheric CO 2 to value-added materials such as carbon monoxide (CO). In this project, a new urea iron-tetraphenylporphyrin-dimer (Fe-TPP-Dimer) was synthesized and applied for electrocatalytic CO 2 reduction under both homogeneous and heterogeneous conditions to selectively reduce CO 2 to CO. Immobilization of the catalyst onto carbon nanotubes (CNTs) in aqueous solution resulted in remarkable enhancement of its electrocatalytic abilities, with exceptional turnover frequencies (10 s À 1 ), high faradic efficiency (FE) of ∼ 90%, and a current density of 16 mA/cm 2 at À 0.88 V vs. RHE. This project exhibits the importance of molecular design in accessing heterogeneous applications with CNTs.Consumption of fossil fuels for energy production in recent decades has dispensed alarming amounts of carbon dioxide (CO 2 ), one of the leading contributors to climate change, into the atmosphere. [1][2][3][4][5] Although the capture and conversion of CO 2 to value-added synthons has become a desirable solution to this problem, challenges in regard to the species' general lack of reactivity and the costs associated with deployment and stability of such strategies remain prevalent. [6][7][8][9][10][11] In this respect, electrocatalytic CO 2 reduction reactions (CO 2 RRs) pose a promising alternative to this end. [12][13][14][15][16][17][18][19][20] Extensive research has been conducted on both homogeneous and heterogeneous molecular catalysts for CO 2 RR. [21][22][23][24] Although homogeneous catalysts are popular for CO 2 RR application, applying heterogeneous catalysts is essential for emerging of CO 2 to CO conversion in large scale. Additionally, most molecular catalysts favor non-aqueous solvents such as N,N-dimethylformamide (DMF) and acetonitrile, making them more costly to implement. [25][26][27] Immobilization of molecular catalysts onto electrode surfaces can occur via several methods which include covalent bonding, [28,29] non-covalent attachment, [30,31] and surface polymerization. , [32,33] Among them, non-covalent surface binding methods that capitalize on strong Van der Waals π-π interactions between carbon surfaces and polyaromatic hydrocarbon moieties is easily accomplished and displays great surface stability, [31,34] making it a favorable technique for immobilization. [30,[35][36][37][38] Carbon nanotubes (CNTs) are of particular interest for CO 2 electroreduction owing to their high stability, conductivity and large surface area. [19,31,[39][40][41][42] Among transition metal complexes, iron, [24,25,[43][44][45] cobalt [46][47][48] and nickel, [49][50][51] are prevailing and more environmentally friendly than other metals used for CO 2 RR application. Metalloporphyrin catalysts are attractive as molecular catalysts in this field because of their robust structure and their stability to harsh conditions such as high temperatures. [52] Demonstrative work by Savéant showed that iron tetraphenylporphyrin (Fe-TPP) complexe...

“…The CO 2 is easily formed by the oxidation of organic molecules during combustion or respiration. Furthermore, CO 2 can be acquired from natural reservoirs or recovered as a byproduct of industrial chemical processes, so, no new production of CO 2 is necessary and there will be no addition to greenhouse gases (Young et al, 2000). This work presents the successful production of CNTs and CNFs by catalytic decomposition of methane (CH 4 ) and CO 2 over an unsupported nickel alloy catalyst (LaNi 5 ) in a 'modified' SFCCVD reactor (Figure 8) at temperatures ranging from 650-850°C (Moothi, 2009;Maphutha, 2009 It was observed that CH 4 produced well defined CNTs at all the tested temperatures (650-850°C) as shown in Figure 9.…”

“…Since CO 2 is a gas at room conditions, its convenient removal from polymeric products is possible without costly drying and solvent removal processes. DuPont has recently announced plans for a major investment in the use of SCF_CO 2 for production of fluorinated polymers, see Young and DeSimone (2000). Single-phase solvents are very important in processes where phase separation, and its consequent capillary forces, is …”

DATES COVERED (From -To) ABSTRACTIn this paper, a selected list of emerging applications of supercritical fluids (SCFs) is presented. In particular, demonstrated facts for the promise of the nanoscale science and technology and its overlap or interface with the SCFs technology are presented. It is argued that nanoengineered materials at the nanoscale have mechanical, optical, chemical, and electrical properties quite different from the bulk material. Examples of enhanced performance of many such materials when they are used in practical applications are given. SCFs, in particular carbon dioxide, on account of their special properties such as zero surface tension, low viscosity, and high solubility, enable them to play a critical role in many advanced technology applications. For example, as miniaturization efforts approach the nanoscale, surface tension forces become an important factor in many nanotechnology processes such as lithography in the electronic industry. In particular, the zero-surface-tension property of the SCFs presents them as a natural choice for nanotechnology. This article maybe used for research, teaching and private study purposes.
