Hierarchically wood-derived integrated electrode with tunable superhydrophilic/superaerophobic surface for efficient urea electrolysis

Recent development and emerging applications of robust biomimetic superhydrophobic wood

“…For instance, Liao et al devised a wood-derived integrated electrocatalytic electrode (Ni/ CW) with tailored surface wettability for the urea oxidation reaction (UOR). 130 The wood electrode showed tunable superhydrophilic/superaerophobic surface characteristics due to the embedded and evenly distributed papillary nickel nanoparticles in the inner wall of the pore channels in the wood. This leads to superior UOR catalytic performance in alkaline electrolytes.…”

Hierarchical porous NiFe-P@NC as an efficient electrocatalyst for alkaline hydrogen production and seawater electrolysis at high current density

“…The super-hydrophilic nature of the electrodes facilitated close contact with the electrolyte, and thus maximized the active surface area and accelerated the reaction kinetics. [75][76][77] The HER activity of the synthesized samples was evaluated in a typical three-electrode system in KOH solution (1.0 M). As shown in Fig.…”

Bioinspired Gas Manipulation for Regulating Multiphase Interactions in Electrochemistry

“…Based on the bubble manipulation strategy, researchers have made significant advancements in the development of various electrodes, for example, superaerophobic electrodes, [54,[56][57][58][59][63][64][65][66][67][68][69][70][71][72][73][74][75] (super)aerophilic electrodes, [27,18,60,[76][77][78][79][80][81][82] asymmetric electrodes, [37][38][39][83][84][85] and other electrodes that facilitate gas transport [40][41][42][43]86] in a wide range of gas-related reactions (Table 1). Among the various reactions, HER and CO 2 RR Table 1.…”
