Squalane is an important ingredient in the cosmetic, nutraceutical, and pharmaceutical industries. It has also been used as a model compound for the hydrocracking of crude and microalgae oil. Thus, a series of green heterogeneous metal catalysts were prepared to achieve complete hydrogenation of highly unsaturated squalene into squalane. Surface modification of the clay and metal intercalation simultaneously occurred during wet impregnation. The Pd‐nanoparticles‐intercalated clay with a dominating Pd(1 1 1) facet showed the highest reactivity and selectivity. The catalyst was stable with very low Pd leaching (≈0.03 ppm) and was recyclable without losing any significant catalytic activity.
