Photochemical reactivity of zinc tetraphenylporphyrin induced by nonstoichiometric CdS nanoparticles in 2-propanol by Alex V. Isarov, John Chrysochoos

“…The photoreactivity of zinc tetraphenylporphyrin (ZnTPP) in the presence of photoexcited CdS nanoparticles and molecular oxygen in 2-propanol has been revisited. The photodecomposition of ZnTPP in 2-propanol, in the presence of CdS(e-CB/h+VB) and molecular oxygen, is linked to isopropyl free radicals formed by both hole transfer from CdS(h+VB) to (CH3)2CHOH and the reaction of superoxide ion (O2−) with 2-propanol. …”
