Experimental and Modelling Study of the Effect of Water on the Purification Performance of Pd-Based Three-way Catalysts

Nihon Kikai Gakkai ronbunshu, 2022
To develop a high-performance three-way catalyst, it is necessary to construct an accurate catalytic reaction model. Previously, we have developed the three-way catalyst model under dry simulated exhaust gas conditions.

Attaching palladium catalysts to antibodies

Bioorganic & Medicinal Chemistry, 2021
Antibody-directed enzyme prodrug therapy (ADEPT) is a powerful concept in which antibody targeting is linked to enzymatic prodrug activation. The work herein describes the first steps in the development of a technology analogous to ADEPT but in which a palladium catalyst is attached of an antibody rather than an enzyme.

Facile synthesis of palladium nanoparticles supported on urea-based porous organic polymers and its catalytic properties in Suzuki-Miyaura coupling

Journal of Saudi Chemical Society, 2020
By using urea linked porous organic polymers as template, a new nano palladium catalyst with low Pd loading can be easily prepared (1.0 wt% Pd only). Although such less amount of Pd was contained in this new catalyst, it is still an effective catalyst ...
