This research presents a promisingfacile method to embed lead toxicity reduced inorganic perovskite quantum dots (IPQDs CsPb0.25Zn0.75I3) with eco-friendly cellulose nanocrystal (CNC) ligands into polyvinylidene fluoride (PVDF) electrospun nanofibers for high-performance piezoelectric device (PPNG). We investigate the effects of CNC ligands on the formation of PVDF β-crystalline phasealso analyzed the improved crystal stability of the IPQDs, forming the basis for highly efficientdurable PPNG in piezoelectronics. Furthermore, IPQDs semiconductor with exceptional properties of such as broad light absorption range from visible to near-infrared region is set to be next-generation pyrocatalytic applications front-runners.

The intrinsic advantages of piezoelectric materials warrant that the novel technology would not only enhance the utilization of pressure sensor but also inspire novel technological adaptation into other renewable energy processes. To date, many researches have been carried out on PVDF to improve the output power. Doping of optically activestable eco-friendly filler in PVDF nanofiber may enable the development of the next-generation flexiblewearable piezoelectric devices. However, the limited studies volume on perovskite quantum dot incorporation into nanofiberstheir photophysical effects in this field need to be addressed.

Electrospinning is a widely employed industrial nanofibers fabrication method at a low-cost. Simultaneously, environmentally friendly cellulose nanocrystals,PVDF are materials commonly found in industrial-based application. An environmentally-friendly approach is employed herein to enhance perovskite stability. The novel material possesses hydrophobic, piezoelectricpyrocatalytic properties for use in energy harvester device for real-time charging. The hydrophobic flexible nanofiber-based pyrocatalyst not only has high-sensitivity detection characteristics, fast charging abilitylong-term storage ability, but also can be become the main driving force for energy harvesters in the future.
