Insights into the Origins of Solar‐Assisted Electrochemical Water Oxidation in Allotropic Co5.47N/CoN Heterojunctions

ENERGY &ENVIRONMENTAL MATERIALS, Volume 7, Issue 5, September 2024.
A distinct mechanism under convergent solar irradiation: The high energic ultraviolet light facilitates the Co3+/4+ conversion process besides common Co2+ emission from the photoelectric effect. More importantly, visible light can generate a photothermal effect, achieving Co2+ excitation and Co3+/4+ conversion either, promoting the OER significantly ...

Decoration of Ag Species into Reduced Graphene Oxide Foam as a Superelastic and Robust Host toward Stable Zn Metal Anodes under Dwell‐Fatigue Condition

Advanced Materials, Volume 36, Issue 33, August 15, 2024.
Ag decorated reduced graphene oxide foam (AGF) is designed as a Zn host for Zn metal anodes under dwell‐fatigue condition through a wet‐press dual‐templating assembly strategy. Owing to high mechanical strength and strong synergetic effect, the AGF host demonstrates remarkable superelasticity and robustness.

Conversion of LiPSs Accelerated by Pt‐Doped Biomass‐Derived Hyphae Carbon Nanobelts as Self‐Supporting Hosts for Long‐Lifespan Li–S Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 7, Issue 3, May 2024.
Benefited from the synergistic catalytic effect and the unique structures, the as‐prepared PtHCNB/MWCNT/S cathodes show long cycle performance with a high S loading. Rechargeable Li–S batteries (LSBs) are emerging as an important alternative to lithium‐ion batteries (LIBs), owing to their high energy densities and low cost; yet sluggish redox kinetics ...
