Summary: One of the challenges in multicomponent metal-organic frameworks (MOFs) is to achieve selective product formation by finely tuning their active centers. In this study, a technique called cluster labilization was used to create hierarchically porous MOF composites with hollow structures and adjustable active centers. By partially replacing zirconium with cerium in the hexanuclear clusters of UiO-66, unevenly distributed yolk-shell structures (YSS) were formed, which can be further transformed into single-shell hollow structures (SSHS) or double-shell hollow structures (DSHS) through acid treatment or annealing. These structures exhibit tunable catalytic activity, reversed selectivity, and high stability in tandem reactions and photoreactions.

Summary: This study comprehensively analyzed the molecular transformation behavior of dissolved organic matters (DOM) during peroxymonosulfate (PMS) activation by biochar for organic degradation. Different types of reactions were observed, including oxidative decarbonization, dehydrogenation, dehydration, deheteroatomisation, hydration, and N/S oxidation reactions. Certain compounds present in DOM showed moderate or strong inhibition effects on contaminant degradation. This information can be used to regulate ROS composition and DOM conversion process in PMS systems and minimize the interference of DOM conversion intermediates on PMS activation and degradation of target pollutants.

Summary: The relationship between the single-atom structure and catalytic activity in Fenton-like catalysis was investigated. Different molecular structures and a light-dependent mechanism were discovered. The Co-N1+3 configuration favored the formation and had higher catalytic activity, while the Co-N2+2 configuration had inferior catalytic activity and negative effects on the adjacent Co-N1+3 site. Additionally, a 100% nonradical reaction pathway that could be photo-switched to a nonradical/radical process by visible light was revealed. This work enriches the fundamentals of single-atom catalysis and provides new insights into the atomic metal structure, reaction pathways and mechanisms, and structure-activity relationships in organic degradation.
