Interest and challenges remain in designing synthesizing catalysts with nature-like complexity at few-nm scale to harness unprecedented functionalities by using sustainable solar light. We introduce "nanocatalosomes"-a bio-inspired bilayer-vesicular design of nanoreactor metallic bilayer shell-in-shell structure, having numerous controllable confined cavities within interlayer space, customizable different noble metals. The intershell-confined plasmonically coupled hot-nanospaces the play a pivotal role harnessing catalytic effects for various organic transformations, as demonstrated "acceptorless dehydrogenation", "Suzuki-Miyaura cross-coupling" "alkynyl annulation" affording clean conversions turnover frequencies (TOFs) least one order magnitude higher than state-of-the-art Au-nanorod-based plasmonic catalysts. This work paves way towards next-generation nanoreactors chemical transformations energy.
