Abstract Layered double hydroxides (LDHs) can serves as catalysts for CO 2 photocatalytic reduction (CO PR). However, the conventionally synthesized LDHs undergo undesired aggregation, which results in an insufficient number of active sites and limits desirable electron transfer required PR. The metal‐organic framework (MOF) template‐grown demonstrate excellent promise exploiting strengths both MOFs LDHs. Herein, situ growth MIL‐68(In)‐NH MOF‐templated Co–In bimetallic catalyst (CoIn‐LDH/MOF) having ultrathin nanosheet morphology on preserved rod‐like MOF template is demonstrated. Compared to grown LDH (CoIn‐LDH), CoIn‐LDH/MOF not only exposes more but also possesses hydroxyl vacancies ( V OH ) Co ). Thus, performs a higher generation rate 2320 µmol g −1 h during PR, demonstrating improved activity selectivity than those CoIn‐LDH. Experiments coupled with calculations reveal that CoIn‐LDH/MOF‐driven PR follows * COOH pathway. lower energy barriers formation CO(g) be attributed coexistence CoIn‐LDH/MOF, effectively promoting charge enhancing performance. This study provides new strategy obtain high‐performant LDH‐based morphology.

Abstract Recently, layered double hydroxides (LDH) have shown great potential in photoreduction of CO 2 owing to its flexible structural adjustability. In this study, the mild acidic property tannic acid (TA) is exploited etch bimetal LDH create abundant vacancies gain coordination unsaturated active centers. Based on different chelating abilities TA various metal ions, metals are remained by selective chelation while inert removed during etching process LDH. Furthermore, with ions not only increases percentage highly but also compensates for damage caused etch, which achieves a scalpel‐like construction vacancies. The NiAl‐LDH etched and functionalized 3 h exhibits superior photo‐reduction performance without co‐catalysts photo‐sensitizers, 14 times that pristine NiAl‐LDH. fact many LDHs can be exhibit significantly improved photocatalytic efficiency confirmed, suggesting strategy generalized functionalize double‐ or multi‐metal method provided work opens door polyphenol‐functionalized enhance their ability light‐driven chemical transformations.

ABSTRACT Regulated cell death (RCD) is considered a vital process in cancer therapy, determining treatment outcomes and facilitating the eradication of cells. As an emerging type RCD, PANoptosis features excellent antineoplastic effects due to its combination modes, including pyroptosis, apoptosis, necroptosis. In this work, anion‐cation vacancies (oxygen/titanium‐vacancy‐rich) ultrathin HTiO nanosheets with outstanding sonocatalytic performance peroxidase‐mimicking activity are rationally engineered for disruption mitochondrial function tumor cells destabilization redox homeostasis, ultimately inducing PANoptosis. The utilization external ultrasound energy amplifies production toxic reactive oxygen species (ROS). Density functional theory calculations indicate that titanium generated enhance ROS generation efficiency by promoting carrier separation increasing adsorption capacity H 2 O . advantages triggering substantially evidenced exceptional efficacy both at cellular level on two vivo separate xenografts (4T1 MDA‐MB‐231 breast tumors). This work highlights distinct titanium‐based nanostructure multimodal synergistic integration enzymatic therapies, offering alternative but highly efficient strategy fabricating vacancy‐engineered biomaterials optimized therapeutic treatment.

Abstract The efficient photocatalytic reduction of CO 2 into value‐added chemicals is significantly challenged by the charge carrier separation and transfer kinetics photocatalysts as well thermodynamics process. Herein, it proposes a heterojunction with asymmetric W‐Cl anion layer in Bi WO 6 (abbreviated BWOC). results unbalanced electron density distribution thus enables to establish atomic‐level donor–acceptor structure larger electrostatic potential heterojunction, which facilitate kinetics. Simulation on intermediates photoreduction process demonstrates that possesses smaller energy barrier for rate‐determining step *COOH endothermic formation, thermodynamically more favorable generate further confirmed detection over situ Fourier transform infrared spectroscopy. As result, BWOC achieved rather high yield value 32.11 µmol g − ¹ h nearly four times higher than pure . construction this work provides new insights design systems toward reduction.

Abstract Despite its potential in hydrogen (H 2 ) therapy, ammonia borane (AB) has limited biomedical applications due to uncontrolled hydrolysis rate and cause cytotoxicity. Existing material‐based delivery strategies focus on accelerating AB for H production, hence exacerbating these issues. A new nanoconfinement strategy is reported, which loads onto oxygen‐deficient, hybrid‐phased titanate nanocrystals implant surfaces through a unique one‐end‐anchored docking (OEAD) mechanism. This effectively restricts the release of molecules, allowing only water molecules infiltrate interlayer space slow sustained release. significantly prolongs duration circumvents cytotoxicity associated with interacting peroxide O inflammatory microenvironment. In vitro vivo have shown that from surface alleviates diabetes‐related oxidative stress, combined magnesium ions (Mg 2+ synergistically promotes innervated‐vascularized bone regeneration.
