The backbone/branch
structure shows a better
performance than the
core-shell structure due to
its increased surface area.

A tree-like (trunk: Zn, bark:
TiO
2
, branches: CuO)
hierarchical structure
developed with a full
solution-processable
strategy and its application
as a photoanode for water
splitting has been
demonstrated. The CuO
branches absorb visible
light, and the TiO
2
shell
protects the ZnO trunk
from erosion and gathers
UV light simultaneously to
generate photoelectrons,
while the ZnO nanowire
works as an e
cient
pathway for charge
transport.
