Zinc vanadates have recently attracted attention as highly tunable metal oxides where optical, electronic, magnetic, and electrochemical functionalities can be combined into one system. Although much literature can be found on various zinc vanadate phases and their properties in various applications, there is a lack of comprehensive knowledge connecting synthesis parameters, structural features, defect generation, and functional properties.

Triboelectric nanogenerators (TENGs) are promising for harvesting low-frequency mechanical energy, yet their performance is often limited by the low charge density and modest dielectric properties of commonly used polymer triboelectric materials. Although metal−organic frameworks (MOFs)- based TENGs have been explored to enhance performance, most MOF-based TENGs use MOFs as filler materials, thereby restricting their intrinsic surface functionality and triboelectric nature. Herein, we ...
