Heterogeneous molecular catalysts built from β-substituted cobalt porphyrins and carbon nanotubes afford tunable activity for H 2 O synthesis via the two-electron transfer oxygen reduction reaction.
Surface oxidized carbon nanotubes (o-CNTs) can produce sustainable hydrogen peroxide (H2O2) by the two-electron transferred oxygen reduction reaction (2e-ORR). The C atoms neighboring to surface epoxy (C–O–C) groups are recognized as active sites. Herein, we report CNT curvature, or diameter, dependent ORR activity of o-CNT catalysts. Computation modeling suggests that curvature alter group geometry, exerting greater strain on C–O bond in smaller diameter o-CNTs leads improved activity. This...
Abstract Understanding the spin‐dependent activity of nitrogen‐coordinated single metal atom (M‐N‐C) electrocatalysts for oxygen reduction and evolution reactions (ORR OER) remains challenging due to lack structure‐defined catalysts effective spin manipulation tools. Herein, both challenges using a magnetic field integrated heterogeneous molecular electrocatalyst prepared by anchoring cobalt phthalocyanine (CoPc) deposited carbon black on polymer‐protected magnet nanoparticles, are...
Zinc-ion batteries (ZIBs) are promising energy storage devices with safe, nonflammable electrolytes and abundant, low-cost electrode materials. Their practical applications hampered by various water-related undesirable reactions, such as the hydrogen evolution reaction (HER), corrosion of zinc metal, water-induced decay cathode Polymer hydrogel were used to control these reactions. However, salt, water, polymeric backbones intervene in polymer hydrogels, currently, there no systematic...
Clean hydrogen production via methane pyrolysis (CH4 → 2H2 + C) generates large quantities of solid carbon. Realizing their applications is a critical gap to enable its broader adoption. Here, we show that carbon nano onions encapsulated with iron cores (Fe@CNO) produced in CH4 using low-cost Fe ore catalysts can serve as tri-functional adsorbent and catalyst for organic contaminant degradation. Fe@CNO has high adsorption capacity fast pseudo-second-order kinetics antibiotics wastewater....
Manipulating Single Atom Catalyst Spin State In article number 2408461, Hao Li, Yuan Chen, Li Wei, and co-workers utilize polymer-protected permanent nanomagnets to manipulate the spin state of a single atom catalyst. Without modifying atomic structure, significantly improved oxygen redox reaction performance is observed. This approach applicable other magnetic catalysts, offering new strategy investigate spin-dependent catalytic performance.
