“…Furthermore, Cl − could also quench hydroxyl radicals (Eq. (12) ) ( Fu et al, 2020 ). Actually, the reaction between SO 4 2− and SO 4 •− was very weak ( Jiang et al, 2021 ), the inhibition of SO 4 2− on ARB removal was attributed to the decreasing of the SO 4 •− /SO 4 2− redox potential.…”

“…Huang et al also reported that citric acid inhibited the degradation of 1-naphthol by reaction with HO • ( Huang et al, 2019 ). On the other hand, the quinones, carboxyl, ketones, and hydroxyl groups in humic acid could accelerate the electron transfer and circulation of iron, thereby promoting the elimination of pollutants ( Fu et al, 2020 ). Therefore, the inhibition and promotion effects may simultaneously act on ARB removal, but the former was more important than the latter in this study.…”

“…[ 16 ] Compared to ferric ions and cobalt ions, copper ions possess a more stable reaction rate and a higher safety profile in the provocative process of sulfate radical. [ 17 ] More importantly, the photothermal treatment often leads to therapeutic skin damage, [ 18 ] while copper ions are capable of promoting angiogenesis, [ 19 ] facilitating maturation of extracellular matrix (ECM) and thus accelerating tissue healing. [ 20 ] Considering all these factors, it is a judicious choice to use CuS NPs in stimuli‐responsive modalities for achieving the oxygen‐independent sulfate radical nanotherapy.…”

Oxygen‐Independent Sulfate Radical for Stimuli‐Responsive Tumor Nanotherapy

Variant modalities are quested and merged into the tumor nanotherapy by leveraging the excitation from external or intratumoral incentives. However, the ubiquitous hypoxia and the insufficient content of hydrogen peroxide (H2O2) in tumor microenvironments inevitably hinder the effective production of reactive oxygen species (ROS). To radically extricate from the shackles, peroxymonosulfate (PMS: HSO5−)‐loaded hollow mesoporous copper sulfide (CuS) nanoparticles (NPs) are prepared as the distinct ROS donors for sulfate radical (•SO4−)‐mediated and stimuli‐responsive tumor nanotherapy in an oxygen‐independent manner. In this therapeutic modality, the second near‐infrared laser irradiation, together with the released copper ions as well as the heat produced by CuS after illumination, work together to activate PMS thus triply ensuring the copious production of •SO4−. Different from conventional ROS, the emergence of •SO4−, possessing a longer half‐life and more rapid reaction, is independent of the oxygen (O2) and H2O2 content within the tumor. In addition, this engineered nanosystem also exerts the function of photoacoustic imaging and skin restoration on the corresponding animal models. This study reveals the enormous potential of sulfate radical in oncotherapy and broadens pave for exploring the application of multifunctional and stimuli‐responsive nanosystems in biomedicine.

“…Physical treatment methods include adsorption and membrane treatment technology; however, pollutants are not degraded and can easily cause secondary pollution [7][8][9]. Chemical oxidation methods mainly degrade various types of pollutants by oxidation and reduction reactions, including ozone oxidation [10], Fenton oxidation [11,12], persulfate oxidation [13,14] and photocatalytic technology [15,16]. Photocatalytic degradation of antibiotics with higher 2 of 15 efficiency and broader applicability has been studied and applied by a large number of scholars at this stage for the treatment of various antibiotic contaminations [17].…”

In recent years, with the large-scale use of antibiotics, the pollution of antibiotics in the environment has become increasingly serious and has attracted widespread attention. In this study, a novel CDs/g-C3N4/BiPO4 (CDBPC) composite was successfully synthesized by a hydrothermal method for the removal of the antibiotic tetracycline hydrochloride (TC) in water. The experimental results showed that the synthesized photocatalyst was crystalline rods and cotton balls, accompanied by overlapping layered nanosheet structures, and the specific surface area was as high as 518.50 m2/g. This photocatalyst contains g-C3N4 and bismuth phosphate (BiPO4) phases, as well as abundant surface functional groups such as C=N, C-O, and P-O. When the optimal conditions were pH 4, CDBPC dosage of 1 g/L, and TC concentration of 10 mg/L, the degradation rate of TC reached 75.50%. Active species capture experiments showed that the main active species in this photocatalytic system were holes (h+), hydroxyl radicals, and superoxide anion radicals. The reaction mechanism for the removal of TC by CDBPC was also proposed. The removal of TC was mainly achieved by the synergy between the adsorption of CDBPC and the oxidation of both holes and hydroxyl radicals. In this system, TC was adsorbed on the surface of CDBPC, and then the adsorbed TC was degraded into small molecular products by an attack with holes and hydroxyl radicals and finally mineralized into carbon dioxide and water. This study indicated that this novel photocatalyst CDBPC has a huge potential for antibiotic removal, which provides a new strategy for antibiotic treatment of wastewater.
