There exists great potential in combining heterogeneous metallic nanoparticle active sites and enzymic active sites for sequentially catalyzed chem. transformations. This study provides an illustrative system where glucose oxidase and gold nanoparticles are successfully combined into a hybrid catalytic material. This multi-site catalyst is used to convert glucose to a more valuable saccharic acid product without the need for a strong oxidant such as H2O2, hypochlorite, or nitric acid to be externally added. We synthesize a hybrid material that is able to oxidize glucose to gluconic acid and H2O2 with glucose oxidase, and gold catalyzes the further oxidation to saccharic acid. The in situ generation of H2O2 provides a proximal, dilute oxidizing agent for further oxidation It is observed that higher pH promotes H2O2 decomposition and saccharic acid generation catalyzed by the gold nanoparticles. A 33% yield of saccharic acid in 90 min is observed without the addition of nitric acid, harsh oxidant, above ambient temperatures, or high oxygen pressures. The results demonstrate a cooperative reaction cascade system that opens new possibilities for metal nanoparticle-enzyme hybrid materials that can be applied to catalytic biomass conversion in mild reaction conditions.
