Summary: Recent research has found that platinum group metal-free oxygen reduction reaction catalysts show potential as alternatives to Pt-based catalysts in polymer electrolyte fuel cells, but their durability and stability issues remain. Only electrochemical techniques, such as square wave voltammetry and Fourier transform alternating current voltammetry, are suitable for accurate measurement of active site density in these catalysts.

Summary: Atomically dispersed M-N-C catalysts are promising PGM-free cathode catalysts for ORR. Increasing the density of accessible active sites is crucial for enhancing the ORR performance. A highly porous PPy hydrogel was reported as a versatile support for the facile design of a Co-N-C electrocatalyst. The resulting Co-N-C catalyst showed excellent stability, with a high half-wave potential and low H2O2 yield.

Summary: Two new azo reactive disperse dyes were synthesized using cyanuric chloride as a reactive component for dyeing nylon fabric. The dyes were characterized and their structures confirmed by various analytical techniques. The dyes demonstrated good color uniformity and build-up on nylon 6 and wool fabrics, and showed higher color yield compared to corresponding disperse dyes. However, their fastness properties were lower than those of reactive disperse dyes due to limited reaction with the fabric surface.

Summary: Defect engineering is crucial for electrocatalysts, especially for ultrathin nanosheets of transitional metal compounds with high surface to bulk ratio that can be engineered along the grain boundaries. In this study, we developed super-thin and ordered face-centered cubic VN nanosheets with grain boundaries using a facile and in-situ method. The prepared samples showed significant temperature-dependent sheet distribution, and the thickness of the nanosheets was found to be crucial for electrochemical reactions. The VN nanosheets demonstrated interesting oxygen reduction reaction performance with high onset potential and durability, highlighting the importance of surface engineering in electrocatalyst performance for potential practical applications.

Summary: This study investigates the effect of introducing S or P atoms into N coordination on the electronic structure and catalytic performance of FeN4 SACs. It demonstrates that FePN3 can effectively activate O-2 and promote ORR, while FeSN3 is beneficial to H2O activation and OER. Both FePN3 and FeSN3 exhibit outstanding stability. The N,P and N,S co-coordination provides a better catalytic environment for SACs in ORR and OER.

Summary: Proton-exchange-membrane fuel cells (PEMFCs) are sustainable, renewable, efficient, and eco-friendly energy conversion systems, but their performance is hindered by sluggish oxygen reduction reactions. Recent efforts have been focused on exploring transition metal and hetero-atom doped carbon materials, with Co-N doped meso/microporous carbon catalysts showing outstanding oxygen reduction activity in an alkaline medium. This catalyst exhibits high activity, long-term stability, and methanol tolerance, making it a promising non-precious metal-based ORR catalyst for PEMFCs.

Summary: The study showed that in alkaline conditions, the coordination of iron with pyridinic-N and high carbon surface area can enhance the ORR activity. In acidic media, a reasonable relationship was established between Fe-N-x coordination (pyridinic-N) and pyrrolic-N contents and the ORR activity of catalysts.
