An easy and efficient method, water-assisted chemical vapor deposition (CVD), was developed to modify multi-walled carbon nanotubes (CNTs) during the CNT growth process. The as-synthesized CNTs with (-H2O) and without (-p) water assistance were explored as ruthenium (Ru) catalyst support for conversion of cellobiose. The Ru/CNTs-H2O catalyst shows much higher conversion of cellobiose (73.6%) and yield of sugar alcohols (39%) than those of Ru/CNTs-p catalyst (28.9% and 21.3%, respectively), which could be ascribed to the highly dispersed Ru nanoparticles due to the presence of oxygen-containing groups and uniform defects on the tube-walls introduced in the water-assisted CVD process.
