论文摘要
铁硫醇酸盐配合物是二氢酶酶的活性位点的简化模型。在这里，我们描述了这种贵金属无催化剂在水溶液中的实现，它在水溶液中作为光敏剂和三乙胺作为电子供体在一个专门设计用于研究H2光生产研究的实验台中。板凳由可调节的可见光源，设备齐全的扁平圆环光反应器和分析设备组成。通过准确测量压力增加，获得了不同实验条件下H2产生的速率。已经进行了主要吸收的源蓝色光子的光谱辐射分析。结果证明了H2产生的速率与吸收的辐射光的平均体积速率成正比，该辐射光率显示了线性热动力学偶联。生物启发的催化剂已被证明是无限制的，并揭示了未来大规模H2生产的有趣功能。
The iron thiolate complex is a simplified model of the active site of diiron hydrogenase enzymes. Here, we describe the implementation of this noble metal free catalyst in aqueous solutions using eosin Y as photosensitizer and triethylamine as an electron donor in an experimental bench specially designed for the study of H2 photoproduction. The bench is composed of an adjustable visible light source, a fully equipped flat torus photoreactor and analytical devices. Rates of H2 production under varied experimental conditions were obtained from an accurate measurement of pressure increase. A spectral radiative analysis involving blue photons of the source primarily absorbed has been carried out. Results have proven the rate of H2 production is proportional to the mean volumetric rate of radiant light absorbed demonstrating a linear thermokinetic coupling. The bio-inspired catalyst has proven non-limiting and reveals interesting capabilities for future large scale H2 production.
