Oil–water separation membranes easily fail to oil foulants with low surface energy and high viscosity, which severely limits these membranes’ applications in treating oily wastewater. Herein, an oil–water separation membrane by bioinspired bubble‐mediated antifouling strategy is fabricated via growing hierarchical cobalt phosphide arrays on stainless steel mesh. The as‐prepared membrane is superhydrophilic/superaerophobic and electrocatalytic for hydrogen evolution under water, which helps to rapidly generate and release abundant microbubbles surrounding the oil‐fouled region on the membrane. These microbubbles can spontaneously coalesce with the oil foulants to increase their buoyancy and warp their interface tension by morphing the oil shape. And this spontaneous coalescence also increases the kinetic energy of oil foulants resulting from the decreased bubbles’ interface energy and potential energy. The synergy of the warped interface tension, increased buoyancy, and kinetic energy drives the efficiently dynamic antifouling of this membrane. This dynamic antifouling even can remove some solid sediment such as oily sand particles that causes more serious fouling of the membrane. Thus, this membrane maintains high flux (>11920 L m−2 h−1 bar−1) in the long‐term separation of oil–water and oil–sand–water emulsions by dynamically recovering the decayed flux on demand, which exhibits great potential in treating industrial oily wastewater.

Metalloenzyme-like metal–nitrogen–carbon (M–N–C) single-atom catalysts (SACs) have received increasing attention in the synthesis of fine chemicals because of the abundant atomic sites and versatile catalytic properties. However, the organic transformations with high atom efficiency over SACs in aqueous media were less investigated. Inspired by the hydrophobic pockets of the metalloenzyme, herein we introduced a hydrophobic, atomically dispersed Pd catalyst (Pd1–S–C) in the sulfur-doped carbon based on metal–sulfur coordination chemistry. This hydrophobic Pd-based SAC displayed satisfying catalytic performance for aqueous-phase semihydrogenation of terminal alkynes with high chemoselectivity, friendly substrate scope, and fairly good stability. Molecular dynamics simulations revealed that the hydrophobicity of the Pd1–S–C catalyst could contribute to accelerated reaction kinetics by enriching the organic alkynes around the catalytic sites in aqueous media. Furthermore, the electron-rich PdS4 single sites were demonstrated to promote activation of H2 molecules and desorption of CC intermediates, which outperformed the electron-deficient PdN4 single sites. The current work highlights the potential of enzyme-inspired hydrophobic SACs in the conversion of organic substrates in aqueous media.
