Description
Technical Field
The invention belongs to the technical field of photo-acoustic concerted catalysis, and particularly relates to preparation and application of a chlorine-doped zinc oxide nanorod.
Background
The contemporary world is facing environmental pollution due to rapid global industrialization leading to deterioration of water, air and soil quality due to accumulated organic and inorganic toxic compounds. These toxic compounds have hazardous properties that affect the ecosystem and thus human health. For this reason, remediation of contaminated water, air and soil is essential to improve human survival. Among various environmental remediation methods, the degradation of contaminants by photocatalytic semiconductor materials has been considered as a promising green technology for environmental remediation.
During the photocatalytic reaction, the host of photon-generated carriers is only two types: the complex conversion is thermal and other ineffective energy sources or participates in surface reaction, and the latter is an ideal energy conversion mode. Only when the photo-generated carriers smoothly migrate to the surface of the catalyst and act with the electron donor (acceptor) adsorbed on the surface of the catalyst, the ideal photo-catalytic oxidation (reduction) reaction can occur. In the above process, the separation and migration process of the photon-generated carriers is an intermediate link connecting the semiconductor light excitation and the surface reaction behavior. The improvement of the carrier separation efficiency of the semiconductor catalyst and the acceleration of the interface charge transfer are key scientific problems to be solved for constructing high-efficiency photocatalytic materials and are also the research frontier in the current international photocatalytic field.
Recently, attention has been focused on the use of ferroelectric and piezoelectric materials in photocatalytic technology. When a piezoelectric material is used, the built-in electric field generated by the piezoelectric material under force helps the charge separation. In the photocatalysis and piezoelectric composite materials reported at home and abroad, zinc oxide is widely reported as a star material, but the catalytic efficiency of the zinc oxide needs to be improved, the preparation process is complex, the yield is low, and the industrial production requirements cannot be met.
The invention discloses a new material with better piezoelectric property, which can promote the degradation of photocatalytic dye under the simultaneous action of sound wave and light, and the performance of the new material for catalyzing and degrading polluted wastewater is obviously superior to the action of zinc oxide by independent light or independent sound wave. The material can realize double capture of light energy and mechanical energy, and carry out polluted wastewater degradation under the synergistic drive of sound waves and light waves.
