Abstract

Fabrication of a new macroporous calcium carbonate nanocomposite is demo­nstrated using calcium carbonate hexahydrate. Magnetite nanoparticles are incorporated into the highly hydrated carbonate precursor and microwaving is used to convert the crystals into polycrystalline, vaterite blocks with open nano­architectures and retention of the original dimensions. Co-catalyst activity of the composite material is demonstrated for photocatalytic water oxidations.
