Hydrogen Peroxide

A computational study on the reduction of O2 to H2O2 using small polycyclic aromatic molecules

“…However, in this description the starting catalyst has additional hydrogenation at the 9, and 10 position on the ring. In a more recent description of the industrial process 29 it is reported that additional hydrogenation tends to occur at the 5, 6, 7, and 8 position to a much greater degree and results in a less active catalyst than if the anthracene moiety was unsaturated. Given that the calculations included in this work more closely resemble the more recent description of the industrial process, we will conclude that the process involves only one AHQ molecule.…”

“…The efficiency of this photochemical process can be significantly improved with the addition of Cu 2+ 28 . However, the most common way to synthesize H 2 O 2 is via the AQ process 29 , which is illustrated in Figure 1. In industry, the majority of H 2 O 2 is produced using the AQ process.…”

“…In industry, the majority of H 2 O 2 is produced using the AQ process. It consists of two processes: the hydrogenation process and the autoxidation process 29 . H 2 O 2 is synthesized in the autoxidation step and the catalyst is regenerated with H 2 on a Pd catalyst to form anthrahydroquinone (AHQ).…”

Immobilization of molecular catalysts for artificial photosynthesis

“…Anthraquinone and its derivatives and its derivatives have been explored as molecular electrocatalysts for O 2 reduction, since anthraquinone is low-cost, has suitable chemical functionality, and high selectivity for H 2 O 2 [136][137][138][139]. Attempts to immobilize anthraquinones on electrodes comprise: (i) directly linking to glassy carbon electrodes through covalent bonds [140], (ii) incorporating in insoluble polymer matrix [141], (iii) and covalently linking to CNTs [142].…”
