Abstract Sustainable alternatives for the energy intensive synthesis of H 2 O are necessary. Molecular cobalt catalysts show potential but typically restricted by undesired bimolecular pathways leading to breakdown both and catalyst. The confinement porphyrins in PCN‐224 metal‐organic framework leads an enhanced selectivity towards stability Consequently, oxygen can now be selectively reduced hydrogen peroxide with a stable conversion at least 5 h, illustrating confined MOFs increase electrocatalytic conversions.

Abstract Ammonia (NH 3 ) is an important raw material in the chemical industry, but synthesis of NH by traditional Haber‐Bosch process will increase carbon footprint. Therefore, it necessary to develop sustainable routes for production. New production schemes, including nitrogen reduction (N 2 RR), nitrite (NO and nitrate have been proposed. Porphyrins phthalocyanines are macrocyclic compounds with a central metal ion coordinated nitrogen. The centers these catalysts play crucial role binding activating nitrogen, nitrite, nitrate. Their unique structure allows effective electron transfer catalytic activation synthesis. Recently, porphyrin phthalocyanine based demonstrated be efficient catalyzing N RR, NO RR. Unfortunately, there no review focusing on such electrocatalytic . In this review, we discuss performances summarize key factors reaction mechanisms that affect performance catalyst systems. This helps design more new electrocatalysts

Abstract A bio‐inspired FeFe hydrogenase model which catalyses hydrogen evolution reaction (HER) in acidic solutions is immobilized polyaniline (PANI)‐based nanotubes. combination of analytical techniques reveals that this construct maintains both the molecular signatures complex and material properties PANI. The amine imine‐rich environment PANI chain amplifies inherent HER activity complex, allowing electrocatalytic at neutral pH, with lower overpotentials higher current densities compared to alone. This retains oxygen stability remains stable through several hours aerobic electrolysis, producing only 6.5 % H₂O₂ from competing reduction (ORR).
