Tuning piezoelectric field for optimizing the coupling effect of piezo-photocatalysis
In this work, the tuning of piezoelectric and energy-harvesting are realized in solvothermal synthesized Cl doped ZnO nanorods (NRs), which is designed to boost the coupling effect of piezo-photocatalysis for dye decomposition. For the optimal sample 5%-Cl-ZnO, the coupling constant is about 24.4 times greater than that of pure ZnO, which is benefited from the synergistic effect of the increased radial piezoelectric properties and the superiority of nanorods structure. Optimal 5%-Cl-ZnO NRs not only maintains high migration efficiency for photo-generated carriers in the axial direction, but also separate more thoroughly and transmit faster in the radial direction. This work clearly demonstrates a high correlation between piezoelectricity and coupling effect of piezo-photocatalysis, and provides a new strategy for optimizing the transport of photogenerated carriers in 1D photocatalyst.
期刊介绍：
Applied Catalysis B: Environment and Energy (formerly Applied Catalysis B: Environmental) is a journal that focuses on the transition towards cleaner and more sustainable energy sources. The journal's publications cover a wide range of topics, including:
1.Catalytic elimination of environmental pollutants such as nitrogen oxides, carbon monoxide, sulfur compounds, chlorinated and other organic compounds, and soot emitted from stationary or mobile sources.
2.Basic understanding of catalysts used in environmental pollution abatement, particularly in industrial processes.
3.All aspects of preparation, characterization, activation, deactivation, and regeneration of novel and commercially applicable environmental catalysts.
4.New catalytic routes and processes for the production of clean energy, such as hydrogen generation via catalytic fuel processing, and new catalysts and electrocatalysts for fuel cells.
5.Catalytic reactions that convert wastes into useful products.
6.Clean manufacturing techniques that replace toxic chemicals with environmentally friendly catalysts.
7.Scientific aspects of photocatalytic processes and a basic understanding of photocatalysts as applied to environmental problems.
8.New catalytic combustion technologies and catalysts.
9.New catalytic non-enzymatic transformations of biomass components.
The journal is abstracted and indexed in API Abstracts, Research Alert, Chemical Abstracts, Web of Science, Theoretical Chemical Engineering Abstracts, Engineering, Technology & Applied Sciences, and others.
