“…The CDC material doped using iron and 1,10-phenanthroline had a much more positive E onset of À32 mV and a E 1/2 of À164 mV, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 which shows the advantage of the porous CDC material. [29] This sample also had the largest oxygen content as determined by XPS. Using the step-wise synthesis procedure with the same amount of MWCNT and CDC yields a catalyst with ORR activity quite similar to that of FeÀNÀCDC-1, which is surprising, given that the activity of the Fe,N-co-doped MWCNTs was much lower than that of the catalyst synthesized using CDC.…”

“…This mixture is then pyrolyzed and the substrate along with inactive metal phases is removed by etching in acid mixtures, which allows for control over the porosity and structure by choosing the right substrate and reagents. [29][30][31][32][33] The main advantage of CDCs over other widely-used carbon supports is the amorphous nature and extremely high specific surface area that can be achieved (typically over 2000 m 2 g À1 ) [34] with highly reproducible largescale results already shown. [17] The resulting powder is then pyrolyzed to carbonize the MOF and dope it with transition metals and nitrogen, with the MOF playing a large role in directing the porosity and structure of the resulting catalyst.…”

Replacing Pt-based catalysts with noble-metal free catalysts for the oxygen reduction reaction (ORR) is one of the most important topics currently in electrocatalysis. Iron-and nitrogen-doped carbon materials have shown great promise in this area. In this work, we demonstrate the remarkable electrocatalytic activity towards the ORR of carbide-derived carbon (CDC) and multi-walled carbon nanotube (MWCNT) composite catalysts. The CDC material is synthesized from titanium carbide and doped using 1,10-phenanthroline and iron (II) acetate. The material is then mixed with MWCNTs and further modified with dicyandiamide (DCDA) and additional iron by using a multi-step pyrolysis procedure. The morphology, structure, porosity, and elemental composition are then comprehensively studied with scanning electron microscopy, X-ray photoelectron spectroscopy, N 2 physisorption, and inductively coupled plasma mass spectroscopy. The electrocatalytic activity of the catalysts for the ORR is studied using the rotating disk electrode method and in a single-cell anion exchange membrane fuel cell using the Tokuyama A201 membrane.

Proton/anion‐exchange membrane fuel cells (PEMFC and AEMFC), generating electricity from the H2 energy with zero‐carbon emission, have become very promising energy conversion devices to meet the increasing energy demand and reduce the dependence on fossil fuels. Currently, platinum (Pt) based materials have proven to be the most efficient electrocatalysts for the oxygen reduction reaction (ORR) at the cathode of the PEMFC and AEMFC. However, the high price and the limited reserve of Pt greatly hinder their industrial applications. Recently, transition metal‐nitrogen‐carbon (M−N−C) based material, as an efficient alternative to replace the precious metal Pt‐based material, has attracted researchers’ attention. Great contributions have been devoted to develop M−N−C based electrocatalysts. This review summarizes recent advances on M−N−C based electrocatalysts used for ORR from the point view of morphology. One‐dimensional (1D), two‐dimensional (2D), three‐dimensional (3D) and multi‐dimensional (MD) M−N−C materials were discussed thoroughly with particular attention on the relationship between the structure and the catalytic activity.

Transition metal–carbon–nitrogen catalysts for the oxygen reduction reaction (ORR) are promising and challenging. Cu is a potential transition metal to form efficient ORR catalysts for fuel cells. Herein, a facile method is developed to synthesize a highly dispersed Cu−NX and N‐doped graphene (Cu−N−G) catalyst. The Cu−N−G catalyst shows a half‐wave potential (E1/2) of 0.859 V, which is comparable to the commercial Pt/C catalyst (0.856 V), and is among the best compared with the previously reported Cu‐based materials. In addition, such a catalyst shows good stability and methanol tolerance in alkaline media. A synergy of doped N (pyridinic and graphitic N) and Cu−NX moieties as well as the pore structure are revealed to account for the enhanced ORR activity.
