description | [Image: see text] In this work, the study of photocatalytic hydrogen production by RGO/ZnIn(2)S(4) with simultaneous degradation of organic amines was carried out in the presence of organic amines in wastewater as the sacrificial agents. The effects of several factors, such as organic amine types, pH value, catalyst concentration, organic amine concentration, and sunlight source, on the photocatalytic activity of RGO/ZnIn(2)S(4) for H(2) production were investigated. At the same time, its performance of degrading organic amines during H(2) production was also examined. The results showed that the order of H(2) production activity of RGO/ZnIn(2)S(4) in six organic amine solutions was N(CH(2)CH(3))(3) > N(HOCH(2)CH(2))(3) > N(CH(3))(3) > HO(CH(2))(2)NH(2) > C(6)H(5)–N(2)> CO(NH(2))(2), and the highest H(2) production was in N(CH(2)CH(3))(3) (triethylamine) solution, being 1597 μmol·g(–1)·h(–1), which is 2.6 times as high as that using the aqueous solution mixture of Na(2)S and Na(2)SO(3) as the sacrificial agent. In addition, when the pH was 13, the catalyst concentration was 1.0 g·L(–1), and the triethylamine concentration was 1.0 mol·L(–1), the photocatalytic activity was the highest. Furthermore, the relationship between triethylamine concentration and H(2) production was analyzed according to the theory of dynamics. |
