Kinetic study of the catalytic decomposition of H 2 O 2 in phosphoric acid medium

Rapid Hydrogen Peroxide Decomposition Using a Microreactor

“…As a result, to understand the decomposition behavior under acidic working conditions becomes necessary. In addition, it has been shown that the presence of halides also suppresses the destruction of H 2 O 2 . Consequently, in this work the inhibition effect of halides and protonic acids was studied.…”

“…The line did not go through the origin, indicating that this model might not apply when X is high. The k ‐value has been reported to be 1.3 × 10 −4 s −1 in other researches , . The difference could be attributed to the thorough mass transfer in microreactors, the others catalysts used, and the different reaction conditions including temperature, solvent, and presence of impurities.…”

“…The mechanism of H 2 O 2 decomposition has been studied before by Choudhary et al , Zeineb et al , Ribeiro et al , Gudarzi et al , and Hessel et al . The effect of medium composition , and structure and surface chemistry of the catalysts , , have been investigated systematically. However, most of the kinetic studies have been performed in batch reactors, where the influence of mass transfer is difficult to exclude.…”

Polymeric Schiff Base Metal Complexes Based on Thermo‐Responsive PNIPAM: Synthesis, Characterization and Catalytic Activity

“…The most employed conventional catalytic systems for H 2 O 2 decomposition are metal oxides and supported or doped ones, mixed oxides, perovskite catalysts and transition metal ions or their supported forms . Some other recent catalysts are transition metal doped anatase /TiO 2 , PVP‐protected Rh/Au bimetallic nanoparticles (BNPs), nano‐crystalline Co 3 O 4 , Ca‐doped BiFeO 3 , hematite (Fe), Fe–Ti or Fe–Al, phosphoric acid media containing ferrous ion and Schwertmannite (Sch)‐immobilized Mo…”

“…The most employed conventional catalytic systems for H 2 O 2 decomposition are metal oxides [16] and supported or doped ones, [17] mixed oxides, [18] perovskite catalysts [19] and transition metal ions [20] or their supported forms. [21] Some other recent catalysts are transition metal doped anatase/TiO 2 , [22] PVP-protected Rh/Au bimetallic nanoparticles (BNPs), [23] nano-crystalline Co 3 O 4 , [24] Ca-doped BiFeO 3 , [25] hematite (Fe), Fe-Ti or Fe-Al, [26] phosphoric acid media containing ferrous ion [27] and Schwertmannite (Sch)immobilized Mo. [28] In consequence of our precedent report on the synthesis of cross-linked polyacrylamide resin anchored Schiff base-metal complexes for hydrogen peroxide decomposition, [29] we introduce novel smart catalytic system of Schiff base metal complexes based on thermo-responsive PNIPAM and explored their catalytic function in the H 2 O 2 decomposition.…”
