Summary: In this study, nitrogen-doped metal-free catalysts were obtained through nitric acid activation of carbon samples based on Chlorella Vulgaris microalgae, showing seven-fold improvement in catalytic activity compared to C-KOH catalyst. These catalysts were effectively used to produce hydrogen from the methanolysis reaction of sodium borohydride, with hydrogen generation rate values of 3250 and 20100 mL min(-1) g(-1) for C-KOH and C-KOH-N catalysts, respectively. The results demonstrate a new alternative strategy for producing specific heteroatom-doped metal-free carbon catalysts for efficient hydrogen production in an environmentally friendly manner.

Summary: The production and handling of hydrogen energy is crucial for achieving a sustainable hydrogen economy. Ammonia electrooxidation reaction (AER) is considered an effective method for high-performance hydrogen energy application, but its efficiency is affected by low temperature and the cost of electric source and catalytic efficiency. Designing nanocatalysts with unique surface chemistry, electronic structure, electroactive sites, and conductivity is important for enhancing their activity and stability in AER. Studying the AER kinetics and mechanism on nanocatalyst surface can provide insights for commercialization. This review summarizes recent NH3-to-H-2 technologies and discusses the development and potential commercialization of nanocatalysts for hydrogen production via AER.

Summary: This study demonstrates that NbB2 nanoflakes exhibit excellent selectivity and durability in ambient electrochemical N-2 reduction reaction, leading to efficient NH3 production. The high selectivity is attributed to the presence of abundant active vacancies on the surface, which makes the N-N triple bonds in N-2 molecule easier to break for NH3 production.
