Abstract In this research, a unique strategy was developed to enhance the output performance of 2D ZnO nanosheets based piezoelectric nanogenerator (PENG). The Br doped 2D ZnO nanosheets were fabricated by facile hydrothermal method on nanoporous anodic aluminum oxide (AAO) template. Along with structural and optical characterization of Br doped 2D ZnO nanosheets, the electrical output performance of Br doped 2D ZnO PENG was demonstrated under external mechanical force. The corresponding output voltage of Br doped 2D ZnO nanosheets PENG reached to 8.82 V at 6HZ, which is 3 times higher than undoped ZnO nanosheets PENG. The output power density of Br doped 2D ZnO nanosheets PENG reached to 38.8962μWcm−2 at an external load resistanec of about 2 MΩ. The Br doping in ZnO nanosheets significantly increased the sensitivity of PENG for pressure sensing and the flexibility of PENG contribute in the application of position sensing.

摘要 在这项研究中，开发了一种独特的策略来提高基于二维 ZnO 纳米片的压电纳米发电机 (PENG) 的输出性能。在纳米多孔阳极氧化铝 (AAO) 模板上，通过简便的水热法制备了 Br 掺杂的二维 ZnO 纳米片。随着 Br 掺杂的二维 ZnO 纳米片的结构和光学表征，Br 掺杂的 2D ZnO PENG 在外部机械力下的电输出性能得到了证明。Br掺杂的二维ZnO纳米片PENG的相应输出电压在6HZ时达到8.82 V，是未掺杂的ZnO纳米片PENG的3倍。在约 2 MΩ 的外部负载电阻下，Br 掺杂的二维 ZnO 纳米片 PENG 的输出功率密度达到 38.8962μWcm-2。
