The mechanochemical (MC)

Electron/hole piezocatalysis in chemical reactions

“…15 Another is La-modified lead zirconate titanate (PLZT) which can be produced by planetary ball milling of PbO and titanium dioxide (TiO 2 ). 16 Due to the toxicity of lead, there is a pressing need to develop environmentally benign lead-free piezoelectric materials. 17,18…”

“…Incorporation of conductive particles into the polymeric matrices is also suggested for improvement of the dielectric permittivity of composites. [15][16][17][18][19][20][21][22] For instance, in a three-phase PA11/PZT/CNT composite, a synergistic effect was observed between PZT particles used as piezoelectric fillers and the CNT selected as a conductive filler. 110 In another study, a ternary nanocomposite of PVDF/BaTiO 3 /CNT was prepared based on the homogeneous dispersion of BaTiO 3 and CNT fillers in the PVDF matrix.…”

“…147 BM is a clean, green, and simple technique that has received increasing attention due to its wide applications in environmentally benign and non-thermal solid-state reactions. 16 The other advantages of BM can include no use or negligible use of solvent and the use of incompatible and immiscible reagents. 148 Under the continual impact, compression, shearing, and friction of BM, the solid reactants experience irreversible distortion and produce new active sites, providing more contact to react.…”
