A new dendritic dispersant of carbon nanotubes (CNTs) was synthesized and applied for the noncovalent functionalization of single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). The 1,10-bis(decyloxy)decane core of the poly(amidoamine) dendrimer strongly adhered to the sidewalls of CNTs to form CNT/dendrimer supramolecular nanocomposites having many carboxyl groups (–COOH) on the surface. Then, crystallization of calcium carbonate (CaCO3) by the CO2 diffusion technique in aqueous environments using the CNT/dendrimer supramolecular nanocomposites as scaffolds afforded monodisperse spherical CNT/CaCO3 nanohybrids consisting of CNTs and calcite nanocrystals. The morphologies of the SWCNT/CaCO3 hybrids and MWCNT/CaCO3 hybrids were almost the same.

The nanoarchitectonic composites mixed-ZnPc-fMWCNT and linked-ZnPc-fMWCNT were prepared through tetra-[α-(p-amino)benzyloxyl]phthalocyanine Zinc(II) (ZnPc) mixed and covalently linked to multiwalled carbon nanotubes (MWCNTs), respectively. Various spectroscopic methods were used to identify the nanocomposites formed between ZnPc and MWCNTs whether by π–π interaction or by covalent linking. Their photocatalytic properties were fully investigated by carrying out the photodegradation of Rhodamine B (RhB) in aqueous solution under visible light irradiation. The nanocomposites displayed excellent photocatalytic performance, with the photodegradation efficiency as high as 94% for linked-ZnPc-fMWCNT and 83% for mixed-ZnPc-fMWCNT within 3 h irradiation. The repetition test revealed that both nanocomposites have excellent stability and recyclability, and then they are promising candidates as eco-friendly photocatalysts for degradation of organic dyes in aqueous environments.
