A new approach on visible light assisted oxygen doped g-C3N4/β-Bi2O3 direct Z-scheme heterojunction towards the degradation of bisphenol A: Degradation pathway, toxicity assessment, and continuous mode study

Photocatalysis Meets Piezoelectricity in a Type-I Oxygen Vacancy-Rich BaTiO3/BiOBr Heterojunction: Mechanism Insights from Characterizations to DFT Calculations

“…From Figure c, we know that BTBB-10 has the smallest arc radius among these three samples, implying that the combination of BiOBr and BTO can accelerate the transfer of photogenerated e – –h + pairs. Furthermore, the cyclic voltammetry curves (Figure d) show that the integral area of BTBB-10 exceeds those of BiOBr and BTO, indicative of the superior redox capacity for BTBB-10 . On the other hand, this result also manifests that the BTBB-10 exhibits higher electrochemical response than BiOBr and BTO, suggesting that an appropriate amount of BTO can facilitate the transfer of photogenerated electrons in BiOBr.…”

“…Furthermore, the cyclic voltammetry curves (Figure 8d) show that the integral area of BTBB-10 exceeds those of BiOBr and BTO, indicative of the superior redox capacity for BTBB-10. 73 On the other hand, this result also manifests that the BTBB-10 exhibits higher electrochemical response than BiOBr and BTO, suggesting that an appropriate amount of BTO can facilitate the transfer of photogenerated electrons in BiOBr. In the linear sweep voltammetry (LSV) curves (Figure 8e), the current density of BTBB-10 surpasses that of individual BiOBr, also implying a significant enhancement in the separation efficiency of photogenerated e − −h + pairs in the BTBB heterojunction.…”

Efficient photo-oxidation of bisphenol a and tetracycline through sulfur-doped g-C3N4/CD heterojunctions

“…For instance, during the decomposition of BPA by the prepared photocatalyst, intermediate compounds with m / z values of 208, 197, 104, 108, 152, 122, and 135 were detected. 61 Similarly, active species targeted double bonds, aromatic rings, amino groups, leading to ring-opening reactions, loss of functional groups, or rupture of primary carbon bonds, thereby generating many intermediates in the case of TC. The intermediate compounds formed during the decomposition of TC exhibited m / z values of 445, 272, 238, 433, 301, 149, 210, 438, 139, and 103.…”

Enhancing the photocatalytic elimination of acephate residues using Ni0 doped and diatomite-supported NiO: optimization, pathway, and toxicity

“…These methods include photocatalytic, Fenton, sono-chemical, electrochemical, and photo-Fenton's degradation. 29,30 Advanced oxidation techniques effectively decompose and transform organic molecules, yielding environmentally benign and nontoxic products. 31,32 Therefore, numerous micro-and nanostructures have been examined to assess their capacities for the photocatalytic oxidization of organic contaminants.…”
