Structure sensitivity in catalytic hydrogenation of glucose over ruthenium
•Selective hydrogenation of glucose.•Carbon nanotubes as support.•Reaction is structure sensitive.•Rate maximum at Ru cluster size 3 nm.
The structure sensitivity was studied in the hydrogenation of glucose to sorbitol over supported ruthenium catalysts in a semi-batch reactor. Ruthenium on carbon supports with different ruthenium particle sizes was prepared and evaluated in the hydrogenation experiments. The highest turnover frequency was obtained with a catalyst bearing average ruthenium particle size of ca. 3 nm.
