Halloysite (HNT) is a 1:1 ratio aluminosilicate multi-walled nanotube which has cylindrical structurewith a large surface area. The lengths ofHNTs along the longitudinal axis vary from 500 to 2000 nm, and theinner diameter ranges from 15 to 30 nm. Here, we present HNT as a nano-chamber. Selective synthesisof metal-organic frameworks (MOFs) insidelumen of HNT is introduced. This process includes even loading of a precursor for MOFamong HNTs in a solution phase, and following ex-situ solvothermal reaction while the precursoris suspended exclusively inside the lumen of the HNT by capillary action, where the HNTacts as a template as well as an ultra-small vial. This methodensures an even distribution among the tubes and completeisolation of the synthesized material. In this case, synergistic effects between the HNT and the MOF are observed, where the hybrid exhibits unique gas adsorption and growth direction. Enhanced water stability of inner MOF is also observed. We also try to fill the chambers with various organic compounds.
