摘要: The highly flexible ZrO2/C nanofiber film was fabricated by electrospinning followed heat treatment of stabilization and carbonization. effects carbonization temperature on the morphology, microstructure, performance were investigated. As increases, tetragonal phase ZrO2 nanoparticles gradually transformed into monoclinic phase. a result, mechanical electrical properties improved. When reached 1100 °C, exhibited best flexibility with flexural modulus 6.24 ± 0.08 MPa, highest conductivity 476.5 S/m, promising electrocatalytic activity. These improvements can be ascribed to transition toughening effect nanoparticles, increase in oxygen vacancy concentration ZrO2, improvement graphitization carbon matrix. Hence, served as counter electrode for dye-sensitized solar cells, an efficiency 2.97% achieved.
