Dual-bioinspired Janus mesh membrane with controllable bubbles manipulation property for efficient water splitting and pure gas collection.

Water splitting, as a promising clean energy source, has garnered significant attention owing to the escalating global energy crisis. However, prior research has largely focused on electrode materials rather than bubble manipulation, which plays a crucial role in the process. Although using the previously published "Releasing strategy" effectively eliminates micro-sized bubbles from the electrode material for efficient water splitting, the released tiny-sized bubbles pose challenges for controllable and pure collection.

Janus Membranes with Asymmetric Superwettability for High-Performance and Long-Term On-Demand Oil/Water Emulsion Separation.

Current single-function superwettable materials are typically designed for either oil removal or water removal and are constrained by oil density, limiting their widespread applications. Janus membranes with opposite wettability on their two surfaces have recently emerged and present attractive opportunities for on-demand oil/water emulsion separation. Here, a combination strategy is introduced to prepare a Janus membrane with asymmetric superwettability for switchable oil/water emulsion separation.
