“…136 Similar results could be presented by Guan et al who also investigated the ORR activity of dually doped graphene. In their approach, few-layered graphene was doped with N and S at the same time using pyrimidine and thiophene as precursors in the chemical vapour deposition type synthesis of graphene.…”

Heteroatom doped carbon materials represent one of the most prominent families of materials that are used in energy related applications, such as fuel cells, batteries, hydrogen storage or supercapacitors. While doping carbons with nitrogen atoms has experienced great progress throughout the past decades and yielded promising material concepts, also other doping candidates have gained the researchers' interest in the last few years. Boron is already relatively widely studied, and as its electronic situation is contrary to the one of nitrogen, codoping carbons with both heteroatoms can probably create synergistic effects. Sulphur and phosphorus have just recently entered the world of carbon synthesis, but already the first studies published prove their potential, especially as electrocatalysts in the cathodic compartment of fuel cells. Due to their size and their electronegativity being lower than those of carbon, structural distortions and changes of the charge densities are induced in the carbon materials. This article is to give a state of the art update on the most recent developments concerning the advanced heteroatom doping of carbon that goes beyond nitrogen. Doped carbon materials and their applications in energy devices are discussed with respect to their boron-, sulphur-and phosphorus-doping. Broader contextThe research and design of novel materials that are applicable in various energy devices represent one of the central and most thriving subjects within today's scientic work. The challenges do not only rely on the tremendous need to overcome traditional fossil fuel based energy recovery. While a lot of sustainable concepts already exist, these require the development of high performance materials that are able to cope with certain challenges, e.g. the dependence on highly expensive and rather not abundantly available noble metals, and also a lack of long term stability of those. Researchers have been carrying out numerous studies concentrating on nding alternative materials that can be applied in novel energy devices. Those alternative materials should most preferably be free of noble metals, avoid expensive precursor systems, be sustainable and not rely on the fossil energy sources that are to be replaced, and of course exhibit high activity in the devices they are designed for. One class of materials in whose development and understanding researchers have put strong effort is heteroatom-doped carbon materials. By heteroatom doping the properties are altered compared to crude carbon materials. The by far most intensely studied doping candidate is nitrogen, capable of not only increasing electric conductivity, but also the catalytic activity of carbons. Such N-doped carbons have advanced tremendously in the past few years, especially by proving their usefulness as electrocatalysts for the reduction of oxygen in fuel cell cathodes, or as electrode materials in supercapacitors. Meanwhile the spectrum of doping has been widened, and novel doped carbons have been reported, indicating the promising pote...

“…64 DFT calculations indicate that simultaneously incorporating of S and N into graphene induces a substantially uplift of spin density, indicating higher ORR catalytic performance. Recently, Jeon and co-workers prepared a series of heteroatoms (N and/or S) doped graphene in different ratios from various doping precursors (pyridine, thiophene and bithiophene combined separately with dipyrrolemethane as single N and/or S precursor) by thermal reaction.…”

The development of cost-effective, efficient and stable electrocatalysts towards oxygen reduction reaction (ORR) has been an aim to overcome the bottleneck of widespread application of fuel cells and rechargeable metal-air batteries. Unique physicochemical properties of heteroatom-doped graphene open up a brand-new avenue for design and application of metal-free electrocatalysts in these electrochemical devices. Given the flourishing research of graphene and electrochemical energy storage, we critically summarize recent progress in the design, synthesis and application of various heteroatom (N, S, P, B, etc)-doped graphene materials as the electrocatalysts towards ORR. The distinctive properties resulting from various dopants and the resultant electrocatalytic activity are highlighted to gain insights into the mechanism of heteroatom-doped graphene for ORR. We conclude this article with some future trends and opportunities of developing heteroatom-doped-graphene-based electrocatalysts in the application of the ORR-related devices.

In this study, we present a more electrochemically enhanced electrode using activated carbon (AC)-sulfur (S) composite materials, which have high current density. The morphological and micro-structure properties were investigated by transmission electron microscopy. Quantity of sulfur was measured by thermogravimetric analysis analysis. The electrochemical behaviors were investigated by cyclic voltammetry. As a trapping carbon structure, AC could provide a porous structure for containing sulfur. We were able to confirm that the AC-S composite electrode had superior electrochemical activity.
