A novel Cu-based catalyst supported in chitosan nanoparticles for the hydrogenation of carbon dioxide to methanol

Chitosan nanoparticles were used as a support for the Cu-based catalyst to convert carbon dioxide to methanol under mild conditions. A statistically significant model for space-time yield (STY) and selectivity as a function of synthesis-related parameters was achieved, predicting optimal values of p...
