Growing ordered CuO nanorods on 2D Cu/g-C3N4 nanosheets as stable freestanding anode for outstanding lithium storage

Hemdan S. H. Mohamed et al.

Summary: In this work, ordered CuO nanorods were grown on 2D Cu/g-C3N4 nanosheets to form hierarchical CuO@Cu/g-C3N4 nanorods film, which exhibited excellent lithium storage performance. The outstanding stability and cyclic performance of this freestanding anode were attributed to the unique 2D nanostructure, ordered CuO nanorods, Cu nanosheets, and porous g-C3N4 nanosheets, providing large exposed area for Li+ insertion, pathways for charge and Li+ transfer, electrons transport, and active sites for Li+ transport and accommodating volume change. This strategy of growing ordered nanostructures on 2D nanosheets is considered an effective way to enhance transition metal oxides for advanced lithium-ion batteries.

Coordination interaction boosts energy storage in rechargeable Al battery with a positive electrode material of CuSe

Gangyong Li et al.

Summary: In this study, a coordination adsorption strategy was employed using CuSe as a positive electrode material to enhance cycling stability and rate capability. Ex situ X-ray photoelectron spectroscopy revealed reversible redox reactions of Cu and Se species, while electron microscopy measurements showed capacity deterioration due to the dissolution of active Cu and Se species. Theoretical calculations identified strong coordination interaction between nitrogen-doped reduced graphene oxide and active species as key in suppressing shuttle effects and achieving excellent cycling stability.

Transformations of Ionic Nanocrystals via Full and Partial Ion Exchange Reactions

Masaki Saruyama et al.

Summary: Elaborate chemical synthesis methods allow the production of inorganic nanocrystals with uniform shape and size distributions. Ion exchange reactions for ionic nanocrystals have been extensively studied due to the large surface-to-volume ratio of the nanoparticles. The cation exchange reactions proceed much faster than anion exchange reactions due to the larger ionic radii of anions within the frameworks of nanocrystals.

Nitrogen doping-mediated oxygen vacancies enhancing co-catalyst-free solar photocatalytic H2 production activity in anatase TiO2 nanosheet assembly

Mohamed Esmat et al.

Summary: Introducing oxygen vacancies (Vo) into TiO2 photocatalyst along with N doping is proposed as an alternative strategy for achieving efficient co-catalyst-free solar photocatalytic activity under less extreme conditions. The synthesized material exhibits good co-catalyst-free solar photocatalytic activity for hydrogen evolution via water splitting under irradiation with simulated solar light, showing higher efficiency compared to typical co-catalyst-free defective TiO2 materials. The introduced Vo is believed to play a role in facilitating charge separation and improving photocatalytic efficiency.
