Functional partition of Fe and Ti co-doped g-C3N4 for photo-Fenton degradation of oxytetracycline: Performance, mechanism, and DFT study

Cui Lai et al.

Summary: In this study, Fe and Ti co-doped graphitic carbon nitride (FTCN) with high catalytic ability was synthesized using a two-step calcination method. The photoelectrochemical results showed that FTCN had a reduced bandgap and promoted photocarrier transfer efficiency, leading to excellent performance in oxytetracycline (OTC) degradation (90% within 10 min). The main reactive oxygen species and intermediates of OTC in the photo-Fenton process were identified. Combining experimental data and density functional theory (DFT) provided a deep understanding of the mechanism. Interestingly, Fe and Ti were found to act as the main activation centers for H2O2 and O2, respectively, while few oxygen-containing metal active sites were involved in the activation process. The synergistic effect of bimetallic doping played a significant role in enhancing the photoFenton catalytic performance. Hopefully, this study can contribute to the development of new approaches for designing highly efficient multifunctional catalysts or dual single-atom catalysts.

Ultrahigh Performance H2O2 Generation by Single-Atom Fe Catalysts with N/O Bidentate Ligand via Oxalic Acid and Oxygen Molecules Activation

Mingming Zhang et al.

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: By breaking the structural symmetry of the single atomic active site, the photocatalytic water oxidation pathway can be tuned for selective oxidation of CH4 to CH3OH in aqueous solution. The water oxidation ability and its influence on photocatalytic oxidation of CH4 over symmetrically coordinated cobalt single atom (Co-4N) and asymmetrically coordinated cobalt single atom (Co-C2N2) photocatalysts on carbon nitride were systematically investigated. It was found that the AC-Co1/PCNKOH photocatalyst exhibited a super selectivity of 87.22% for CH4 oxidation to CH3OH, while the SC-Co1/PCN catalyst only achieved 45%. Furthermore, AC-Co1/PCNKOH showed a CH4 conversion of 2.42% and a CH3OH yield of 2.11%. In-depth analysis revealed that AC-Co1/PCNKOH possessed the desired electronic configuration for single-electron transfer water oxidation reaction during photocatalysis, leading to significantly enhanced selectivity for CH4 oxidation to CH3OH under illumination.

Carbon Nitride Photocatalysts with Integrated Oxidation and Reduction Atomic Active Centers for Improved CO2 Conversion

Honghui Ou et al.

Summary: Single-atom active-site catalysts have attracted significant attention in the field of photocatalytic CO2 conversion. However, designing active sites for CO2 reduction and H2O oxidation simultaneously on a photocatalyst and combining the corresponding half-reaction in a photocatalytic system is still difficult. In this study, a bimetallic single-atom active-site photocatalyst with two compatible active centers of Mn and Co was synthesized. The active center of Mn promotes H2O oxidation by accumulating photogenerated holes, while the active center of Co enhances CO2 activation by modifying the bond length and bond angle of CO2 molecules. The synthesized Mn1Co1/CN catalyst exhibited a significantly higher CO production rate compared to the corresponding single-metal active-site photocatalyst due to the synergistic effect of the atomic active centers.

Effect of Carbon Doping on CO2-Reduction Activity of Single Cobalt Sites in Graphitic Carbon Nitride

Peipei Huang et al.

Summary: Single-atom catalysts, specifically single Co2+ sites on carbon-doped graphitic carbon nitride, show enhanced activity in visible-light CO2 reduction. The carbon doping improves the photoresponse of C3N4 in the visible region and enhances charge separation, leading to enhanced photocatalytic activity. However, high levels of carbon doping can have a detrimental effect on the photocatalytic activity by altering the structure of C3N4 and generating defect sites responsible for charge recombination.
