Direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 on a Pd-based catalyst has emerged as a promising route to replace the energy-consuming, highly inefficient anthraquinone process. However, Pd is also a good catalyst for the decomposition of H2O2, thereby compromising the selectivity toward the desired product. The coupling between the formation and decomposition reactions makes it difficult to single out the most important parameter that controls the selectivity toward direct synthesis of H2O2. Herein, support-free monometallic Pd nanocrystals with different shapes and surface strains are used to investigate their impacts on the decomposition kinetics of H2O2. The kinetics are analyzed by tracking the concentration of the remaining H2O2 using IR spectroscopy. The data indicates that both surface structure and strain affect the decomposition kinetics of H2O2, but their impacts are inferior to that caused by Br-, a surface capping agent for the Pd{100} facets. The exptl. results are consistent with the trend obtained through d. functional theory calculations This work helps shed light on the development of Pd-based catalysts for the direct synthesis of H2O2 by offering strategies to mitigate the decomposition of the desired product. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Related Products of 13820-53-6).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Related Products of 13820-53-6
