Summary: Doping engineering of metallic elements is important in photocatalysis, especially in the transition element range, as it increases carrier concentration and absorption in the light region. Mn doping changes the local structure of BiOCl, increasing the specific surface area and mesoporous distribution. The combination of Mn doping and metal Bi reduces the forbidden bandwidth, strengthening the photocatalytic ability. The dual-technology combination of Mn doping and Bi metal has promising applications in environmental remediation.

Summary: In this study, a novel type of hollow hierarchical porous TiO2/Ag composite microsphere with tunable microstructure was successfully prepared. Compared with hollow hierarchical porous TiO2 microspheres, the composite microspheres showed a shift in excitation wavelength towards visible light direction, improved response range and light utilization rate. The optimal addition amount of Ti and Ag resulted in specific surface area of 177 m2/g, pore volume of 0.37 cm3/g, and primary and secondary pore sizes of 4.04 nm and 7.74 nm, respectively. They exhibited the highest photocatalytic activity towards 365 nm and 395 nm ultraviolet light, with degradation rates of methyl orange solution reaching 96.84% and 98.65%, respectively. Their excellent performance was attributed to the unique combination of hierarchical pores and hollow structures, as well as the synergistic effect of Ag and TiO2.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
