ZnO nanonails: Organometallic synthesis, self-assembly and enhanced hydrogen gas production

We report the rational synthesis and characterizations of defect-rich zinc oxide (ZnO) nanonails that were prepared by organometallic approach and their implementation as an efficient photocatalyst for hydrogen (H2) generation. The ZnO nanonails were prepared from zinc stearate in n-octadecene that...
