Conjugated Polymer Nanomaterials for Solar Water Splitting

Exploration of robust and inexpensive photocatalysts for direct water splitting is highly desirable for solar energy utilization but remains a great challenge. Although some inorganic semiconductors have shown very promising activities, many suffer from low quantum efficiency and insufficient sunlight absorption or present environmental hazards. In recent years, conjugated polymer nanomaterials have rapidly become one of the most appealing candidates in photocatalysis, owing to their facile molecular functionalization, tunable optoelectronic properties, and good chemical stability. This essay highlights the recent advancement of conjugated polymer nanomaterials for solar water splitting. The research opportunities related to water photolysis together with the perspective and challenges in the field are discussed to inspire further exciting research in water splitting.
