Indium Clusters With 6s2 Lone‐Pair Effect as Excitonic Electron Reservoirs for Direct 2e− Photocatalytic H2O2 Photosynthesis

open access: yesAngewandte Chemie, EarlyView.
This study demonstrates that indium clusters with 6s2 lone‐pair effect anchored on carbon nitride act as excitonic electron reservoirs to boost charge separation and O2 activation for highly selective direct 2e− oxygen reduction. This work establishes cluster‐mediated electron reservoir engineering as a general strategy for enhancing selective ...

Surface‐Engineered Ti3C2Tx MXene/Cu2O Photocathodes for Highly Selective Photoelectrocatalytic CO2 Reduction to Ethanol

open access: yesAdvanced Energy Materials, EarlyView.
Surface‐engineering Ti3C2Tx MXenes with an in situ‐grown TiO2 layer on the surface in combination with visible‐light‐absorbing Cu2O significantly enhances charge separation and carrier extraction while improving Cu2O resistance to photocorrosion. The resulting Cu2O/TiO2‐MXene photocathodes enable highly selective, solar‐driven ethanol production ...

Molecularly Templated Buried Interfaces for Inverted Perovskite Solar Cells

open access: yesAngewandte Chemie, EarlyView.
We demonstrate a molecularly matched buried interface between SAM and perovskite, enhancing adhesion and passivating defects. This optimized interface achieves 26.58% power conversion efficiency and 86.72% fill factor with exceptional operational stability in both large‐area and wide‐bandgap devices, thereby increasing efficiency and prolonging ...

Holistic Top‐to‐Bottom Film Restructuring to Achieve Highly Stable Unencapsulated Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A novel top‐to‐bottom film restructuring strategy is applied to perovskite films, taking advantage of high penetration of vapor‐phase ligand. A gradient‐distributed 2D perovskite structure is built up from top surface to film bulk, meanwhile, inhomogeneity at the buried interface is mitigated, which leads to high quality perovskite films with improved ...

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

open access: yesAngewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

open access: yesAdvanced Intelligent Discovery, EarlyView.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

Grenzflächen‐Synergie zwischen Mn und Kohlenstoffnitrid ermöglicht die selektive photokatalytische C–H‐Chlorierung mittels Einzelatomkatalyse

open access: yesAngewandte Chemie, EarlyView.
Ein Mangan‐Einzelatom‐Photokatalysator auf funktionalisiertem Kohlenstoffnitrid ermöglicht die selektive, durch sichtbares Licht angetriebene C(sp2)–H‐Chlorierung. DFT‐gestützte mechanistische Untersuchungen zeigen, dass die photoinduzierte Ladungstrennung NCS aktiviert, während isolierte Mn‐Zentren Mn–Cl‐Intermediate an der Katalysatorgrenzfläche ...
