Copper-catalyzed FeOOH templated method for accelerated fabrication of ultraporous membranes used in microalgae dewatering

Porous materials including polymeric and inorganic membranes are important and widely used in various industries. Controlling the pore size and pore distribution in porous materials is the major focus in this field. In this study, a novel copper-catalyzed template dissolution approach using ferric o...
