Abstract With the promotion of nanochemistry research, large numbers nanomaterials have been applied in vivo to produce desirable cytotoxic substances response endogenous or exogenous stimuli for achieving disease‐specific therapy. However, performance is a critical issue that difficult improve and optimize under biological conditions. Defect‐engineered nanoparticles become most researched hot materials biomedical applications recently due their excellent physicochemical properties, such as optical properties redox reaction capabilities. Importantly, can be easily adjusted by regulating type concentration defects without requiring other complex designs. Therefore, this tutorial review focuses on defect engineering briefly discusses classification, introduction strategies, characterization techniques. Several representative defective are especially discussed order reveal relationship between properties. A series disease treatment strategies based engineered summarized. By summarizing design application nanomaterials, simple but effective methodology provided researchers therapeutic effects nanomaterial‐based platforms from science perspective.

Photoelectrochemical nitrate reduction reaction (PEC NIRR) could convert the harmful pollutant (NO3-) to high-value-added ammonia (NH3) under mild conditions. However, catalysts are currently hindered by low catalytic activity and slow kinetics. Here, we reported a heterostructure composed of CeO2 BiVO4, "frustrated Lewis pairs (FLPs)" concept was introduced for understanding role acids bases on PEC NIRR. The electron density difference maps indicated that FLPs were significantly active adsorption activation NO3-. Furthermore, carbon (C) improved carrier transport ability kinetics, contributing NH3 yield 21.81 μg h-1 cm-2. conversion process NO3- tracked 15NO3- 14NO3- isotopic labeling. Therefore, this study demonstrated potential CeO2-C/BiVO4 efficient NIRR provided unique mechanism over FLPs.

Increasing the yield of reactive oxygen species (ROS) to enhance oxidative stress in cells is an eternal goal cancer therapy. In this study, BiVO4 artificial nanozyme developed with adjustable vanadium vacancy for ultrasound (US) enhanced piezoelectric/sonodynamic Under US excitation, vacancy-rich nanosheets (abbreviated Vv -r NSs) facilitate generation a large number electrons improve ROS yield. Meanwhile, mechanical strain imposed by irradiation makes NSs display typical piezoelectric response, which tilts conduction band be more negative and valance positive than redox potentials O2 /O2•- H2 O/·OH, boosting efficiency generation. Both density functional theory calculations experiments confirm that introduction cationic can sonodynamic effect. As expected, have better peroxidase enzyme catalytic glutathione depletion activities, resulting increased intracellular stress. This triple amplification strategy induced substantially inhibits growth cells. The work may open avenue achieve synergetic therapy introducing vacancy, broadening biomedical use materials.

Photoelectrochemical (PEC) water splitting for hydrogen evolution has been considered as a promising technology to solve the energy and environmental issues. However, solar-to-hydrogen (STH) conversion efficiencies of current PEC systems are far from meeting commercial demand (10%) due lack efficient photoelectrode materials. The recent rapid development defect engineering photoelectrodes significantly improved performance, which is expected break through bottleneck low STH efficiency. In this review, category construction methods different defects in materials summarized. Based on in-depth summary analysis existing reports, performance enhancement mechanism critically discussed terms light absorption, carrier separation transport, surface redox reactions. Finally, application prospects challenges presented, future research directions field also proposed.

Abstract The oxygen evolution reaction, which involves high overpotential and slow charge-transport kinetics, plays a critical role in determining the efficiency of solar-driven water splitting. chiral-induced spin selectivity phenomenon has been utilized to reduce by-product production hinder charge recombination. To fully exploit polarization effect, we herein propose dual spin-controlled perovskite photoelectrode. three-dimensional (3D) serves as light absorber while two-dimensional (2D) chiral functions polarizer align states carriers. Compared other investigated organic cations, R -/ S -naphthyl ethylamine enable strong spin-orbital coupling due strengthened π–π stacking interactions. resulting naphthyl ethylamine-based 2D/3D photoelectrodes achieved polarizability 75%. Moreover, relaxation was prevented by employing spin-selective L -NiFeOOH catalyst, enables secondary alignment promote generation triplet oxygen. This photoanode achieves 13.17% applied-bias photon-to-current efficiency. Here, after connecting photocathode with -NiFeOOH/ series, co-planar water-splitting device exhibited solar-to-hydrogen 12.55%.
