3D macroporous hierarchical Ag-G-NCF can efficiently convert CO ₂ to ethanol with a low overpotential, high faradaic efficiency and high selectivity.

1D/2D NR/CS-X displayed an excellent electroreduction CO₂ performance with low onset overpotential and high Faraday efficiency, impressive stability and fast kinetics.

This is the first example of synergistically assembled Gr/ZnO sheets to improve the corrosion protection properties of WEP coatings, and Gr_0.04–ZnO_0.4 exhibited the highest impedance of 200 530 Ω cm² compared to pure WEP of 6186 Ω cm².

Nitrogen‐doped carbon nanotubes (NCNTs) are usually selective and robust electrocatalysts for CO₂ reduction to CO in aqueous media. However, the electronic property of NCNTs is strongly dependent on their curvature, the change of curvature has a great impact on the electrocatalytic performance. Therefore, it is highly desirable to clarify the curvature effect of NCNTs for CO₂RR performance. Herein, we investigated the CO₂RR performances of NCNTs with different curvatures, which were obtained by doping N into CNTs under high temperatures. And low curvature of l‐NCNT‐1000 presented the highest CO FE (88.5%), which was much higher than that of the mid curvature of M‐NCNT‐1000 (71.1%) and the high curvature of S‐NCNT‐1000 (58%). According to density functional theory (DFT) calculations, the pyridine‐N site was considered a catalytic active site for CO₂RR regardless of the low, mid or high curvature structure. Moreover, the low curvature surface of NCNTs had a relatively large binding energy with the HOCO* intermediate that is the principal intermediate for the CO₂RR, thereby enhancing the catalytic activity of CO₂ electroreduction to CO.

In order to broaden the selectivity of graphite nanosheet additives on epoxy resin-based coatings and verify the size effect, this work aims to dope graphite nanosheets of different sizes into the three-dimensional structure produced by cross-linking and curing epoxy resin and polyamide resin. In addition, a micro-nano level secondary structure and a surface with special roughness are constructed to obtain the composite epoxy hydrophobic coating. The influence of the size effect of graphite nanosheets on the hydrophobic performance and corrosion resistance of the coating is summarized as well. Among them, the optimized doping size (2.2 μm) of graphite nanosheets in the epoxy coating showed the largest impedance arc of 2.58 × 10⁸ Ω cm², which could form an excellent nano-network covering the micropores to impede the diffusion of corrosive medium. Through simulation calculation analysis, we also found that the edge site of graphene is more effective in capturing H₂O and O₂; therefore, a smaller size of graphene with a large edge can be more favorable. This work will be used as a reference for the industrial application of graphite anti-corrosive coating.
