Photocatalytic performance of BiPO4 nanorods adjusted via defects
The effect of defect on the photocatalytic and photoelectric performance of BiPO4 has been revealed. The bulk defects of BiPO4 such as bismuth vacancies (VBi), oxygen vacancies (VO) and so on were formed during the ball-milling process. These bulk defects of BiPO4 inhibited the separation of photo-generated charges greatly and thus reduced photocatalytic activity. Most of the bulk defects were repaired and the photocatalytic activity of BiPO4 was also recovered mostly via calcination and reflux. Reflux could repair the bulk defects of BiPO4 much better than calcination. The mechanism of the photocatalytic degradation of pollutants over BiPO4 was not changed by defects, and the main oxidation active species of BiPO4 is photo-generated hole.
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.
