Ultrathin 2D In2O3 Nanosheets Confining Cu Single Atoms Synergized With Oxygen Vacancies for High Selectivity of Photocatalytic Reduction of CO2 to CO

Advanced Science, EarlyView.
In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure based on oxygen vacancies (OV)‐rich defects and low crystallinity to anchor Cu single atoms (Cu SAs) and synthesized Cu/In2O3‐Ns photocatalysts. ABSTRACT In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure ...

Permanent Oxidative Dipole Engineering in Quinoline COFs for Boosting Exciton Dissociation and Oxygen Activation in H2O2 Photosynthesis

Advanced Science, EarlyView.
Permanent oxidative dipole (POD) engineering overcomes the electronic uniformity of quinoline‐linked COFs. By enhancing the dipole moment to 2.08 D and lowering exciton binding energy to 20.3 meV, it constructs a robust built‐in electric field and spatially decoupled redox centers. This bypasses inherent kinetic bottlenecks, achieving a 4569 µmol g−1 h−

Unlocking Li/Mg‐Based Photochemical Nitration Platforms for Anticancer Drug Discovery

Advanced Science, EarlyView.
Two low‐toxicity light main‐group metal photochemical systems based on lithium and magnesium are constructed for selective C(sp2)‐H (di)nitration of anilines. The obtained dinitrated products exhibit anti‐HCC (hepatocellular carcinoma) and anti‐KYSE30 cell activities, holding promise as novel antitumor candidates.

Unlocking Zenith Electronic State of Ni Sites in Ligand‐Engineered COFs for Efficient •O2−‐Driven Uranium Photoreduction

Advanced Science, EarlyView.
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.

Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion

Advanced Science, EarlyView.
We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

Self‐Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis

Advanced Science, EarlyView.
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.

Dual Impact of Long‐Lived Localized Carriers Induced by Restricted Hole Transfer in Organic Photovoltaics and Photocatalytic Hydrogen Evolution

Advanced Energy Materials, EarlyView.
This work clarifies why organic semiconductors perform differently in photovoltaic devices and photocatalytic nanoparticles. By examining D18:Y5 and PM6:Y6 systems, we show how aggregation, exciton lifetime, and interfacial charge transfer behavior govern energy‐conversion pathways.

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

Advanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...
