Zn shows an oxidation state of +2.
The phenol gets converted into phenoxide ion and proton thus released accepts an electron from Zn forming H radical.
Also because of the heating there is homolytic fission of C of phenyl ring and O-
The O- thus formed accepts an electron from Zn and forms oxide ion.
In this way zinc forms zinc oxide and phenyl radical thus produced forms a bond with H radical.
