The one-pot synthesis of amines from benzyl alcohol (BA) and nitrobenzene (NB) represents a step-economic method. However, reported works typically require more than 3 equiv BA to complete the transfer hydrogenation NB, few studies can achieve selective imines secondary amines. In our previous work, Zr(OH)4 demonstrated both dehydrogenation capabilities. Building on this, another component Cu was introduced enhance its catalytic performance for catalyzing coupling reaction between stoichiometric NB under H2 atmosphere. physical hybrid catalyst + selectively produced imines, while supported Cu/Zr(OH)4 yielded Characterization mechanism experiments revealed that modulating proximity leads (1) different adsorption abilities N-benzylideneaniline (NBA) (2) interactions in close contact, which stabilized electronic structure forming Cu+/Cu0 ion pairs with strong activation ability. This work presents design strategy offers an approach preparation N-benzylaniline.

NIR‐II‐Responsive Chainmail Nanocatalysts for Spatiotemporally Controlled Enzymatic Tumor Therapy

Advanced Healthcare Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 20, 2025

Abstract The clinical translation of metal‐based peroxidase‐like nanozymes for antitumor therapy faces two critical challenges: off‐target catalytic activation and suboptimal hydroxyl radical (•OH) generation efficiency. To address these limitations, an innovative chainmail nanocatalyst featuring nitrogen‐doped carbon‐encapsulated nanoceria is developed, which combines spatial confinement effects with photo‐trigger enhancement. graphitic carbon shell serves as a physical barrier that effectively isolates metallic cerium from the biological environment, reducing nonspecific by 100% compared to bare nanoceria. Remarkably, under 1064 nm laser irradiation, electrons species can penetrate through quantum tunneling effects, activating multiple enzymatic pathways. Vacancy engineering further optimizes Ce 3+ /Ce 4+ redox pair ratio (1.75 vs 0.44 in pristine nanoceria), establishing electron reservoir facilitates amplification H 2 O ‐to‐•OH conversion glutathione oxidase‐mimicking activity tumor microenvironment remodeling. This dual mechanism synergistically elevates intracellular oxidative stress while preserving normal tissue viability. In vivo evaluations demonstrate photoactivated exhibits remarkable suppression efficacy, prolonging survival duration tumor‐bearing mice 33 days 70 days. light‐gated architecture provides paradigm spatiotemporally controlled therapy, resolving dilemma between potency specificity nanozyme design.
