• • Piezoelectric-coupled photoelectrocatalysis enhances electron-hole pair separation efficiency, leading to improved degradation rates of organic pollutants; specific degradation rates are referenced in Section B, e.g., 4-chlorophenol degradation via piezo-dechlorination.
• • The technology converts mechanical energy into electrochemical energy, enabling reactions such as water splitting, CO2 reduction, and pollutant decontamination, with potential for high energy conversion efficiency.
• • Integration of piezoelectric effect with photocatalysis addresses bottlenecks like limited light absorption and carrier recombination, potentially increasing solar energy utilization efficiency.
• • Challenges include short electrode lifetimes and low energy efficiency in electrochemical methods; piezoelectric coupling offers a pathway to mitigate these issues by reducing external energy input.
