Outline of Final Research Achievements

Polyoxometalates were immobilized on carbon support and used as a strong solid acid catalyst for efficient biomass conversion under microwaves. Hydrolysis of cellobiose was conducted as a model reaction of biomass hydrolysis to evaluate the effects of microwave susceptibility of the catalysts on their activity. The carbon-supported polyoxometalates exhibited higher activitiy on cellobiose hydrolysis under microwaves than convetional heating. The carbon-supported polyoxometalates were also effective for hydrolysis of real biomass such as green seaweed (Monostroma latissimum). The generation of local hot spot at the vicinity of the catalyst surface might have contributed to improve hydrolytic activity of the catalyst.
