The purpose of this study is to prepare catalysts with multicomponent metal nanoparticles (NPs) on liposome membranes, where a liposome is a closed-phospholipid bilayer membrane. For examples, Pt NPs supported liposomes made of 1,2-dipalmitoyl phosphatidylcholine (DPPC) was denoted PtNP@DPPC. A selective oxidation of 5-hydroxymethylfurfural (HMF) as a model case was examined to optimize a composition of metal species suitable for HMF oxidation. PtBiAuNPs@DPPC achieved high selectivity to 2,5-diformyl furfural, while metal NPs@DPPC with four and five metal species did not achieve higher selectivity. An inhibitory effect by Ru and the promotion of reaction to byproducts other than expected products are considered as possible reasons. Thus, a tuning of metal species would improve the reactivity / selectivity of HMF oxidation reaction.
