Recent advances in subphthalocyanines and related subporphyrinoids

“…In this case, the role of the SubPc is to improve the catalytic activity by populating the conduction band of these materials which subsequently produce superoxide or hydroxyl radicals. [497][498][499][500][501][502] This SubPcdoping of TiO 2 has also found to improve the catalytic efficiency in hydrogen generation processes. 503 2.7.3.8 Catalysis in lithium batteries.…”

Oxygen Vacancy Defects and Cobalt Nanoparticle-Mediated Charge Separation in Black Ti3+ Self-Doped TiO2 Mesoporous Nanotubes for Enhanced Solar-Driven Hydrogen Evolution and Tetracycline Degradation

“…Accordingly, as shown in Figure B, two types of reactive species contributed to the degradation of TC, and the effect followed the sequence Na 2 -EDTA (h + ) > BQ (·O 2 – ). Moreover, in comparison with other reported materials for the degradation of TC (Table ), our Ti 3+ -d-TiO 2 MNTs/N-d-C/Co NPs ternary composites displayed decent degradation efficiency and capability. ,− …”

In Situ Monitoring Charge Transfer on Topotactic Epitaxial Heterointerface for Tetracycline Degradation at the Single-Particle Level

“…To further determine the main active species, the free-radical trapping experiments were measured using isopropanol (IPA), pbenzoquinone (p-BQ), tetrachloromethane (CCl 4 ), and potassium iodide (KI) as the scavengers of •OH, •O 2− , e − , and h + , respectively. 3,47 As shown in Figure 4d, about 68.23% of TC degraded in 10 min without adding any scavenger. However, the degradation rate of TC is 24.96% with the addition of p-BQ, while the degradation ratios of TC were reduced to 46.2, 62.07, and 61.26%, after adding CCl 4 , IPA, and KI, respectively, implying that the •O 2− played an important role in the photodegradation of TC.…”

“…Moreover, the photocatalytic activity of ST/T-0.5 h is almost unchanged after five cyclic reactions, and the crystalline phase and morphology of ST/T-0.5 h were unchanged (Figures S7 and S8), indicating that the ST/T-0.5 h epitaxial heterojunctions have an excellent stability (Figure c ) . To further determine the main active species, the free-radical trapping experiments were measured using isopropanol (IPA), p -benzoquinone (p-BQ), tetrachloromethane (CCl 4 ), and potassium iodide (KI) as the scavengers of ·OH, ·O 2– , e – , and h + , respectively. , As shown in Figure d, about 68.23% of TC degraded in 10 min without adding any scavenger. However, the degradation rate of TC is 24.96% with the addition of p-BQ, while the degradation ratios of TC were reduced to 46.2, 62.07, and 61.26%, after adding CCl 4 , IPA, and KI, respectively, implying that the ·O 2– played an important role in the photodegradation of TC.…”
