Light-driven directional ion transport for enhanced osmotic energy harvesting. [PDF]

Natl Sci Rev, 2021
Abstract Light-driven ion (proton) transport is a crucial process both for photosynthesis of green plants and solar energy harvesting of some archaea. Here, we describe use of a TiO2/C3N4 semiconductor heterojunction nanotube membrane to realize similar light-driven directional ion transport performance to that of biological systems ...

Bio-inspired Nanocomposite Membranes for Osmotic Energy Harvesting [PDF]

Joule, 2020
Summary Osmotic energy represents a widespread and reliable source of renewable energy with minimal daily variability. The key technological bottleneck for osmotic electricity is that membranes must combine highly efficient ion rectification and high ionic flux with long-term robustness in seawater.
