This work is a preliminary assessment of comparative piezoelectric efficacy influenced by changes in synthesis, effecting dimension and particle size. Advantages of hydrothermal, molten salt, and solvothermal synthesis methods were leveraged to facilitate several chemical and surface engineering techniques to enhance piezoelectric properties by increasing the surface area of zinc stannate nanoparticles. The combination of these treatments reduce the size of zinc stannate to approximately ∼40nm-80nm weblike networks. Scanning electron microscopy (SEM) and X-Ray Diffraction (XRD) analysis reveal a mesoporous protonated tristannate (H<sub>2</sub>Sn<sub>3</sub>O<sub>7</sub>) nanoweb template with connecting wirelike strands having diameters ranging from 12-27nm across and pores up to 50nm in diameter.
