Summary: Using semiconductor photocatalysis to convert solar energy into chemical energy is a viable strategy for addressing the energy and environmental crisis. Graphitic carbon nitride (g-C3N4) is a popular 2D photocatalyst with visible light response, low cost, and high stability, but single g-C3N4 photocatalyst has poor performance due to fast recombination of photogenerated electrons and holes. Hybridizing g-C3N4 with other 2D materials to construct 2D/2D heterojunction photocatalysts improves this limitation by offering large contact area and plentiful channels for the migration and separation of photogenerated charge carriers, inheriting the strengths of 2D structure such as high specific surface area and abundant active sites.

Summary: Accelerating charge separation and transfer and increasing visible light absorption are crucial for efficient photocatalytic hydrogen production via water splitting. In this study, we fabricated an in-plane graphited nanocarbon-conjugated polymeric carbon nitride (GNC-C3N4) nanosheet heterostructure photocatalyst for the first time. The incorporation of GNC into the conjugate network of C3N4 significantly enhanced light harvesting and improved charge separation and transfer through the built-in electric field and intimate interface. The optimized GNC-C3N4 photocatalyst exhibited over 15-fold enhancement in photocatalytic hydrogen evolution from water under visible light irradiation compared to C3N4.

Summary: In this work, a graphitic carbon nitride with -C=N defects and S-defects (N-2-SCN-4) was constructed. The H2O2 production efficiency of N-2-SCN-4 under visible light irradiation was found to be 15.4 times higher than that of pristine g-C3N4. The -C=N groups promote H+ adsorption, while the S-defects provide active centers for O-2 adsorption and activation. Surface morphology, microstructure, and photoelectric chemical properties were characterized, and the response range of N-2-SCN-4 to visible light was significantly increased. Charge separation efficiency and selectivity of H2O2 production were also discussed, showing improvement under the synergistic effect of the double defects. This work provides a strategy for enhancing the photocatalytic performance of photocatalysts.

Summary: Metal-organic frameworks (MOFs) have been widely applied in catalysis and sensing due to their large specific surface area, control-lable structure, and high concentration of active metal sites. However, their potential applications in photocatalysis and luminescence sensors face challenges such as charge recombination, low solar energy utilization, low quantum yield, and limited charge transfer. Recent studies have shown that the introduction of carbon dots (CDs) can greatly enhance the functions of MOFs. This paper reviews the synthesis methods of CD-MOF composites and their potential applications in photocatalysis and sensing, with emphasis on representative examples and key features.

Summary: Hindered amine-based electron paramagnetic resonance (EPR) spectroscopy is widely used to detect singlet oxygen (O-1(2)) generated in advanced oxidation processes. However, false detection of O-1(2) can occur due to the interference of reactive species, such as (OH)-O-center dot and high-valence Fe. This study reveals that EPR-based O-1(2) detection can be remarkably misled by common oxidative species and jeopardize the understanding of O-1(2).

Summary: Traditional methods are not efficient in recovering Cu from Cu(II)-EDTA wastewater and result in the formation of secondary contaminants. This study proposes an ozone/percarbonate (O3/SPC) process that can efficiently decomplex Cu(II)-EDTA and recover Cu simultaneously. The results show that the O3/SPC process achieves 100% Cu recovery with a kobs value of 0.103 min-1, compared to 81.2% recovery and a kobs value of 0.042 min-1 for the typical ·OH-based O3/H2O2 process. The O3/SPC process generates the carbonate radical anion (CO3·-) to selectively attack the amino groups of Cu(II)-EDTA, leading to the cleavage of Cu-O and Cu-N bonds.

Summary: MIL-88A(Fe)/BOHP (MxBy) heterojunctions were fabricated as catalysts to activate hydrogen peroxide (H2O2) through visible light illumination. The catalytic degradation efficiency of enrofloxacin (ENR) in the M3B7/Vis/H2O2 system reached almost 100% with good mineralization ability. The formation of interfacial Fe-O-P chemical bonds between MIL-88A(Fe) and BOHP effectively reduced the charge transfer energy barrier and migration distance, leading to efficient separation of photo-generated carriers and improved activation efficiency of H2O2.

Summary: Advanced oxidation processes (AOPs) have diverse applications in treating refractory pollutants, but the investigation of AOP mechanisms at the elementary reaction level is challenging due to the presence of elusive free radicals. Conventional methods have limitations, thus computational chemistry theory, particularly density functional theory (DFT) calculation, provides a promising alternative. This review focuses on the applications of DFT calculations in predicting active sites, exploring reaction selectivity, and understanding oxidant activation mechanisms in AOPs.

Summary: MnFe Prussian blue analogues (MnFe PBAs) were fabricated and used as catalysts for the degradation of acetamiprid with peroxymonosulfate (PMS) as an oxidant. The most active facets for PMS activation were found to be MnFe PBAs (200) due to their superior chemisorption affinity and electron-transfer ability. The study demonstrated that Mn(III) played a crucial role in adjusting the electron density between Fe and Mn, leading to the high activation performance of MnFe PBAs (200).

Summary: A novel carbon quantum dots decorated C-doped alpha-Bi2O3 photocatalyst (CBO/CQDs) was synthesized and showed significantly improved contaminants removal efficiencies. CBO/CQDs exhibited much higher ceftriaxone sodium degradation rate constant (k) compared to pure alpha-Bi2O3 and C-doped alpha-Bi2O3. The synergistic effect of carbon doping, CQDs loading, and reduced particle size of CBO/CQDs enhanced the utilization of visible light and efficient separation of photogenerated carriers.

Summary: Accurate control of catalytic activity and mechanism, as well as understanding the correlation between structure, activity, and selectivity in Fenton-like chemistry, is crucial for designing efficient catalysts for sustainable water decontamination. In this study, size-dependent catalysts with single cobalt atoms, atomic clusters, and nanoparticles were prepared to investigate the change in catalytic activity and mechanism in peroxymonosulfate-based Fenton-like chemistry. The results showed that the catalytic activity and durability varied with the size of the metal active centers, and the contributions of radical and nonradical mechanisms were modulated by reducing the metal size. Density functional theory calculations revealed the evolution of catalytic mechanisms in size-dependent systems at different Gibbs free energies for reactive oxygen species generation. The findings of this study provide an in-depth understanding of the effects of metal size in Fenton-like chemistry and can guide the design of intelligent catalysts for specific water purification applications.
