Figure 6. Ru/MXene 3D electrode with superhydrophilicity and superaerophobicity for overall water splitting. (A) the synthesis process of Ru/c-Ti₃C₂T_x/NF electrode; (B) the contact angles of water droplets and underwater contact angles of gas bubbles, the digital images of bubble generation behavior and the corresponding fluid velocity vector field of the electrolyte on NF, Ru/NF, c-Ti₃C₂/NF, and Ru/c-Ti₃C₂/NF electrodes; (C) overall water-splitting performance of Ru/c-Ti₃C₂/NF//Ru/c-Ti₃C₂/NF and RuO₂/NF//Pt-C/NF at 5 mV·s^-1 in 1.0 M KOH; (D) durability of Ru/c-Ti₃C₂/NF//Ru/c-Ti₃C₂/NF as demonstrated by chronoamperometry at 10 mA·cm^-2.
