“…Researchers have carried out a wide range of scientific and technical approaches to achieve the full application of clean energy [ 2 ]. Catalytic oxidation technology is widely used due to its high efficiency, low operating temperature and lack of secondary pollution [ 3 ]. In recent years, precious metal catalysts loaded on activated carbon or “reducible” carriers have been very effective redox catalysts due to their high activity and excellent low-temperature catalytic properties.…”

In this study, the typical oxidation process of Au/C catalysts exposed to HCl is presented. Although the process violates the standard electrode potentials, the “oxidized” tendency of Au(0) species is analyzed. This oxidation behavior can only be triggered over the Au/C sample within residual cationic Au species, and terminated over the completely metallic Au(0)/C sample. This study demonstrates that the presence of surface chlorination species cannot facilitate the oxidation of Au(0) and Au(I) when the sample is treated with HCl alone, which excludes the oxidation paths of: Au(0) → Au(III) and Au(I) → Au(III). The reported “HCl-oxidized Au(0)” behavior is partially caused by the migration of Au(III) species in the carbon bulk-phase, which occurs outside the XPS detection limit region and into the detection limit rather than the “HCl-oxidized Au(0)” itself. The mechanism of driving the bulk-phase Au(III) migrated from the steady destabilized state to the carbon surface is then studied. This study demonstrates that the migration of Au cannot be neglected behind the curious oxidation phenomenon by HCl, which provides a new perspective for the oxidation of other noble metals by HCl.

“…Among them, Fe-based MOFs are made up of metal ions (Al 3+ , Fe 3+ , and Cr 3+ ) with terephthalic acid through strong coordination bonds. 22,29 MOF materials have unique performance advantages, such as controllable pore size and modified pore surface, low density, high surface area, possibility to be functionalized and environmental stability, and thus this new type of porous material has been widely used in many fields, for example, adsorption, 30 photocatalysis, 31,32 catalysis, 33,34 drug delivery, gas storage and purification 35 and sensing. 36,37 The organic ligands of MOFs are good antennas for light adsorption for the production of photocarriers via LMCT pathways and their iron clusters act as abundant active sites, 38 and thus they are appealing for application in photocatalysis.…”

“…These free radicals attacked the OPEs’ structure for the purpose of degradation [ 28 ]. Metal-organic frameworks (MOFs) were a new material with a nanometer network, which were the most promising photocatalysts at present and commonly used catalysts for OPEs under visible light conditions [ 29 , 30 , 31 ]. Such as MIL-101 (Fe), MIL-88A, and MIL-88B-NH 2 .…”

Organophosphate Esters (OPEs) Flame Retardants in Water: A Review of Photocatalysis, Adsorption, and Biological Degradation

et al. 2023

As a substitute for banned brominated flame retardants (BFRs), the use of organophosphate esters (OPEs) increased year by year with the increase in industrial production and living demand. It was inevitable that OPEs would be discharged into wastewater in excess, which posed a great threat to the health of human beings and aquatic organisms. In the past few decades, people used various methods to remove refractory OPEs. This paper reviewed the photocatalysis method, the adsorption method with wide applicability, and the biological method mainly relying on enzymolysis and hydrolysis to degrade OPEs in water. All three of these methods had the advantages of high removal efficiency and environmental protection for various organic pollutants. The degradation efficiency of OPEs, degradation mechanisms, and conversion products of OPEs by three methods were discussed and summarized. Finally, the development prospects and challenges of OPEs’ degradation technology were discussed.
