Summary: In this study, AgBr/Ag3PO4 heterojunctions were prepared using a precipitation method assisted by 1methoxyethyl-3-methylimidazolium bromide salt ([MOEMIm]Br). The photocatalytic activity of the samples was evaluated by degrading rhodamine B (RhB) and tetracycline (TC). The results showed that the sample with a molar ratio of 8% AgBr/Ag3PO4 exhibited the best activity with visible light, with a degradation rate constant of RhB about 34 times higher than that on Ag3PO4.

Summary: A simple chemical precipitation method was used to synthesize a quaternary composite photocatalyst Ag/Ag3PO4-BiOBr-C3N4 with tuned band gap for enhanced photocatalytic performance. The as-prepared photocatalysts were characterized and evaluated for the degradation of reactive red (RR 120) under visible-light illumination. The Ag/Ag3PO4-BiOBr-C3N4 composite exhibited significantly higher degradation efficiency compared to pristine Ag/Ag3PO4, BiOBr, and C3N4 particles. The work has provided important guidance in designing photocatalysts with surface plasmon effect.

Summary: Environmental pollution caused by organic pollutants, including POPs, has become a matter of increasing concern. Developing an effective decontamination method is highly necessary. In this study, we constructed and characterized a BiOCl/Ag3PO4 (BAP) heterojunction via hydrothermal method. The interaction between BiOCl and Ag3PO4 in BAP promotes the separation and transfer of photo-generated carriers, leading to enhanced photocatalytic activity. BAP effectively degrades various organic pollutants, including POPs, with superoxide radical serving as the most active species in the decontamination process. A possible photo-degradation mechanism by BAP is proposed.

Summary: Electrically controlling the emissivity is a low-energy-consuming solution for thermal radiation manipulation. Graph-diyne (GDY) has the potential to regulate emissivity due to its adjustable bandgap, abundant pores, physical stability, and electrochemical activity. A GDY nanowall with an intrinsic emissivity of 0.66 in the wavelength of 2-20 μm was successfully synthesized. The GDY-based emissivity modulator demonstrated a unique capacity to modulate emissivity under a negative voltage. In situ Raman characterization revealed changes in the alkyne bonds of GDY, which may explain its novel emissivity tunability.
