elective production of hydrogen peroxide and oxidation of hydrogen sulfide in an unbiased solar photoelectrochemical cell

Identifying cost-effective processes for use of solar energy is challenging. Production solely of low-value fuels such as hydrogen necessitates extremely low capital cost systems that have been yet to be identified. Demonstrating a dual-function solar-to-chemical process making higher value chemicals from photogenerated electrons and consuming negative value waste products with the holes can significantly improve the economic sustainability of the process. In this work, we demonstrate a combined photoelectrochemical cell for the remediation of toxic hydrogen sulfide (H2S) and the production of valuable hydrogen peroxide (H2O2). Moreover, we highlight the importance of fine-tuning the selectivity of photochemical reactions by using well-designed transformation processes.(2014, DOI: 10.1039/c4ee01503g)。
