Summary: A two-step method was used to prepare B-doped g-C3N4 nanosheets. The multi-layer porous morphology increases the transmission pathway of visible light, enhancing its capture ability. B doping decreases the bandgap and increases the sensitivity of g-C3N4 to visible light. The best performing photocatalyst for nitrogen fixation was found to be 2 wt% B/g-C3N4, which exhibited a nitrogen fixation efficiency 2.44 times higher than g-C3N4 (81.56 mol/L-1.h-1 vs 33.52 mol/L-1.h-1). Additionally, 2 wt% B/g-C3N4 showed strong photocatalytic stability.

Summary: Here, we presented the fabrication of well-crystalline metal-doped BiOCl nanoscale photocatalytic materials through solvothermal synthetic route. Ni doping significantly improved the photocatalytic and antibacterial behavior of BiOCl. The morphological study showed that different metal dopings led to the formation of nanosheet (Ni, Cd), nanoflower (Mo), and nanodisc (Co) morphologies, while Ni doping resulted in large size nanosheets with increased surface area and improved porous structure. The inclusion of Ni into BiOCl nanostructure shifted the band gap and reduced electron-hole recombination, contributing to its excellent photocatalytic performance. Additionally, Ni-BiOCl exhibited excellent photocatalytic antibacterial activity against S. aureus bacteria under visible light.
