Summary: In this study, a Z-scheme Ag/SnS2/g-C3N4 heterojunction photocatalyst with excellent photocatalytic performance was prepared. Silver nanoparticles were deposited in the SnS2/g-C3N4 composite through UV photoreduction. The photocatalytic properties of the fabricated material were characterized and its application in Rhodamine B degradation under low-power visible light irradiation was investigated. The results showed that the ternary material with a mass ratio of SnS2: g-C3N4 of 5:95 and a silver doping amount of 0.0022wt% exhibited the highest photocatalytic activity, being 9.09 and 5.73 times higher than that of single g-C3N4 and SnS2/g-C3N4, respectively. The improved photocatalytic activity was attributed to the Z-scheme heterojunction, localized surface plasmon resonance (LSPR) caused by deposited silver, and efficient separation of photoelectron-hole pairs.

Summary: By engineering oxygen vacancies, a 2D/2D heterojunction photocatalytic material of MoO3/g-C(3)N(4) is synthesized and shows excellent performance in H-2 evolution and tetracycline degradation. The high photocatalytic ability of this material mainly comes from the interfacial interaction, efficient charge separation, and strengthened redox potential due to oxygen vacancies.

Summary: In this study, a photocatalytic textile was prepared by spraying heterostructures of oxygen vacancies (OVs)-rich bismuth oxide (BiO2-x) and urea-derived graphitic carbon nitride (UCN) on a modified poly(acrylonitrile) nonwoven textile (APAN). The photocatalytic textile showed excellent activity for sulfamethazine (SMT) removal and bacterial disinfection under white light emitting diodes (LEDs) irradiation. The enhanced photocatalytic performance was attributed to the formation of oxygen vacancies and heterostructures.

Summary: This research successfully prepared a direct Z-scheme g-C3N4/MoO3 photocatalytic composite with oxygen vacancies through a facile in situ method, demonstrating superior photocatalytic performance. The migration and separation of photoinduced charge carriers in the composite material follow a possible mechanism based on the Z-scheme photocatalytic system constructed by the oxygen vacancies.

Summary: The study demonstrated that Mo6+ ions were primarily attached to the surface of g-C3N4 through solution impregnation and transformed into oxides through calcination, enhancing the material's absorption in the visible region. Various analytical tools confirmed the impact of increasing Mo6+ coating on the photocatalytic performance of the material, while also pinpointing the optimal Mo6+ loading thickness as 3%.

Summary: Graphite carbon nitride (g-C3N4) has advantages such as a unique two-dimensional structure, low cost, nontoxic properties, suitable bandgap, and favorable stability. However, its photocatalytic efficiency is suboptimal due to low solar absorptivity and fast recombination of charge pairs. In this study, modified g-C3N4 materials with carbon vacancies (CVs) were obtained through calcination in a hydrogen atmosphere, resulting in higher specific surface area and more active sites. The CVs in the N-(C3) bond reduced electron density and narrowed the bandgap of the modified material, leading to improved light response capability. Under the synergy of abundant pore construction and CVs, the photo-excited charge pairs were effectively separated and transferred, resulting in a significantly higher hydrogen generation rate compared to g-C3N4. The study provides a meaningful method to enhance the photocatalytic performance of photocatalysts by constructing abundant CVs.

Summary: This work aims to enhance the photocatalytic activity of g-C3N4 nanosheets through the insertion of a thiophene group and modification of La-2(MoO4)(3) nanoparticles. The insertion of the thiophene ring extends the optical property of g-C3N4 and promotes electron delocalization. La-2(MoO4)(3) loaded on the surface of thiophene-inserted g-C3N4 facilitates electron migration and suppresses the recombination of electron-hole pairs, resulting in enhanced photoactivity. The La-2(MoO4)(3)/TPCN composite exhibits a significantly higher degradation rate than g-C3N4 and TPCN, and shows good stability in photocatalytic degradation.

Summary: This study presents the ultrasonic fabrication of MoO3-g-C3N4 photocatalyst, resulting in substantially improved photocatalytic performance. XRD and FTIR analysis confirmed the orthorhombic phase of MoO3-g-C3N4. SEM images revealed the oblate-like structure of g-C3N4 and nano rod-like morphology of MoO3 and MoO3-g-C3N4. The photocatalytic properties were evaluated through photoelectrochemical and photodegradation measurements, demonstrating that MoO3-g-C3N4 exhibited significantly higher photocurrent density and better degradation efficiency compared to pure MoO3 and g-C3N4. The efficient charge separation and transfer observed in MoO3-g-C3N4 can be attributed to the heterojunctions formed between g-C3N4 and MoO3, reducing charge recombination and enhancing photocatalytic performance.
