An Efficient Approach for the Synthesis of Pd Nanoparticles via Modifying Al2O3 with Cellulose and Its Application for CO Oxidation

Pd nanoparticles were generated over Al2O3 modified by cellulose allowing a facile crystallization and used for CO oxidation. Smaller particles were prone to be formed over the support with the assistance of cellulose. The enhanced catalytic activity could be ascribed to the positive interaction between Pd particles and the modulated support. Palladium Nanocatalyst: A new approach for Al2O3 modification with cellulose was proposed and then designed for the preparation of Pd/Al2O3 nanocatalysts by impregnation and in situ reduction. The modification of cellulose on Al2O3 contributed to the formation of small Pd particles and therefore improved the activity of the resulting catalyst for CO oxidation.
