The activation characteristics of the decomposition of H2O2 on palladium-carbon catalysts

Large scale electrochemical synthesis of high quality carbon nanodots and their photocatalytic property

“…The catalytic properties of the C-dots could be explained by the formation of an activated transition complex [C⋯H 2 O 2 ], which can transfer electron density from the π-system of the C-dots to the peroxide molecule during the decomposition process of H 2 O 2 . 16 Particularly, a better catalytic activity of the C-dots was achieved when this reaction system was exposed to visible light. As shown in Fig.…”

One-step ultrasonic synthesis of fluorescent N-doped carbon dots from glucose and their visible-light sensitive photocatalytic ability

“…18,35 In the photocatalytic process, an activated transition complex [CÁ Á Á 2 O 2 ] was formed and transferred electrons from the p-system of the NCDs to the peroxide molecule during the process of H 2 O 2 decomposition, then the active species (OH ) with strong oxidation capability were generated, subsequently causing the degradation of MO. 36 In summary, we have developed a facile and one-pot ultrasonic synthesis of NCDs by using glucose and aqua ammonia as precursors. The NCDs possess excellent aqueous dispersibility without any surface modifications, and significantly, they exhibit stable and strong visible emission and excellent up-conversion PL.…”

Benzoyl peroxide decomposition on the surface of carbon materials on the base of activated carbon KAU

“…During carbon oxidation, as shown in Table 2, mainly carboxylic and phenolic groups are formed on its surface, which can make quite stable H-complexes with peroxide molecule (for the H2O2 molecule it was proved in papers [9,11]) and thus exclude the participation of carbon in the decomposition reaction. So, with high probability we can say that the catalytic activity of BP decomposition by oxygen-containing CM depends on both the formation of reactive complexes «CM...PB», where destruction of PB molecules and inhibition of the BP degradation process occur by the formation of H-complex «Oxidized CM…BP».…”

“…Quantum chemical simulation of the catalytic activity of CM made it clear [9][10][11][12] that the reaction of hydrogen peroxide decomposition over surface of a carbon nanocluster (CNC) functionalized with heteroatoms O and N occurred due to the transfer of electron density from the cluster to the hydrogen peroxide molecule in the formed complexes «CNC-H2O2». In such systems the rate of decay is controlled by the ionization potential (electron work function or energy value of the highest occupied molecular orbital) of carbon cluster.…”
