摘要：

Hitting water with nanotrees: A three-dimensional branched heterojunction array for water oxidation based on cobalt-doped α-Fe2O 3 nanorod cores and MgFe2O4 shells has been synthesized. Such an architecture not only has a large surface area and excellent light absorption properties, and shows fast charge transport, but also exhibits a very high photoelectrochemical activity for water oxidation and a high stability.
