The paper comparatively assesses the physicochemical properties of natural aluminosilicate nanotubes (halloysite) provided by domestic (HNT-Ch) vs. foreign (HNT-A) manufacturers, as well as the catalytic activity of ruthenium catalysts synthesized therefrom. The composition, structure, and textural properties of the materials were measured by a combination of physicochemical methods, such as TEM, ED–XRF, low-temperature nitrogen adsorption/desorption, and H2–TPR. The activity of the synthetic catalysts was examined in benzene hydrogenation at 80°C and a hydrogen pressure of 3 MPa in both a hydrocarbon and aqueous–hydrocarbon system. The catalysts supported on HNT-Ch and HNT-A were found to have similar physicochemical properties and to exhibit high activity in benzene hydrogenation, both in the monophasic and biphasic systems, thus ensuring quantitative substrate conversion with 100% cyclohexane selectivity.
