Summary: In this study, two-dimensional BiOBr nanomaterials with oxygen-rich and oxygen-poor vacancies were designed and their photocatalytic activities were investigated. It was found that the oxygen-rich BiOBr exhibited higher antibacterial activity under NIR light irradiation due to its optimized electronic structure, which resulted in stronger interactions with bacteria, higher absorption capacity to NIR light, and longer photocarrier lifetime. The DFT calculations also showed that the oxygen-rich BiOBr had better O2 adsorption, leading to the generation of more reactive oxygen species for superior activity.

Summary: Doping S into the lattice of BiOBr to synthesize S-BiOBr significantly enhances the degradation efficiency and kinetic constant for the visible-light-driven degradation of ibuprofen. This is attributed to the band structure tuning by S-doping, leading to higher visible light utilization efficiency. OH radicals play a synergistic role with holes in the degradation process on S-BiOBr, which is more efficient than the reported single hole- or superoxide-dominant reactions.

Summary: This study presents the successful fabrication of Z-scheme heterojunctions consisting of Yb-doped manganese oxide (MnO2) and nitrogen-doped carbon quantum dots (N-CQDs), achieving efficient photocatalytic degradation of tetracycline (TC) and bacterial destruction. The Yb-doped MnO2/N-CQDs showed superior photocatalytic activity compared to Yb-doped MnO2, with a remarkable removal rate of 97.88% for TC under simulated solar light. The Yb-doped MnO2/N-CQDs also exhibited excellent bactericidal activity with no observed bacterial resistance even after 20 consecutive trials. The Z-scheme heterojunctions between Yb-doped MnO2 and N-CQDs facilitate the separation of electron-hole pairs and promote the generation of reactive oxygen species, contributing to the remarkable photocatalytic activity.

Summary: This study demonstrates the improved thermoelectric performance of Bi2Te3 nanosheets grown on reduced graphene oxides (rGO) through the formation of heterointerfaces. The phonon scattering effect and extra carrier transport channels induced by the rGO-Bi2Te3 heterointerface lead to an enhanced power factor value and reduced thermal conductivity. Furthermore, the photo-thermoelectric catalysis of rGO-Bi2Te3 significantly increases the yield of reactive oxygen species. This study provides new insights into heterointerface design in photo-thermoelectric catalysis.

Summary: Confering catalytic defects in sonosensitizers is crucial for enhancing sonodynamic therapy. In this study, 2D catalytic planar defects were designed within Ti3C2 sheets to overcome this challenge. These planar slip dislocations with abundant Ti3+ species can activate O-2, resulting in a significant amount of O-1(2) generation and a high bactericidal capability under ultrasound stimulation. It was found that the 2D catalytic planar defects can intervene in electron transfer through the phonon drag effect, leading to a dramatic decrease in O-2 activation energy.

Summary: A rapid and effective therapeutic strategy for treating osteomyelitis is reported, utilizing ferroelectric polarization interfacial engineering of BiFeO3/MXene (Ti3C2) triggered by ultrasound. The ferroelectric polarization induced by ultrasound leads to the formation of a piezoelectric field, and the sonoluminescence effect stimulates BiFeO3/Ti3C2 to produce photogenerated carriers. With the synergistic action of the polarization electric field and Schottky junction, the separation of electrons and holes is accelerated, improving the utilization of polarized charges and photogenerated charges, and enhancing the yield of reactive oxygen species. This approach efficiently kills Staphylococcus aureus in a short time with the assistance of ultrasonic heating.
