Abstract
Hydrogen peroxide (H2O2) was efficiently captured by co-crystallization with enantiomeric and racemic amino acids such as L-phenylalanine, DL-phenylalanine, and DL-asparagine in a dilute aqueous solution of H2O2 (30%) to unveil the requisites for efficient capturing of H2O2. In further dilute solutions of H2O2 (0.5–20%), L-Phe provided certain amounts of co-crystals with H2O2; however, co-crystals with H2O2 were hardly obtained for DL-Phe and DL-Asn. The efficient H2O2 capturing with L-Phe can be ascribed to its layered motif involving water molecules. The results obtained here would contribute to the development of an adsorbent that can efficiently capture H2O2 produced in environment-friendly H2O2-production systems such as photocatalytic systems.
