Environment-friendly organic coordination design of Z-scheme heterojunction N-BOB/BiOIO for efficient LED-light-driven photocatalytic and electrochemical performance.

As the climate seriously changes, ecofriendly nanomaterials have attracted tremendous interest in renewable energy as photocatalysis. Herein, we designed a new green bismuth-based Z-scheme BiO slabs coordinate with 2-aminoterephthalic acid (N-BOB)/BiOIO through a simple anion exchange and postsynthetic hydrothermal reaction. FTIR, XRD, FESEM and TEM were employed to characterize the functional groups, structure, and morphologies.

Versatile Functionalization of P25 Conjugated ND Nanocomposites for UV-Mediated Free Radical Scavenging and Facilitates Anti-Inflammation Potential in Human Cells.

In this work, we demonstrated that building different linking groups between nanodiamond (ND) and TiO (P25) could provide more effective protection under oxidative stress and ultraviolet (UV) light irradiation compared with the use of TiO alone. The establishment of ester (-C-O-O-R), amide (-CONH-), and epoxide-amine adduct (-NHCCO-) groups between ND-TiO composites was found to be critical in the generation of reactive oxygen species (ROS) by controlling their charge transfer behaviors. We hypothesized that linking groups between the composites dictate the performance of ROS generation from nano-TiO under UV-light irradiation due to the differences in linking groups.

Co-Doped BiOBrCl hierarchical microspheres display enhanced visible-light photocatalytic performance in the degradation of rhodamine B and antibiotics and the inactivation of E. coli.

In this article, we have synthesized Co-doped BiOBrCl hierarchical nanostructured microspheres, featuring different degrees of Co doping, displaying excellent photocatalytic performance. X-ray diffraction and Raman spectroscopy indicated that the Co ions were successfully doped into the BiOBrCl nanocrystals. The photodegradation rate of rhodamine B mediated by a doped BiOBrCl was 150 % greater than that of the non-doped BiOBr.
