Summary: In this study, single Fe atoms were successfully immobilized on Fe-SA/CN, which exhibited high efficiency in generating hydrogen peroxide (H2O2) through oxalic acid and O2 activation. Under visible light, the H2O2 concentration generated by Fe-SA/CN reached 40.19 mM g(-1) h(-1), which was 10.44 times higher than that of g-C3N4. This enhancement can be attributed to the formation of metal-organic complexes and rapid electron transfer. Furthermore, the O2 activation capacity of Fe-SA/CN was found to be higher than that of g-C3N4, facilitating H2O2 formation. Density functional theory calculations revealed that O2 was chemically adsorbed on Fe atomic sites, promoting O2 adsorption and activation. The photocatalytic mechanism of SACs-catalyzed H2O2 generation was also elucidated, providing a deeper understanding of this process.

Summary: In this study, a twisty C-TiO2/PCN (CNT) S-scheme heterojunction was fabricated and utilized for the degradation of ciprofloxacin (CIP) through ultrasonic vibration and visible light irradiation. The nitrogen-rich twisty polymeric carbon nitride (PCN) not only induced a non-centrosymmetric structure with enhanced polarity for better piezoelectric effect, but also provided abundant lone pair electrons for promoting n -> pi * transition during photocatalysis. The hybridization with C-TiO2 particles enabled the construction of S-scheme heterojunction in CNT. Under the synergistic effect of ultrasonic vibration and visible light irradiation, the reaction rate constant of CIP degradation by CNT was significantly increased, demonstrating its potential as an efficient and stable approach for environmental remediation.

Summary: In this study, sulfur and sodium co-doped cyano-rich polymeric carbon nitride (NaCNS) was designed to enhance the photocatalytic degradation of atrazine (ATZ) with peroxymonosulfate (PMS) assistance. NaCNS was synthesized through a two-step thermal condensation method with the presence of sodium chloride and cysteine. Batch experiments showed that the reaction rate constant of NaCNS was significantly increased by nearly sixfold compared to pristine carbon nitride. The enhanced photocatalytic performance was attributed to the dual modulation of NaCNS, with sodium acting as a PMS activation site and the cyano and sulfur forming an electronic push-pull system for improved photocarrier separation.

Summary: Metal components have significant impacts on the generation of persistent free radicals (PFRs) in biochar. This study investigates the effect of interactions among metal components on the formation of PFRs during biomass pyrolysis. The results show that the coupling of Fe with Co and Ni increases the abundance of PFRs in iron-containing biochars (IBCs), while Zn inhibits PFRs generation. Persulfate activation experiments confirm that PFRs are critical redox sites. NiFeO/BC is identified as a more efficient catalyst for PFRs activation. This study provides new methods for regulating PFRs in biochar and advances the understanding of metal-containing biomass pyrolysis processes.
