Autonomous and intrinsic self-healing Al2O3 membrane employing highly-wetting and CO2-selective molten salts

In this work, a new autonomous self-healing membrane was described and evidenced. Carbon was included in the structure of a ceramic/molten salt composite membrane and subsequently oxidised to create voidage. Through the spreading of the highly-wetting molten salt, an autonomous self-healing membrane was evidenced for the first time.
