Abstract

Semiconductor ternary metal oxides (TMOs) are ideal candidates as photoanode materials for the water oxidation reaction. The dynamics of photogenerated charge carriers dictates the efficiency of photoelectrocatalytic (PEC) systems depending on both internal (inside the photoactive material) and surface (mainly due to reaction kinetics) key issues. This paper presents recent results attained with up-to-date characterization tools to decouple bulk and surface charge recombination in relation to the synthetic strategies implemented to address PEC efficiency losses in TMO photoanodes, with particular focus on BiVO₄- and CuWO₄-based materials. Key aspects and the perspectives in the field are finally highlighted.

BiVO4和cuwo4基光阳极电荷载流子跟踪研究进展

半导体三元金属氧化物（TMOs）是水氧化反应的理想光阳极材料。光生载流子的动力学决定了光电催化（PEC）系统的效率，这取决于内部（光活性材料内部）和表面（主要是由于反应动力学）的关键问题。本文介绍了最新的表征工具所获得的最新结果，以解耦体积和表面电荷重组与合成策略的关系，以解决TMO光阳极的PEC效率损失，特别关注BiVO4和cuwo4基材料。最后强调了该领域的关键方面和前景。

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
