Solar　energy-induced　cascade/tandem　reactions　in　one-pot　are　sustainable　and　green.　Herein,　the　Pd/NiTi-LDH　nanocomposite,　with　Pd　nanoparticles　(NPs)　(∼3-6　nm)　deposited　on　NiTi-LDH　nanosheets,　was　obtained　and　was　applied　in　the　reaction　between　nitro　aromatics　and　alcohols　to　synthesize　secondary　amines　under　visible　light.　The　superior　performance　observed　over　the　as-obtained　Pd/NiTi-LDH　nanocomposite　for　this　reaction　can　be　attributed　to　a　successful　merging　of　Pd-based　hydrogenation　and　LDH-based　photocatalysis,　in　which　consecutive　light-induced　hydrogenation　of　nitro　compounds　to　amines,　dehydrogenation　of　alcohols　to　aldehydes,　condensation　between　the　in　situ　formed　aldehydes　and　amines　to　imines　and　the　hydrogenation　of　final　imines　to　generate　the　desired　secondary　amines　were　realized　in　one　pot　over　Pd/NiTi-LDH　under　visible　light.　This　work　shows　an　effective　and　green　strategy　in　the　synthesis　of　secondary　amines.　This　study　also　demonstrates　the　high　potential　of　using　metal/LDH　nanocomposites　for　light-initiated　organic　syntheses.　©　2023　The　Royal　Society　of　Chemistry.
