  1. Photocatalytic Conversion of Cellulosic Biomass into Gaseous Fuels Frank E. Osterloh, Department of Chemistry, University of California, Davis, CA 95616 VO2 Nanoribbons are a Photocatalyst for Conversion of Glucose into Hydrogen Fuel. At 440 nm, the Quantum Efficiency of the Process is 1.00-1.69 %.
