“…Other researchers grew Ndoped CNT from different metal nanoparticle catalysts and found that CNTs grown from MoO 3 exhibited the highest pyridinic N content and gave the highest activity. 272 Tuci et al 273 prepared N-doped multiwalled carbon nanotubes (MWCNTs) via chemical vapor deposition (CVD) of ethane and NH 3 to yield a material exhibiting high ORR activity. The N-doped MWCNTs were then functionalized with specific N substituents that covered up the existing active sites on the MWCNTs.…”

A comprehensive review of recent advances in the field of oxygen reduction electrocatalysis utilizing nonprecious metal (NPM) catalysts is presented. Progress in the synthesis and characterization of pyrolyzed catalysts, based primarily on the transition metals Fe and Co with sources of N and C, is summarized. Several synthetic strategies to improve the catalytic activity for the oxygen reduction reaction (ORR) are highlighted. Recent work to explain the active-site structures and the ORR mechanism on pyrolyzed NPM catalysts is discussed. Additionally, the recent application of Cu-based catalysts for the ORR is reviewed. Suggestions and direction for future research to develop and understand NPM catalysts with enhanced ORR activity are provided.

“…Pyrolyzed FePc-coated activated carbon (AC) was prepared by Liu et al By using evaporation-induced method self-assembly, the Fe-N-AC catalyst exhibits enhanced oxygen redox catalytic activity, owing the high content of nitrogen and iron in its composition, beyond high surface area, porosity, and crystalline structure [62]. Since then, other investigations have been demonstrating that nitrogen and iron content and species are highly influent on the base of catalytic activity of Fe-N 4 on the modified carbon materials as ORR catalysts [63,64]. Zhang and co-authors have shown a highperformance 3D hierarchical Fe-N-C catalyst composed via a combination of structured porous carbon framework with unsubstituted Pc/FePc complexes.…”

In this work, we initially report a detailed advancement in the utilization of metal-N 4 chelate macrocycles in the oxygen reduction reaction (ORR). Then, iron(II) phthalocyanines supported on two different carbon-based supports specifically carbon nanotube and black pearl (carbon spheres) were synthesized and their activities toward ORR in alkaline media were studied. With the help of physical and surface characterization like Raman, BET, XRD, XPS, and electron microscopy analysis, the similarity in surface chemistry and surface area of the materials and the differences in the structure and morphology of the supports were established. This work also brings forth the effect of support properties on the electrocatalytic activity of the materials by a detailed electrochemical analysis using rotating disk electrode in oxygen saturated 0.1 M KOH. Comparison with existing literature on Fe-phthalocyanine supported on diverse carbon support is presented.

Since their first allusion, carbon nanotubes have attracted significant research interest, especially with respect to composite manufacturing as a filler material for enhancing their mechanical and electrical properties. Several methods have been developed for modifying the electrical properties of carbon nanotubes such as CNTs wall's carbon atoms substitution with other appropriate atoms including engineering of their outer surfaces by covalent and noncovalent molecules, such as CNTs channel filling and nano-chemical reactions therein. CNTs with tailored electrical conduction open large perspectives for their applicabilities in advanced technologies. Taking into consideration the innovative advantages of pure and hybrid CNTs, in this article we have comprehensively reviewed the latest state-of-art research developments in the direction of different synthesis strategies, structure-property relationships, and advanced applications towards energy storage, supercapacitors, electrodes, catalytic supports, as well as biosensing.
