“…This phenomenon is most often responsible for Pd/C deactivation in liquid-phase reactions. 60 Adsorption of organic compounds on the Pd surface or partial oxidation of Pd nanoparticles as possible reasons for the deactivation can be excluded due to the rigorous posttreatment. In contrast, the 0.1Sn-Pd/C catalyst shows a considerable stability during five cycles under the optimized conditions (Figure S5).…”

“…This insignificant deactivation is probably due to the partial leaching of Pd, as ICP-MS reveals that 5.9% of the Pd species has leached into the reaction mixture. This phenomenon is most often responsible for Pd/C deactivation in liquid-phase reactions . Adsorption of organic compounds on the Pd surface or partial oxidation of Pd nanoparticles as possible reasons for the deactivation can be excluded due to the rigorous post-treatment.…”

“…In 2018, a Pd/C catalyst was synthesized by selective adsorption deposition, in which a cationic palladium precursor such as [Pd(NH 3 ) 4 ] 2+ was selectively adsorbed on a negatively charged activated carbon surface and subsequently slowly converted to palladium hydroxide with urea [191]. The formation of ultra-small and monodispersed Pd nanoparticles with a high Pd 2+ /Pd 0 ratio resulted in high initial H 2 O 2 productivity (8606 mmol H 2 O 2 /g Pd h) and selectivity (95.1%).…”

“…As an effective and eco-friendly oxidant, hydrogen peroxide (H 2 O 2 ) has attracted worldwide attention in various industrial fields. The active oxygen content per H 2 O 2 molecule is as high as 47%, with only water forming as a byproduct after the oxidation reaction. In addition, with the exception of H 2 O 2 , most oxidants, including halogen-based gases (F 2 , Cl 2 , Br 2 , and I 2 ), NaClO-, HNO 3 -, SO 2 -, and Cr-based hexavalent chromium (CrO 3 ), manganite (MnO 4 2– ), and metal tetroxide (RuO 4 , and OsO 4 ), inevitably generate harmful byproducts (e.g., halide ions, NO x , sulfur, and metal ions).…”
