Synergistic Fluorine and Cyanide Co‐Modification to Reinforce Photoinduced Excitons Formation and Transfer for Efficient CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

open access: yesAdvanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.
