The development of membrane science plays a fundamental role in harvesting osmotic power, which is considered future clean and renewable energy source. However, the existing designs cannot handle low conversion efficiency power density. Theory has predicted that Janus with ionic diode-type current would be most efficient material. Therefore, rectified transportation hypersaline environment (the salt concentration at least 0.5 M sea) highly desired, but it still remains challenge. Here, we...
