General Description

The chemical compound [(sulfonatoperoxy)sulfonyl]oxidanide, also known as Caro's acid, is a peroxymonosulfate compound with the chemical formula HSO??. It is a white, water-soluble solid that is widely used as an oxidizing agent in various industrial and laboratory processes. Caro's acid is a powerful oxidant that can be used for the synthesis of organic compounds, as well as for the treatment of water and wastewater. It is also used in the production of paper and textiles, as well as in the cleaning and disinfection of surfaces. However, it should be handled with caution due to its potential for causing skin and eye irritation, as well as its ability to react violently with certain organic compounds.

Photoelectrochemical reaction for the efficient production of hydrogen and high-value-added oxidation reagents

A porous and thick photoelectrode of WO3 in the monoclinic phase was prepared to realize the recovery of H2 and high-value-added oxidation reagents with efficient solar energy conversion. The WO3 photoelectrode enabled the efficient production and accumulation of O2, S2O82-, Ce4+, and IO4- as oxidation products. Most notably, S2O82-, which possesses the highest oxidizability among all the peroxides, was generated with high applied bias photon-to-current efficiency (2.2 %) and faraday efficiency (≈100 %) upon irradiation from the back side of the photoelectrode. The design of a tandem photoelectrode system combining a dye-sensitized solar cell (DSSC) was also challenged for the realization of this photoelectrode system without external bias. A high solar energy conversion efficiency (5.2 %) was achieved in the tandem system comprising the WO3 photoelectrode connected to two DSSCs with a near-IR-utilizing dye in series for the production of H2 and S2O82-.
