Abstract
An aluminum oxide-supported polypyrrole-modified oxidized graphitic carbon nitride (α-AlO@PPy/O-g-CN) membrane includes two layers: a first layer including alumina and a second layer including an oxidized graphitic carbon nitride and a polymerized pyrrole. The carboxylic groups and hydroxyl groups of the oxidized carbon nitride interact via electrostatic interactions with polar groups in the polymerized pyrrole. The second layer is a nanofibrous mass including entangled nanofibers. The second layer has a thickness in of 1 to 3 μm.
