“…reported that a small amount of carbon doped with Ti 4 O 7 promoted electron transport, but long-term operation led to carbon material oxidation. Introducing metallic elements can enhance the stability of Ti 4 O 7 while improving its electrochemical properties (Feng et al, 2022;Huang et al, 2020;Xu et al, 2022). Moreover, Pd-Cu co-doped Ti 4 O 7 exhibited superior degradation performance for sulfamethoxazole (Misal et al, 2020).…”

Elemental doping is a promising way for enhancing the electrocatalytic activity of metal oxides. Herein, we fabricate Ti/ Ti4O7-CB-Ce anode materials by the modification means of carbon black and Cerium co-doped Ti4O7, and this shift effectively improve the interfacial charge transfer rate of Ti4O7 and •OH yield in the electrocatalytic process. Remarkably, the Ti4O7-CB-Ce anode exhibits excellent efficiency of minocycline (MNC) wastewater treatment (100 % removal within 20 minutes) and the removal rate reduces from 100 % to 98.5 % after 5 cycles, which is comparable to BDD electrode. •OH and 1O2 are identified as the active species in the reaction. Meanwhile, it’s discovered that Ti/ Ti4O7-CB-Ce anodes can effectively improve the biochemical properties of the non-biodegradable pharmaceutical wastewater (B/C values from 0.25 to 0.44) and significantly reduce the toxicity of the wastewater (luminescent bacteria inhibition rate from 100 % to 26.6 %). This work paves an effective strategy for designing superior metal oxides electrocatalysts.

Magnéli phase titanium suboxides (M‐TSOs) belong to a type of sub‐stoichiometric titanium oxides based on the crystal structure of rutile TiO2. They possess a unique shear structure, granting them exceptional electrical conductivity and corrosion resistance. These two advantages are crucial for electrode materials in electrochemistry, hence the significant interest from numerous researchers. However, the preparation of M‐TSOs is uneconomic due to high temperature reduction and other complex synthesis process, thus limiting their practical application in electrochemical fields. This review delves into the crystal structure, properties, and synthesis methods of M‐TSOs, and touches on their applications as electrocatalysts in wastewater treatment and electrochemical water splitting. Furthermore, it highlights the research challenges and potential future research directions in M‐TSOs.

Elemental doping is a promising way for enhancing the electrocatalytic activity of metal oxides. Herein, we fabricate Ti/ Ti 4 O 7 -CB-Ce anode materials by the modi cation means of carbon black and Cerium codoped Ti 4 O 7 , and this shift effectively improve the interfacial charge transfer rate of Ti 4 O 7 and •OH yield in the electrocatalytic process. Remarkably, the Ti 4 O 7 -CB-Ce anode exhibits excellent e ciency of minocycline (MNC) wastewater treatment (100 % removal within 20 minutes) and the removal rate reduces from 100 % to 98.5 % after 5 cycles, which is comparable to BDD electrode. •OH and 1 O 2 are identi ed as the active species in the reaction. Meanwhile, it's discovered that Ti/ Ti 4 O 7 -CB-Ce anodes can effectively improve the biochemical properties of the non-biodegradable pharmaceutical wastewater (B/C values from 0.25 to 0.44) and signi cantly reduce the toxicity of the wastewater (luminescent bacteria inhibition rate from 100 % to 26.6 %). This work paves an effective strategy for designing superior metal oxides electrocatalysts. Highlights 1. CB-Ce co-doped Ti 4 O 7 anodes reduce 100 % MNC and 40 % COD from wastewater. 2. Ti/Ti 4 O 7 -CB-Ce shows better performance than Ti/SnO2-Sb, Pt-Ir and BDD anodes. 3. Co-doping of CB-Ce can improve the charge transfer rate and the yield of •OH. 4. Ti/Ti 4 O 7 -CB-Ce anodes improve the B/C values and reduce the toxicity of wastewater.
