A novel amorphous Ni catalyst supported on alumina has been developed for the production of hydrogen peroxide from carbon monoxide, water, and oxygen. The experimental investigation confirmed that the promoter/Ni loading ratio and the preparation conditions show a significant effect on the activity and catalytic lifetime. Among all the catalysts tested, the Ni-La-B/Al2O3 catalyst with 1:15 molar ratio of La/Ni, dried at 120degreesC. shows the best activity and lifetime for the production of hydrogen peroxide.
