Bioinspired synthesis of hierarchical macro-mesoporous titania with tunable macroporous morphology using cell-assemblies as macrotemplates

摘要

Cell-assemblies with different cell shapes were used as macro-templates in the bioinspired synthesis of hierarchical macro-mesoporous titania with tunable macroporous morphology and enhanced photocatalytic performance.rnPorous materials are cnown to feature large surface areas and connected pore channels, which can be used in numerous applications including catalysis, sorbents, separations, fuel cells, microelectronics, sensors, and medical diagnosis. Recently, hierarchical pore materials with macropores along with micro- and/or mesoporcs have gained significant attention since they combine the advantages of all the pore systems." The presence of macropores can act as a transport system for liquids and gases, thus increasing the accessibility of the smaller pores, especially improving the flow rates at high back pressure. These smaller pores with high surface area will greatly enhance the host-guest interactions, selectivity, and catalytic or ion-exchange properties.
