title: Phosphate Ion Functionalized Co3O4Ultrathin Nanosheets with Greatly Improved Surface Reactivity for High Performance Pseudocapacitors.
abstract: A surface-modified Co3O4ultrathin nanosheet (denoted as PCO) is reported via controllable phosphate ion functionalization for pseudocapacitors. An energy density of 71.6 W h kg-1(at 1500 W kg-1) is achieved by the PCO-based pseudocapacitor. The unique porous nanosheet morphology, high surface reactivity, and fast electrode kinetics of PCO are found to be responsible for the enhanced pseudocapacitive performance.
