Summary: In this study, waste pigeon guano (PG) was used as a biomass adulterant to enhance the photocatalytic activity of graphitic carbon nitride (g-C3N4). A novel porous multielement-doped g-C3N4 photocatalyst (CN-PG-S) was fabricated using waste PG and melamine as precursors. The CN-PG-S exhibited abundant porous structures, high conductivity, and excellent photocatalytic abilities, leading to significantly improved H2-production and Cr(VI) reduction compared to pristine g-C3N4. The study highlighted the role of non-metallic and metallic elements in expanding visible-light absorption and facilitating charge separation, and the importance of the porous nanosheet structure in enhancing photocatalytic efficiency.

Summary: The further development of an efficient and sustainable water treatment requires the development of a very active and controllable photocatalyst. In this study, a CNO/g-CN photocatalyst was synthesized and shown to efficiently reduce Cr(VI) and degrade organic dyes under visible light. The unique characteristic of this photocatalyst is its low recombination rate of electron-hole pairs. This study opens an alternative route for effective binary photocatalysts in environmental remediation.

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: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
