High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

One‐End‐Truncated Au52 and Au70 Quantum Rods: High‐Quantum‐Yield NIR‐II Emitters With Aspect‐Ratio‐Dominated Photophysics

Angewandte Chemie, EarlyView.
Two nanoclusters, Au52(PET)38 and Au70(PET)50, where PET = 2‐phenylethanethiolate, are isolated, which constitute a series of one‐end‐truncated kernel topologies. Both Au52 and Au70 exhibit NIR‐II absorption at 1032 and 1275 nm and nanosecond fluorescence at 1100 and 1360 nm, respectively, with high quantum yields (20.9% for Au52 and 14.8% for Au70 ...
