X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Broadband tunable nanostructures for surface-enhanced infrared absorption spectroscopy
Optics ExpressSurface-enhanced infrared absorption (SEIRA) spectroscopy leverages nanostructures to enhance the infrared absorption spectrum. Nanorods with different lengths yield different plasmon resonance wavelengths conducive to broadband SEIRA. Here, we systematically investigated the far-field and near-field behaviors of the nanostructures composed of one to ...
