Pd@NH2-UiO-66(Zr),　with　small-sized　Pd　nanoparticles　encapsulated　inside　the　cavities　of　NH2-UiO-66(Zr),　was　obtained　via　a　double-solvent　impregnation　followed　by　a　photoreduction　process,　which　shows　superior　activity　for　the　visible　light　initiated　syntheses　of　secondary　amines　from　nitro　compounds　and　alcohols,　via　a　sequential　photocatalytic　hydrogenation　of　nitro　compounds/dehydrogenation　of　alcohols,　condensation　of　amines　and　aldehydes　to　imines,　and　the　hydrogenation　of　imines.　Simultaneous　consumption　of　photogenerated　electrons/holes　in　the　photocatalytic　hydrogenation　of　nitro　compounds　to　amines　and　dehydrogenation　of　alcohols　to　aldehydes　promotes　the　whole　reaction.　Due　to　the　confinement　effect　of　the　cavity　and　the　small-sized　Pd　nanoparticles,　Pd@NH2-UiO-66(Zr)　shows　significantly　superior　performance　as　compared　with　Pd/NH2-UiO-66　(Zr),　in　which　larger　Pd　nanoparticles　are　deposited　on　the　surface.　This　study　provides　an　efficient　and　green　strategy　for　the　production　of　secondary　amines　and　highlights　the　great　potential　of　using　M/MOFs　nano-composites　as　multifunctional　catalysts　for　light　induced　one-pot　tandem　reactions.
