Charge‐Polarized Ni─S 4 Single‐Atom Sites Drive Selective Photoreforming of Poly(lactic acid) to Lactate and Hydrogen
Solar‐driven depolymerization of poly(lactic acid) (PLA) into its lactic acid monomer offers an attractive route to plastic recycling coupled with green hydrogen (H 2 ) production. However, simultaneously achieving high activity and product selectivity remains difficult because of inefficient charge utilization a...
