| 英文摘要 | Biofouling on marine equipment is a significant worldwide issue causing environmental harm and economic losses. Drawing inspiration from the natural defense mechanisms of marine algae, an innovative oxygen vacancy engineering strategy is presented to develop advanced haloperoxidase-like based on bismuth molybdate (OVs-BMO). The critical need for interfacial activity modulation is achieved through deliberate vacancy engineering, creating abundant oxygen vacancies and increasing specific surface area that serve as both catalytic active sites and surface charge modulation centers. The engineered OVs-BMO nanozymes demonstrate remarkable catalytic activity, with a bromination reaction rate of 0.15 mu M min-1 at a concentration of 0.05 mg mL-1, which represents a 36-fold enhancement in efficiency compared to pristine bismuth molybdate (BMO). The breakthrough in haloperoxidase-like activity stems from our precisely controlled vacancy architecture and increased specific surface area that optimizes: surface electron density redistribution, reactive oxygen species generation efficiency, substrate adsorption-desorption dynamics and surface-active site number. Moreover, under natural seawater conditions, OVs-BMO exhibits significant antibacterial effectiveness against various bacterial strains. Exposure to low concentrations of H2O2 at 25 mu M, 350 mu M, and 100 mu M results in notable bacterial inhibition rates of 80 %, 91 %, and 92 % against E. coli, S. aureus, and P. aeruginosa, respectively. The interfacial engineering strategy presented provides a novel paradigm for designing marine antifouling materials that combine enzymatic catalysis with physical anti-adhesion mechanisms, offering significant potential for sustainable ocean technology development. |
