Porous Zn-based and ZnO composites are successfully fabricated via the sol-gel process and ambient pressure drying (APD) method using hexane as the drying solvent for the reduction of capillary force during drying process. Various highly porous Zn-based phases (Zn1-based and Zn5-based) that are studied by X-ray diffraction analysis, scanning electron microscopy and transmission electron microscopy, show that they contribute through heat treatment (at 200°C) to the development of ambient pressure dried nanoporous wurtzite (hexagonal) ZnO. A macroporous flower-like structure consisting of nanosheets is observed in porous Zn-based composites and nanoporous structure is observed within platelets of ZnO nanoparticles. Possible routes for preparing highly porous Zn-based/ZnO composites are discovered by detailing the process for ambient pressure drying synthesis of porous wurzite ZnO.
