The increase in energy density of the next generation of battery materials to meet the new challenges of the electrical vehicles era calls for innovative and easily scalable materials with sustainable processes. An innovative Cu O/C nanocomposite material, characterized by a highly conductive 3D-framework, with Cu O/Cu-metal contiguous nanodomains is prepared by electrospinning. The electrode processing is made using a polyacrylic acid binder. The nanocomposite has been fully characterized and the electrochemical performance shows high specific capacity values over 450 galvanostatic cycles at 500 mAg specific current with capacity retention values over 80 %. In addition, the composite shows remarkable high rate performance and highly stable interface, which has been studied by impedance spectroscopy.

Visible light photocatalysts hold great promise for water purification, yet research on highly efficient, non-toxic photocatalysts is limited. This study synthesized novel g-CN/AlOOH photocatalytic nanocomposites via thermal condensation, enhancing adsorption and visible light degradation by 36-fold and 11-fold, respectively, compared to g-CN alone. The nanocomposites achieved a 98% removal rate of methyl orange under xenon lamp irradiation (>400 nm) for 1 hour.

Redox-active covalent organic frameworks (COFs) have been demonstrated as promising organic electrodes in many electrochemical devices. However, their inherently low conductivity significantly hinders the full utilization of their internal redox-active sites. To address this issue, a simple solvothermal method is used to in situ polymerize 2,4,6-triformylphloroglucinol (TP) and p-phenylenediamine (PA) on the surface of carbon nanotubes (CNTs), generating a nanocable-like COF-based nanocomposite, TpPa-COF@CNT nanocables, which contain abundant β-ketoenamine groups.
