Aqueous zinc-ion batteries (AZIBs) have significant potential as a large-scale energy storage device due to their low cost and high safety. However, the formation of zinc dendrites during repeated plating and stripping and complicated side reactions has seriously hindered the development of AZIBs. Herein, a N, P dual-doped biomass carbon was constructed by a simple hydrothermal and pyrolysis strategy. In this case, N and P heteroatoms increased the defects of biomass carbon and made it easier to form a uniform and stable interface with the zinc metal. On the other hand, the interfacial interactions between Zn2+ and the biomass carbon surface were enhanced by the introduction of zincophilic groups, which lowered the energy barriers required for zinc nucleation, resulting in uniform zinc deposition. Therefore, symmetric batteries assembled with Zn anodes based on N and P dual-doped biomass carbon exhibited outstanding cycling stability (2000 h) and relatively small voltage hysteresis (45 mV) at a current density of 1 mA cm–2 and an area capacity of 0.15 mAh cm–2. Besides, with a VO2 cathode to compose a full battery, the capacity of the NPBC@Zn//VO2 battery was 132.2 mAh g–1 after 1500 cycles at 5 A g–1, with 76.8% capacity retention. It is much higher than the 27.7% of the Zn//VO2 battery. This work demonstrates a novel two-element-doped biomass carbon/Zn anode interface modification strategy to achieve dendrite-free Zn anodes in AZIBs.

“…Among these strategies, heterojunction structures are considered to be one of the most effective ways to overcome charge transfer barriers. In order to improve the quantum efficiency of BVO and solve the problem of TiO 2 wide band gap, BVO/TiO 2 heterostructured photocatalysts were prepared . Therefore, the binding of TiO 2 to BVO may be a potential pathway that not only extends the light absorption of TiO 2 into the visible range but also enhances the transfer of charge carriers by forming heterojunctions at the interface .…”

Environmental issues, such as increasingly polluted water resources and energy shortages, have led to the need for new strategies to promote sustainable progress and enhance human wellbeing. Photocatalysis is widely recognized as a promising technology for environmental sustainability. MXene is a two-dimensional nanotransition metal material, which has attracted extensive attention in the field of photocatalysis. In MXenes, titanium carbide (Ti 3 C 2 ) has been extensively studied for its application in photocatalysis due to its unique nanolayered structure. The Ti site on the surface of Ti 3 C 2 has a stronger redox activity than traditional C materials, and Ti 3 C 2 has high electrical conductivity. The focus of this study is to obtain the Ti 3 C 2 /TiO 2 composite by in situ calcination of Ti 3 C 2 and then combine Mo,W:BVO with TiO 2 to form feasible heterojunctions. The excellent electrical conductivity of Ti 3 C 2 promotes the transfer of electrons and holes between Mo,W:BVO and TiO 2 , thus establishing a cascade that minimizes charge carrier recombination and exhibits strong photocatalytic activity. Through a series of photocatalytic tests, the optimum calcination temperature and time of Ti 3 C 2 (550 °C, 2.5 h) and the doping amount of Ti 3 C 2 (2 mg/mL) were determined. Under these conditions, a high current density of 3.8 mA cm −2 was obtained, showing excellent photostability. This study confirmed the strong photocatalytic activity of the synthesized nanoscale composites Mo,W:BVO/TiO 2 /Ti 3 C 2 , providing valuable insights for the design of efficient and sustainable photocatalysts in the future.

Molybdenum trioxide (MoO3) possesses high energy density but often suffers from poor electrical conductivity and limited cycling stability when used as a sodium‐ion battery (SIB) anode. To address these issues, the construction of （Molybdenum trioxide‐Molybdenum disulfide）MoO3‐MoS2 heterostructures has proven effective in enhancing electronic conductivity, ion diffusion properties, and structural stability. Guided by the density functional theory (DFT) calculations, which predict favorable Na+ diffusion and adsorption properties, nanorod‐like MoO3‐MoS2 heterostructures are synthesized using a two‐step method. Benefiting from the synergistic effects of the heterostructure and nanosized morphology, the resulting MoO3‐MoS2 electrode exhibits outstanding rate performance (316 mA h g−1 at 10 A g−1) and long‐lasting cycling stability (286 mA h g−1 after 2300 cycles at 5 A g−1) as an SIB anode. In situ XRD measurements reveal that the ultrahigh specific capacity of MoO3‐MoS2 is attributed to the synergistic intercalation‐conversion storage of MoO3 and MoS2. In the pursuit of meeting commercialization requirements, electrodes with adjustable mass loading are also prepared using 3D printing, showcasing the high areal capacity characteristics of the SIBs. This study not only provides theoretical insights into expanding the use of heterojunction materials as SIB anodes but also demonstrates the significant potential for creating high‐energy‐density and cost‐effective SIBs.
