Plasmonic TiN-supported CuPd alloy for highly selective and base-free photocatalytic Glaser homocoupling

An ice-templated CuPd/TiN catalyst is reported for efficient, base-free photocatalytic Glaser homocoupling. Synergizing TiN's LSPR effect with CuPd alloying, the system achieves 99% conversion and 100% selectivity. XAS-confirmed electron transfer from Cu to Pd facilitates superoxide radical generation, providing a robust and sustainable strategy for green C-C coupling.
