“…Both experimental and theoretical results indicate the super‐assembled MCS/AAO hybrid membrane displays excellent cation selectivity due to the ultra‐small and uniform pore size [15] . Excellent ion selectivity is a crucial element of RED nanofluidic devices, [30] therefore, MCS/AAO hybrid membrane has great potential for salinity gradient energy harvesting.…”

Nanofluidic devices have been widely used for diode‐like ion transport and salinity gradients energy conversion. Emerging reverse electrodialysis (RED) nanofluidic systems based on nanochannel membrane display great superiority in salinity gradient energy harvesting. However, the imbalance between permeability and selectivity limits their practical application. Here, a new mesoporous carbon‐silica/anodized aluminum (MCS/AAO) nanofluidic device with enhanced permselectivity for temperature‐ and pH‐regulated energy generation was obtained by interfacial super‐assembly method. A maximum power density of 5.04 W m−2 is achieved, and a higher performance can be obtained by regulating temperature and pH. Theoretical calculations are further implemented to reveal the mechanism for ion rectification, ion selectivity and energy conversion. Results show that the MCS/AAO hybrid membrane has great superiority in diode‐like ion transport, temperature‐ and pH‐regulated salinity gradient energy conversion.

“…Bionic ion channels with asymmetric structures also show excellent energy conversion performance [ 116 ]. The asymmetric membrane with an ion diode effect can be used as an energy conversion generator component to assist one-way ion transport in the channel [ 117 ]. Therefore, the energy conversion efficiency is higher than that of a symmetric membrane.…”

Hydrogel is a type of crosslinked three-dimensional polymer network structure gel. It can swell and hold a large amount of water but does not dissolve. It is an excellent membrane material for ion transportation. As transport channels, the chemical structure of hydrogel can be regulated by molecular design, and its three-dimensional structure can be controlled according to the degree of crosslinking. In this review, our prime focus has been on ion transport-related applications based on hydrogel materials. We have briefly elaborated the origin and source of hydrogel materials and summarized the crosslinking mechanisms involved in matrix network construction and the different spatial network structures. Hydrogel structure and the remarkable performance features such as microporosity, ion carrying capability, water holding capacity, and responsiveness to stimuli such as pH, light, temperature, electricity, and magnetic field are discussed. Moreover, emphasis has been made on the application of hydrogels in water purification, energy storage, sensing, and salinity gradient energy conversion. Finally, the prospects and challenges related to hydrogel fabrication and applications are summarized.
