“…When the loading is overloaded, the activity falls dramatically. Because of the oxygen reduction process, the following two steps might exist: (1) from O 2 to H 2 O 2 and (2) from H 2 O 2 to H 2 O [19]. To some extent, the conclusion summarized by Bezerra et al [24] might also explain our results.…”

“…Carbon-supported metal N4-macrocycles are generally prepared via pyrolysis method [24] and are primarily used as oxygen electroreduction catalyst for proton exchange membrane (PEM) fuel cells [19,[23][24][25][26] and also investigated as catalysts for H 2 O 2 electroreduction. Raman et al [18] investigated FeTMPP/C as the cathode catalyst for direct borohydridehydrogen peroxide fuel cell.…”

Fe-N-C catalysts were prepared through metal-assisted polymerization method. Effects of carbon treatment, Fe loading, nitrogen source, and calcination temperature on the catalytic performance of the Fe-N-C for H 2 O 2 electroreduction were measured by voltammetry and chronoamperometry. The Fe-N-C catalyst shows optimal performance when prepared with pretreated active carbon, 0.2 wt.% Fe, paranitroaniline (4-NA) and one-time calcination. The Fe-N-C catalyst displayed good performance and stability for electroreduction of H 2 O 2 in alkaline solution. An Al-H 2 O 2 semi-fuel cell was set up with Fe-N-C catalyst as cathode and Al as anode. The cell exhibits an open-circuit voltage of 1.3 V and its power density reached 51.4 mW cm −2 at 65 mA cm −2 .

“…[200][201][202] Metalloporphyrins have been often used to promote the four-electron reduction, [201,203] although problems of stability exist. The alternative and preferable approach is to introduce a cocatalyst active for the decomposition of H 2 O 2 (DHP) to water and oxygen.…”

The Role of Nanostructure in Improving the Performance of Electrodes for Energy Storage and Conversion

2009

The nanostructure is a critical element to improve the performance of electrodes and realize the demanding expectation for a more sustainable and efficient conversion and storage of energy. This microreview analyzes some examples related to advanced electrodes for Li-ion batteries, PEM fuel cells, titania photoanodes and solar cells. The role of a proper nanoarchitecture and hierarchical organization in the electrode, which requires the understanding of the complex physicochemical phenomena occurring at the nanoscale level, is discussed. The need to use cost-effective methods for

“…In the short term, catalysts containing low amounts of Pt are practical, but in the long term, non-noble metal catalysts would be the better solution. Up to now, most research has focused on heat-treated metal-N4 macrocycles, especially Fe-and Co-N4, which are believed to be the most promising Pt-free catalysts [1][2][3][4][5][6][7][8][9][10][11][12]. These catalysts have shown promising but still quite low activity towards fuel cell reactions, compared with those of Pt catalysts.…”

Hexamethylenetetramine was used as nitrogen resource to prepare platinum-free Fe-N and Co-N electrocatalyst for oxygen reduction reaction (ORR). X-ray diffraction measurement shows that trace Co ions are reduced to Co metal. Cyclic voltammogram experiment shows that the ORR peak potential appears at 200 mV (vs. SCE) in oxygen-saturated acidic media. The Koutecky-Levich analysis indicates that the ORR follows the first-order kinetic reaction and the ORR proceeds mainly via the four-electron reduction.
