nanowires samples using alkanedithiol groups with different alkyl chain length were tested for
hydrogen production. 1, 3-PDT exhibits the highest hydrogen production rate as 7288 ± 204 umol/h/g, which is 4 and
63 times higher than 1, 4-BDT and 1, 12-DDT respectively. The distance between photogenerated sites on Zn3
P2
nanowires
and top molecule of alkanedithiol groups affects hydrogen reduction activity. Hydrogen production rate depends on
electron transfer rate and tunneling rate. Mechanism explained gives a comprehensive perspective on how to optimize the
structure of the Zn3
P2
nanowires and maximize the hydrogen reduction activity
