Dehalogenation of chlorinated solvents using a palladium catalyst and hydrogen gasLowry, GReinhard, MMcNab, W
Palladium used as a catalytic component is generally supported in an amount of from about 0.01 to about 10.0 wt%, preferably from about 0.05 to about 5.0 wt%, more preferably from about 0.1 to about 2.0 wt%, based on the total weight of catalyst. If palladium is supported in an amount ...

Palladium catalyzed-dehalogenation of aryl chlorides and bromides using phosphite ligands The catalytic system based on Pd–phosphite for the dehalogenation reactions of aryl chlorides and bromides is described. The Pd–phosphite catalyst effect... Jeongju,Moon,and,... - 《Journal of Organometallic ...
Thus, semiconductor TiO2 supported with Pd or Rh nanoparticles has been used as a catalyst with a base such as NaOH. The valence band holes (hVB+), generated by photoexcitation of the catalysts, oxidize alcohols and produce aldehydes (or ketones) and protons (H+). The generated H+ is ...

The supported Pd particles were used as an efficient heterogeneous catalyst for the hydrodehalogenation of halogenated organics under hydrogen transfer condition using hydrazine hydrate as hydrogen donating agent. The effect of various reaction parameters such as temperature, time, and nature of support, ...
1. Synthesis of metal complexes: A metal complex, such as a palladium complex or a platinum complex, is synthesized as an active center of the catalyst. 2. Supported catalyst: The metal catalyst is supported on a porous material to improve the stability and reaction effect of the catalyst. ...
The suspension containing 0.5 g L−1 catalyst was purged with H2 (purity = 99.9995%) for 5 min prior to the reaction, followed by addition of aqueous stock (5 mM) of 4-CP (Sigma, 99%), 2,4-D (Sigma, 99%), or TCP (Sigma, 98%) using a syringe to initiate ...
As is seen in Fig. 1A, 4-CP and 4-BP can be completely hydrodehalogenated using Pd/C catalyst within 40 min and 10 min, respectively. However, the conversion of 4-IP and 4-FP within 90 min are rather low, especially that the conversion of 4-FP is 7.7% within 180 min...
