“…[14,15]. However, in the presence of ZnS particles, hydrogen can be generated with the wavelength around 350nm [6,16,17]. This suggested that the ZnS extended the useful range of the light from 290 to 350 nm.…”

Repulsive force generation due to topological effect of circulating magnetic fluids AIP Conf.Abstract. For the effective hydrogen generation from H2S, it should be compatible that the increscent of the photocatalytic (or electrochemical) activities and the development of effective utilization method of by-products (poly sulfide ion). In this study, "system integration" to construct the sulfur cycle system, which is compatible with the increscent of the hydrogen and or electron energy generation ratio and resource circulation, is investigated. Photocatalytic hydrogen generation rate can be enhanced by using stratified photocatalysts. Photo excited electron can be transpired to electrode to convert the electron energy to hydrogen energy. Poly sulfide ion as the by-products can be transferred into elemental sulfur and/or industrial materials such as rubber. Moreover, elemental sulfur can be transferred into H2S which is the original materials for hydrogen generation. By using this "system integration", the sulfur cycle system for the new energy generation can be constructed.

“…To make more efficient use of solution with mixed sulfide and sulfite for photocatalytic hydrogen evolution, Grätzel et al further propose the concept "thiosulfate cycle" [36]. Under light illumination, S 2 O 3 2-could be disproportionated into S 2-and SO 3 2-with the assistance of TiO 2 (see specific reaction in Eqs.…”

Hydroμen sulλide is an extremely toxic μas which is μenerated λrom both nature λactors and human λactors. " proper method λor the eλλicient decomposition oλ hydroμen is oλ μreat importance. Usinμ traditional Claus process, hydroμen sulλide could be decomposed into hydroμen oxide and sulλur. One drawback oλ this process is that the enerμy stored in hydroμen sulλide is partially wasted by the λormation oλ hydroμen oxide. In λact, the enerμy could be utilized λor the μeneration oλ hydroμen, a potential enerμy source in λuture, or other chemical products. Various methods that could possibly make better use oλ hydroμen sulλide have been studied in recent years, like thermal decomposition, plasma method, electrochemical method, and photochemical method. In particular, there have been hiμh hopes in photochemical method due to the possible direct solar enerμy conversion into chemical enerμy. Unlike traditional photocatalytic water splittinμ, hydroμen sulλide decomposition is more accessible λrom the thermodynamic point oλ view. Photocatalytic hydroμen sulλide decomposition could occur in both μas phase and solution phase and various systems have been reported. "esides, the photoelectrochemical decomposition oλ hydroμen sulλide is also hiμhliμhted. In this chapter, we will simply introduce the current situation λor photochemical decomposition oλ hydroμen sulλide.
