摘要

The natural environment is being threatened by the buildup of many toxins in the abiotic components such as air, soil, and water. Today, there is an urgent need to clean up environment from degradation and deterioration from the natural resources. Half of the world’s population, according to the World Health Organization (WHO), would reside in water-stressed areas by 2025. Furthermore, 22% of healthcare institutions in the least developed nations lack waste managementManagement services, 21% lack sanitation services, and 22% lack water services. Recently, a novel idea was presented that improved the separation of photoinduced charge carriers by taking advantage of the inherent electric field created by ferroelectric, pyroelectric, and piezoelectric phenomena in photocatalytic particles. The use of piezoelectric materials were attarcting environmental pollutatnt cleanup as one of the activity of photodegradation and it has gained significant attention by researhcers to investigate novel systems to mitigate the environmental issues. Since the dipole polarization creates an inherent electric field, the non-centrosymmetric character of the materials leads to the unique catalytic properties of the piezoelectric materials. The latter acts as a catalyst to move the light-induced charge transporters, allowing for their split-up. This chapter illustrates the application of piezoelectric elements to environmental remediation through photocatalysis and catalysis, particularly piezoelectric-catalysis. The principles and fundamental characteristics of pyroelectric, ferroelectric, and piezoelectric resources are covered in detail in this study. It is a need of hour study to explore the state of the art in the field’s research and potential applications using piezocatalysis, and piezophotocatalysis are examined as a potential tool to safeguard nature problems.
