Scientists explore the strategies of defects and nanostructure fabrication for promoting piezocatalytic activity

As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. By using ubiquitous mechanical energy, piezocatalytic H2O2 evolution has been proven as a promising strategy, but its progress is hindered by unsatisfied energy conversion efficiency.
