Abstract
This review summarizes the investigation of semiconductor nanoheterostructures (NHSs) aimed at enhancing the efficiency of solar fuel generation through various time-resolved spectroscopic techniques, including transient absorption spectroscopy (TAS), time-resolved photoluminescence, and in situ TAS. These time-resolved spectroscopies provide insights into the mechanisms of exciton and charge carrier dynamics at the heterojunctions of optimized semiconductor NHSs. The significance of these techniques underscores the necessity for designing effective photocatalysts and photoelectrodes for applications in photocatalytic water splitting and carbon dioxide reduction. Finally, the current challenges and future directions for studying charge carrier dynamics in semiconductor NHSs for photocatalytic solar fuel generation are outlined and discussed.
期刊介绍：
Advanced Energy and Sustainability Research is an open access academic journal that focuses on publishing high-quality peer-reviewed research articles in the areas of energy harvesting, conversion, storage, distribution, applications, ecology, climate change, water and environmental sciences, and related societal impacts.
