Investigation on the oxidation process of SiCO glasses

Ion beam analysis was applied for the first time to characterize the oxidation process of silicon oxycarbides (SiCO) glasses (belonging to the class of polymer-derived ceramics). The technique unveiled the structure of the interface between the silica scale and the SiCO substrate. At the early oxidation stage, a smooth concentration profile was observed between the surface silica layer and the

Advancing photoreforming of organics: highlights on

Photoreforming is a process that harnesses the redox ability of photocatalysts upon illumination, to simultaneously drive the reduction of H + into hydrogen gas and oxidation of organic compounds. Over the past few decades, significant effort has been devoted to improving the photocatalytic hydrogen evolution efficiency, while substantially less focus has been directed towards the oxidation

ABTS as an Electron Shuttle to Enhance the Oxidation

In this study, it was, interestingly, found that 2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulfonate (ABTS), a widely used electron shuttle, could greatly accelerate the oxidation of substituted phenols by potassium permanganate (Mn(VII)) in aqueous solutions at pH 5–9. This was attributed to the fact that these substituted phenols could be readily oxidized by the stable radical cation

Coordinatively unsaturated (CUS) iron sites are highly active in catalytic oxidation reactions; however, maintaining the CUS structure of iron during heterogeneous catalytic reactions is a great challenge. Here, we report a strategy to stabilize single-atom CUS iron sites by embedding highly dispersed FeN4 centers in the graphene matrix. The atomic structure of FeN4 centers in graphene was

Plasmonic photocatalysis via hot charge carriers suffers from their short lifetime compared with the sluggish kinetics of most reactions. To increase lifetime, adsorbates on the surface of a plasmonic metal may create preferential states for electrons to be excited from.
