Novel Multifunctional Janus-Type Membrane on Al Anode for Corrosion Protection (Adv. Mater. Interfaces 19/2021)

Janus-Type Membrane for Corrosion Protection In article number 2100786, Ying Yu, Yu-Xin Zuo, Chun-Cheng Zuo, and co-workers develop a multifunctional Janus-type membrane with hydrophobic and anticorrosion abilities on the surface of aluminum. The Janus-type membrane can simultaneously block the invasion of hydroxide ions and water. In Al–air battery it can effectively inhibit the hydrogen evolution reaction and increase the specific capacity. The image is based on the theme of ancient siege-defense, using two layers of walls (i.e., Janus-type membrane) to protect Al electrode.
