“…When the current density reaches 10 mA cm À2 , the overpotential of the sample in 1 M KOH solution was 340 mV. This overpotential compares favourably with the behaviour of Cu-based OER electrocatalysts, except FeS x /CF composites such as Fe(OH) 3 : Cu(OH) 2 /CF ($365 mV), 43 Co-CoO@3DHPG ($410 mV), 44 FeN x /carbon ($320 mV), 45 NiS/ NC ($371 mV), 46 and 2D CuO nanosheet bundles ($350 mV), 47 etc. A more detailed comparison is given in Table 1.…”

“…In this case, the potential window of 0.036–1.164 V versus reversible hydrogen electrode (RHE) was chosen to avoid the Faradaic redox occurred during the CV measurement. Based on the CV curves, the EDLC of these Mn@HNCNTs samples can be calculated via the method reported by Wang and co‐workers and shown in Figure . As expected, the Mn@HNCNTs‐2 has a high capacitance of 511.3 F g −1 , much higher than the other three samples, indicating that there are more electrochemical active sites available on Mn@HNCNTs‐2.…”

The practical application of clean energy conversion and storage technologies, such as fuel cells and metal-air batteries, have been significantly impeded by the high cost and scarcity of precious metal catalysts used for the oxygen reduction reaction (ORR). Transitional metal/carbon compounds are a promising alternative to precious metal catalysts for the ORR. Herein, Mn nanoparticles encapsulated within mesoporous helical N-doped carbon nanotubes (Mn@HNCNTs) are developed as highly active ORR catalysts. In terms of the onset potential and half-wave potential for ORR, the optimized Mn@HNCNTs exhibit an excellent ORR performance, which is comparable to Pt/C. When the Mn@HNCNTs are assembled as air cathodes, with zinc foil as the anode in primary zinc-air cells, the obtained cell delivers a higher cell voltage and capacity than the zinc-air cell using Pt/C as the air cathode, as well as many reported cells using TM/ CNT-based air cathodes. The electrocatalytic performance in the zinc-air cell demonstrates that Mn@HNCNTs have great potential for use as ORR catalysts in metal-air batteries.

“…This is evident from the amount of literature being published in the sulfide domain. [ 180,184–193 ] The easy generation of S–H ads bonds and contribution of unsaturated sulfur atoms in catalytic activity improves catalytic HER of sulfides. [ 194 ] However, various problems are associated with the electrocatalytic performance in metal‐sulfide based photocatalysts.…”

Nickel chalcogenide (S and Se) based nanostructures intrigued scientists for some time as materials for energy conversion and storage systems. Interest in these materials is due to their good electrochemical stability, eco‐friendly nature, and low cost. The present review compiles recent progress in the area of nickel‐(S and Se)‐based materials by providing a comprehensive summary of their structural and chemical features and performance. Improving properties of the materials, such as electrical conductivity and surface characteristics (surface area and morphology), through strategies like nano‐structuring and hybridization, are systematically discussed. The interaction of the materials with electrolytes, other electro‐active materials, and inactive components are analyzed to understand their effects on the performance of energy conversion and storage devices. Finally, outstanding challenges and possible solutions are briefly presented with some perspectives toward the future development of these materials for energy‐oriented devices with high performance.
