“…However, it also promotes the adhesion of bacteria, leading to the observation of some bacteria on its surface (Figure S4). Regarding the negatively postcharged SnO 2 @RuO 2 , SnO is formed on the surface based on the XPS results (Figure b), which is known as a strong reductant. , With the help of SnO, contact bacteria are effectively killed due to the rapid blockage of DNA transcription and cessation of metabolic activity. , Therefore, benefiting from the contribution of SnO, only a few dead bacteria were observed on the surface of the negatively postcharged SnO 2 @RuO 2 , showing efficient antibacterial activity with an antibacterial rate of 97% when compared with the uncharged one (Figure S4).…”

“…A large number of studies reveal that the metal ions, such as Ag + and Zn 2+ , can kill bacteria efficiently, , but incorporating high doses of Ag + and Zn 2+ leads to necrosis of the surrounding tissues during the long-term service.

Moreover, Sn 2+ is also a metal ion with potential toxicity. , However, unlike the traditionally antibacterial mechanism for metal ions, the chemical states of Sn in SnO 2 nanorods can be controlled via a charging process, i.e., the toxic Sn 2+ can transform to nontoxic Sn 4+ after the discharging.…”

The bacterial infection and poor osseointegration of Ti implants could significantly compromise their applications in bone repair and replacement. Based on the carrier separation ability of the heterojunction and the redox reaction of pseudocapacitive metal oxides, we report an electrically responsive TiO 2 −SnO 2 −RuO 2 coating with a multilayered heterostructure on a Ti implant. Owing to the band gap structure of the TiO 2 −SnO 2 − RuO 2 coating, electron carriers are easily enriched at the coating surface, enabling a response to the endogenous electrical stimulation of the bone. With the formation of SnO 2 −RuO 2 pseudocapacitance on the modified surface, the postcharging mode can significantly change the surface chemical state of the coating due to the redox reaction, enhancing the antibacterial ability and osteogenesis-related gene expression of the human bone marrow mesenchymal stem cells. Owing to the attraction for Ca 2+ , only the negatively postcharged SnO 2 @RuO 2 can promote apatite deposition. The in vivo experiment reveals that the S−SnO 2 @RuO 2 -NP could effectively kill the bacteria colonized on the surface and promote osseointegration with the synostosis bonding interface. Thus, negatively charging the electrically responsive coating of TiO 2 −SnO 2 −RuO 2 is a good strategy to endow modified Ti implants with excellent antibacterial ability and osseointegration.

V/S co‐doped SnO2 bimetal sulfur‐oxides catalysts labeled as (Sn,V)1‐x(S,O)2‐y or (SnVSO) with heterovalent state and oxygen vacancy defect are prepared via a green and facile method. The presence of SnVSO in the heterovalent states of Sn4+/Sn2+ and V5+/V4+ facilitates the rapid transfer of the electrons. It improves the electronic charge lifetime, accelerating the efficiency of the catalytic reduction of pollutants. The V/S co‐doped SnO2 regulates the bandgap energy structure. The hydrazine adjusts the heterovalent metal states to reduce Sn4+ to Sn2+ and V5+ to V4+. Also, it introduces oxygen vacancies to SnVSO to maintain the charge equilibrium and increase the active surface reactive sites, which enhance the catalytic activity. The SnVSO‐3 prepared with 0.4 mL hydrazine exhibits excellent catalytic activity, which wholly reduces 20 ppm of 100 mL methyl orange (MO), rhodamine B (RhB), methylene blue (MB), hexavalent chromium (Cr6+), and 4‐nitrophenol (4‐NP) within 6 min. In addition, the SnVSO‐3 also has good stability after repeated 6 runs with a reduction efficiency of 96.8%. Therefore, the V/S co‐doped SnO2 sulfur oxide catalysts have a promising potential for reducing Cr6+ and organic pollutants.
