Summary: Researchers have explored a novel photocatalyst by passivating BP nanosheets with PDDA and combining them with BiOBr through a co-precipitation method, enhancing carrier transporting efficiency and inhibiting carrier recombination. This has led to increased light absorption and photocatalytic activity, significantly improving the degradation effects towards methylene orange and ciprofloxacin. The findings demonstrate a new approach in designing solar light driven photocatalysts.

Summary: This study successfully achieved the simultaneous photocatalytic evolution of H-2 and CO by combining single Co2+ sites loaded onto carbon nitride with black phosphorus. The H-2/CO syngas ratios can be controlled by changing the % weight of BP in the system or by the addition of CoCl2 in the reaction solution. The maximum total gas evolution of 70 mu mol g(-1) h(-1) was achieved with 20 wt % BP (BP20%/Co@C3N4) at a H-2/CO ratio of 2.

Summary: Photocatalysis, resembling natural photosynthesis, offers a sustainable solution to environmental threats and energy crisis. The design of a dual Z-scheme photocatalytic system using mixed-phase red/black phosphorus and tungsten oxide effectively enhanced CO2 reduction. The ternary composite material showed enhanced optical absorption capacity and achieved a significant CH4 yield under visible light illumination, surpassing the performance of pristine counterparts. The formation of a dual Z-scheme system and the unique hetero-homo junctions contributed to improved photoconversion performance.

Summary: In this study, surface anchoring of black phosphorus quantum dots (BPQDs) and bulk iron-doping in W18O49 nanowires were shown to significantly enhance the photocatalytic activity for N2 fixation into NH3. The reducing ability of photo-generated electrons was enhanced by Fe-doping, while the N2 adsorption/activation was facilitated by surface BPQD anchoring. The synergistic effect of these two approaches remarkably improved the photocatalytic activity of W18O49 nanowires for NH3 production.

Summary: The Coulomb interactions between excited electrons and holes play a crucial role in the photo-physical processes in 2D semiconductors. In the BP/TiO2 heterojunction, exciton dissociation is driven by the energy difference between the conduction bands, leading to enhanced photocatalytic efficiency through effective exciton dissociation, interfacial charge separation, and charge-carrier accumulation.

Summary: BP photocatalysts have adjustable direct band gaps, wide light absorption ranges, and ultrahigh charge carrier mobility, making them promising nonmetal photocatalysts. However, their poor ambient stability and fast recombination of photogenerated electrons and holes limit their performance. To overcome these limitations, BP-based heterojunction photocatalysts have been developed by combining BP with other catalyst materials.
