摘要：

Photocatalytic fillings for cavities: A very simple, yet highly efficient method to introduce triphenylpyrylium (TPP) ions into Y-zeolite cavities has been found (see picture). It consists of simply stirring the non-activated NaY-zeolite with an aqueous solution of triphenylpyrylium hydrogen sulfate at 40°C, before drying the doped support. The FTIR and elemental analyses of the product (TPP-Y), as well as the repeated and reproducible photocata. lytic reactivity of the TPP-Y confirm the presence of the TPP+ electron acceptor inside the cavities of the support.
