Integrated Experiment Design for Optimized Preparation and Piezocatalysis Performance Analysis of BaTiO3
In order to organically combine the latest water treatment technique,large-scale instrument analysis and operation capability cultivation,a novel integrated experiment for the optimized preparation and piezocatalysis performance analysis of BaTiO3 is systematically designed.The piezocatalytic performance of BaTiO3 nanomaterial on the dye degradation is effectively optimized by heat treatment.The generation of free radicals during the degradation process is analyzed by electron spin resonance(ESR)technique,and the role of different radicals in the dye degradation is confirmed by quenching experiment.The results show that 2 hours heat treatment of BaTiO3 can effectively improve the performance of the piezoelectric catalytic degradation of RhB dyes.The hydroxyl radical,singlet oxygen and superoxide radical are detected by ESR during the degradation process.The quenching experiments results show that hydroxyl radical plays a leading role in the process of dye degradation.
