Summary: Electrocatalytic systems are difficult to understand, especially when they involve heterostructured electrodes with multiple interfaces. Current analytical methods are insufficient to handle this complexity, resulting in a lack of understanding of fundamental catalytic aspects. Therefore, it is necessary to address key electrocatalytic and analytical points before proposing new hypotheses.

Summary: In this study, a Si-O doped carbon-based catalyst with biomimetic montmorillonite (MT) structure was prepared for oxidizing refractory organic pollutants via peroxymonosulfate (PMS) activation. The C/Si@MT/PMS system demonstrated ultrafast oxidation of versatile refractory organics and strong resilience against interference from environmental matrixes by enhancing both radicals and electron transfer process (ETP). The ETP oxidation of pollutants in the C/Si@MT/PMS system proceeded through the Si-O site, with kobs data positively correlated to redox parameters such as falling potential and energy gap. The removal of inert aluminosilicate in C/Si@MT retained the lamellar structure, promoting continuous oxidation of pollutants with high stability in a catalytic membrane.

Summary: In this study, a concentrated photothermal catalysis (CPTC) system was developed to convert light into heat effectively. Mn3O4-based catalysts with unsaturated coordination defects were designed for solar-heating photothermal ethyl acetate oxidation without additional energy input. The Mn3O4-3 catalyst exhibited outstanding photothermal catalytic performance under weak simulated sunlight or natural sunlight irradiation. The enriched unsaturated defects in Mn3O4-3 improved the concentration of surface reactive species and regulated the energy-band structure, leading to enhanced light absorption capacity and charge separation. Experimental and theoretical results showed that the abundant Mn defects promoted the dissociation/hydrolysis of ethyl acetate into key intermediates, while the presence of O vacancies facilitated the dissociation of O2 and deep oxidation of intermediates. The reaction pathway of photothermal ethyl acetate oxidation on manganese oxides under sunlight irradiation was revealed. This work provides an attractive CPTC technology for VOCs removal in energy and environmental applications.

Summary: Two-electron water oxidation is attracting more attention as a method for producing H2O2, which can be used in oxygen-deficient environments without the need for oxygen gas bubbling. The design of high-efficiency anode materials is currently the most important research focus. In this study, a general method using Sb2O3 modification is developed to enhance the activity of two-electron water oxidation for H2O2 production. This modification strategy has been demonstrated to improve reaction kinetics, increase specific surface area, and suppress H2O2 decomposition. The Sb-modified electrodes are also capable of efficiently removing difficult-to-degrade organic pollutants and heavy metals.
