Abstract
ABSTRACT Among emerging energy‐harvesting technologies, salinity gradient energy via reverse electrodialysis is a promising route to mitigate energy and environmental pressures. Delignified natural wood framework provides natural ion‐transport channels for osmotic energy harvesting and holds significant promise, yet its low surface‐charge density constrains efficiency. Accordingly, a wood framework/sodium alginate (W/SA) heterogeneous membrane was produced by infiltrating SA, which is rich in negatively charged groups, into the delignified natural wood framework and crosslinking to form a stable, ion‐selective architecture. The W/SA membrane delivers a power density of 14.43 W m − 2 under a 50‐fold NaCl…
