Abstract Degradation of organic contaminants into less toxic substances is the best option to remove these compounds rather than using conventional techniques. The sulfate radical-based-advanced oxidation process an effective strategy that degrades by activating peroxymonosulfate (PMS). Such a generates singlet oxygen ( 1 O 2 ), hydroxyl $$^ \bullet \!{{{\mathrm{OH}}}}$$ ∙OH and $${{{\mathrm{SO}}}}_4^{ \bullet\! - }$$ xmlns:mml="http://www.w3.org/1998/Math/MathML">SO4∙− ) radicals. \!- distinguished its high selectivity activity toward degradation contaminates compared other Various catalysts are employed in PMS activation including layered doubled hydroxides (LDHs), which characterized their facile synthesis catalytic activity. This review article first attempt compile recent progress common pollutants aromatic compounds, pharmaceutical residues, dyes via LDH-based catalysts. pathways, reaction parameters’ influence, stability LDHs, comparisons between different investigated this work.

Directional and Ultrafast Charge Transfer in Oxygen‐Vacancy‐Rich ZnO@Single‐Atom Cobalt Core‐Shell Junction for Photo‐Fenton‐Like Reaction

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(30)

Опубликована: Май 31, 2023

In photosynthesis, solar energy is harvested by photosensitizers, and then, the excited electrons transfer via a Z-Scheme mode to enzymatic catalytic centers trigger redox reactions. Herein, we constructed core-shell Z-scheme heterojunction of semiconductor@single-atom catalysts (SACs). The oxygen-vacancy-rich ZnO core single-atom Co-N4 sites supported on nitrogen-rich carbon shell (SA-Co-CN) act as photosensitizer enzyme-mimicking active centers, respectively. Driven built-in electric field across heterojunction, photoexcited could rapidly (2 ps) from n-type p-type SA-Co-CN shell, finally boosting performance surface-exposed for peroxymonosulfate (PMS) activation under light irradiation. synergies between photocatalysis heterogeneous Fenton-like reaction lead phenomenally enhanced production various reactive oxygen species rapid degradation microcontaminants in water. Experimental theoretical results validate that interfacial coupling with greatly facilitates PMS adsorption reducing enhancing cascade electron processes photo-Fenton-like reaction.
