“…[ 21 ] Although great progress has been made in the preparation and performance of non‐noble metal ORR catalysts for proton exchange membrane fuel cells, there are still many challenges. [ 22 ] Under acidic conditions, most catalysts struggle to outperform commercial Pt/C catalysts. Therefore, it is still a challenge to improve the activity and durability of catalysts under different conditions.…”

Coal gasification fine slag (GFS) is a kind of solid waste that is produced from industrial entrained‐flow gasification plants. Using the GFS flotation residue as a carbon source for the oxygen reduction reaction (ORR) catalyst is therefore an effective recycling method that will gain great attention. Herein, the carbon residue after the flotation of GFS is used as the precursor to prepare ORR catalysts through CO2 activation. Combined with the characterization of Raman spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscopy, the influence of N, P, Fe, Ca, and other doped elements on the physical and chemical structure of the catalyst is explored. The results demonstrate that calcium chloride causes the decrease of reactive nitrogen, and has a negative effect on the development of pore structure. The active nitrogen content of ammonium phosphate as a nitrogen source is lower than that of ammonium chloride as a nitrogen source. The codoping of ammonium phosphate and ferrocene produces a mutual inhibitory effect, resulting in lower doping levels of phosphorus and iron. This study has great significance for the activation and heteroatom doping treatment of ORR catalysts prepared from gasification residue carbon.

“…Transition metal-based catalysts, metal-organic frameworks (MOFs), and carbon-based materials are being studied as alternatives with promising electrocatalytic properties. [20] For example, the development of MOF derivatives for electrocatalysts in zinc-air batteries. Zinc-air batteries have a relatively high energy density, which means they can store more energy in a relatively small volume and weight, making them a potential advantage in energy storage and battery applications.…”

As a clean energy conversion technology, hydrogen fuel cell has great development prospect in the field of sustainable energy. Scientists have been working on the design and optimization of hydrogen fuel cells to make the efficiency and performance higher. This article introduces the main directions and methods of designing and optimizing hydrogen fuel cells. First, the design of hydrogen fuel cell mainly depends on the which catalyst materials you choose and catalyst active sites. For example, precious metal catalysts, transition metal catalysts, and catalysts of nanostructured materials all make a huge impact on battery performance. Improving the activity and stability of catalyst and reducing the cost is one of the key points of this design. In addition, optimizing of the electrolyte film to improve the efficiency and battery life is also key. By taking the above factors into consideration and using advanced materials and technologies, hydrogen fuel cells can achieve high efficiency, high performance, and long life, and promote their commercial application.

“…Additionally, it has been shown that these materials are stable for up to hundreds of hours under alkaline conditions. Despite the tremendous advancements, the stability times are not satisfactory compared to the thousands of hours target established by the US Department of Energy [84] . To fulfil such a long‐term stability target, further studies are required to help design more suitable Fe−N−C and Co−N−C catalysts.…”

Electrocatalytic reduction of small molecules such as dioxygen (O2), carbon dioxide (CO2), and water has driven conspicuous attention due to their technological importance and capability of tackling current environmental issues. So far, to drive such reactions, catalysts based on the platinum‐group elements have displayed the best performance, however, the high‐cost and scarcity of these elements hinder large‐scale applications. Alternatively, earth‐abundant M−N−C (M=Fe, Co, or Ni) materials have stood out as potential candidates because of their suitable electrocatalytic properties for the aforementioned reactions. In this way, the present review aims to provide a thorough account of the recently reported strategies to improve the electrocatalytic reduction of O2, CO2, and water on M−N−C catalysts. In order to have an in‐depth understanding of these reactions, we will also discuss some of the latest theoretical studies based on computer modelling and simulation. Lastly, additional comments on future perspectives will be provided to guide new studies.
