Reaction mechanism of surfactant-sensitized chemiluminescence of bis(2,4,6-trichlorophyenyl) oxalate and hydrogen peroxide induced by gold nanoparticles

The chemiluminescence (CL) of bis(2,4,6-trichlorophyenyl) oxalate with hydrogen peroxide in the present of cationic surfactant and gold nanoparticles was studied. The CL emission was obviously enhanced in the presence of surfactant at a suitable concentration, with a synergetic catalysis effect exhibited. Different sizes of gold nanoparticles (115 and 50 nm) showed different effects on CL intensity. Mechanisms of the CL reaction and sensitization effect are discussed.
