“…pH is an important influencing factor for organic pollutant degradation in heterogeneous catalysis systems, as the species distribution of target pollutants varies and the physicochemical properties of solid catalysts change under different pH conditions. 57–59 The effect of pH has rarely been discussed for piezoelectric catalysis systems for non-dye organic pollutant degradation. In our experiment, the BTO piezoelectric catalysis activity was investigated under different pH values ranging from 3.0 to 11.0 (Fig.…”

“…The presence of Ag 0 is confirmed through peaks at 368.19 eV (Ag-3d 5/2 ) and 374.2 eV (Ag-3d 3/2 ). The adopted precursor, synthesis temperature and air atmosphere has favored the formation of Ag 0 in bare and as well as in composite [33][34][35]. The existence of Ag + ions was confirmed through a satellite peak appeared at 365.58 eV.…”

“…The bare AgNbO 3 was able to absorb the wavelength in the range of 200-450 nm. The broadening between 460 and 650 nm with a wavelength maximum lying nearby 575 nm attributes to the plasmon resonance phenomena exhibited by the Ag Nps [33]. The light absorbance property of Co 3 O 4 was observed to be dispersed in the full solar spectrum while the two absorption maxima centered at 350 and 650 nm was linked to the ligand-metal charge transfer that occurred between O 2− to Co 2+ and O 2− to Co 3+ ions, respectively [10,12].…”

In the present study, the charge-carrier recombination of visible light active perovskite silver niobate (AgNbO 3 ) was reduced by forming heterojunction with Co 3 O 4 through simple impregnation and calcination route. The loading percentage of Co 3 O 4 was varied as 2, 5, and 10 wt.%. The XRD study revealed reduced interlayer spacing in the composite due to the replacement of the bigger Ag + ions by the smaller Co 2+ and Co 3+ ions of Co 3 O 4 . It was observed that the light harvesting efficiency of the materials was increased with increased loading of Co 3 O 4 . The TEM and XPS analysis confirmed the presence of Ag nanoparticles over the perovskite in the composite. The electrochemical analysis revealed enhanced charge-carrier number density and increased charge-carrier lifetime in the composite as a result of the presence of both silver and cobalt ions in the lattice. Further this enhanced charge-carrier separation of the composites was established through photocatalysis of Bisphenol-A under both solar and LED light. Charge-trapping study indicated *O 2 − and *OH as the major radicals involved and Z-scheme as the predominant charge transfer pathway for generation of these reactive oxygen species.

“…It can be found that C doping makes the band gap of ZnO wider, and the ternary composites have successfully widened the band gap. From the slope of the straight line in Figure 4c, it can be concluded that ZnO-C and MnO2 are p-type semiconductors [43], however, as a conventional n-type semiconductor [44], ZnO is shown to be p-type because the semiconductor is modified by a large number of impurities, and it is proved from the side that C is successfully doped in ZnO nanospheres. According to the intersection of tangent and x-axis, the flat band potential is 0.73 eV and −0.31 eV, respectively.…”

Unlike many studies on the preparation of Z-scheme heterojunctions by doping precious metals, in this paper we first prepared a core-shell material obtained by C doping in ZnO and then composite with MnO2 to form a heterojunction; that is, a low-cost and highly catalytic ternary composite catalyst was prepared by a simple hydrothermal reaction. Meanwhile, a large amount of experimental data have enabled the heterostructure type as well as the mechanism of photocatalytic performance to be fully demonstrated. It is proven that C as an intermediate medium achieves electron transport while making up the deficiency of ZnO, and constitutes an all-solid state Z-scheme heterojunction, which enables the rapid transfer of photogenerated electron pairs and visible light irradiation to the stream to improve the photocatalytic performance of the composite photocatalyst. In terms of examination of degradation performance, this catalyst showed a high photodegradation rate of tetracycline hydrochloride (TC) of 92.6% within 60 min, and the surface ZnO-C/MnO2 catalysts also showed good degradation effect on practical petrochemical wastewater in CODcr degradation experiments.
