Abstract Aqueous instability, poor ion selectivity, and high internal resistance limit osmotic energy harvesting in nanofluidic membranes. This study develops a novel composite membrane combining 2D SnO2 and vermiculite (VMT) nanosheets to enhance permeability and ion selectivity, boosting power density. The optimized membrane achieves an output power density of 0.727 W m⁻² using simulated saltwater/river water, offering a promising solution for efficient osmotic energy conversion.
