Edged Donor–Acceptor Engineering in Conjugated Organic Polymers for Cocatalyst‐Free Photocatalytic H2 Evolution

open access: yesEcoEnergy, EarlyView.
A terminal donor–acceptor pair is constructed at the edge of sulfone‐based conjugated polymers to establish intramolecular charge transfer paths. This design activates dual‐role active sites for proton adsorption and electron acceptance, achieving efficient cocatalyst‐free photocatalytic hydrogen evolution through optimized kinetics and tunable D‐A ...

Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

CO2 Conversion Into Energy Rich Fuels Over Nascent COF Decorated‐Lead Free Halide Perovskites Hybrid Nano Catalysts: Experimental and Computational Investigation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A panoramic scheme signifies the CO2 conversion into energy‐rich fuels over nascent COF‐decorated lead‐free halide perovskite hybrid nano‐catalysts. Even though lead‐containing halide perovskites have been deemed emerging materials. However, the presence of toxic and carcinogenic lead (Pb) metal, small surface area, low charge separation, and a high ...
