Design strategies and effect comparisons toward efficient piezocatalytic system

Efficient conversion of mechanical energy via piezocatalysis behaves great potential on relieving energy crisis and environmental deterioration, and functioning for sterilization, disease therapy, personal cleaning, organic synthesis, biomass conversion, etc. However, the unsatisfactory energy transformation efficiency tremendously blocks practical applications of piezocatalysis, which inspires the appearance of plentiful strategies to elevate piezocatalytic activity. Even so, the selection of proper design strategies in specific piezocatalytic application is still vague and challenging. This review concentrates on the recent progresses on the design tactics applicable to excellent piezocatalytic system fabrication and the effect contrast to uncover their applied potential. It begins with the fundamentals and principles of piezocatalysis, including its mechanisms, requirements, and developments. Next, the currently adopted strategies throughout the whole piezocatalysis process are divided and introduced detailedly. In particular, highlighted is the comparison of promotion effect triggered by diverse strategies to select out more efficient design methods for piezocatalytic system in different application areas. Finally, the facing challenges and promising development directions of superb piezocatalytic system creation are presented, which would hopefully stimulate rational design and accelerated birth of more exceptional piezocatalytic systems serviceable for numerous application fields.
