Achieving efficient toluene mineralization over ordered porous LaMnO3 catalyst: The synergistic effect of high valence manganese and surface lattice oxygen

Insight into electrocatalytic activation of peroxymonosulfate by Ti/MnO2 anode via one-step electrodeposition approach toward degradation of levofloxacin

“…The Mn 2p spectrum shows the valence state transition of Mn 4+ /Mn 3+ , which indicates that the chemical activity of the Mn electron pair is crucial for the formation of SO 4 ˙ − by PMS (eqn (1) and (2)). 55–57 PMS oxidizes Mn 3+ to Mn 4+ , and Mn 4+ is reduced to Mn 3+ by free radicals produced by PMS. With an increase in current, eqn (3) occurs preferentially, and the production of SO 5 ˙ − is maintained at a high level, which eventually leads to the efficient removal of LFX (eqn (4)–(8)).…”

Cooperative and Bifunctional Adsorbent‐Catalyst Materials for In‐situ VOCs Capture‐Conversion

“…explains the role of high valence manganese and surface lattice oxygen in the performance of LaMnO 3 towards the combustion of toluene. Figure 6 briefly explain the catalytic mechanism involved in the oxidation of toluene on the surface of LaMnO 3 [123] …”

“…Figure 6 briefly explain the catalytic mechanism involved in the oxidation of toluene on the surface of LaMnO 3 . [123] Layered manganese oxide was prepared via the reaction of KMnO 4 and Ammonium oxalate to study the effect of water in the adsorption of formaldehyde. This experiment was conducted at different temperatures and Wang et al [124] reported three classes of water (adsorbed H 2 O, interlayer H 2 O and hydroxyl) on the adsorbent which has helped the adsorption of formaldehyde, and it was established that the higher the water content the better the activity it has.…”

Removal of Formaldehyde and Its Analogues Using a Hybrid Assembly of Pyrene-Modified Hydrazide and rGO: A Negative Carbon Emission and Green Chemical Decomposition Method

“…Using plant’s absorption and physical absorption methods to remove formaldehyde is slow, non-specific, and less efficient. ,,, Catalytic oxidization is one of the chemical methods for formaldehyde decomposition. However, the complete decomposition of formaldehyde by catalytic oxidization creates ozone and other harmful chemicals. , Recently, it has been reported that the mineralization of volatile organic compounds can be achieved by increasing the catalytic activity of photothermal catalysts through surface lattice oxygen activation. , However, this method is mostly used for the removal of toluene and no application has been found for formaldehyde removal yet …”
