论文摘要
本文致力于介绍新型实验台，旨在研究H2的光生生产。它由三个主要部分组成：光源，设备齐全的平圆环反应器和相关的分析系统。反应堆流体动力行为已仔细检查，可以被认为是完美混合的。得益于对帐量子传感器和放肌的实验，光子通量密度是准确的。入射的光子方向垂直于反应堆窗口。在这种配置中，辐射传输描述可以正确近似为笛卡尔几何形状中的一个维度问题。基于气体紧密光反应器的准确压力测量，H2的生产速率（使用与硫化物和亚硫酸盐离子作为孔清除剂相关的CDS颗粒）易于获得且可信赖。事实证明，明显量子产率的首次估计取决于吸收辐射光能的平均体积速率，因此表明需要使用辐射转移方法来了解观察到的现象以及适当的热运动偶联。
This article is dedicated to the presentation of a novel experimental bench designed to study the photoproduction of H2. It is composed of three main parts: a light source, a fully equipped flat torus reactor and the related analytical system. The reactor hydrodynamic behaviour has been carefully examined and it can be considered as perfectly mixed. The photon flux density is accurately known thanks to reconciled quantum sensor and actinometry experiments. The incident photon direction is perpendicular to the reactor windows; in such a configuration the radiative transfer description may be properly approximated as a one dimensional problem in Cartesian geometry. Based on accurate pressure measurement in the gas tight photoreactor, the production rates of H2 (using CdS particles in association with sulphide and sulfite ions as hole scavengers) are easily and trustingly obtained. First estimations of apparent quantum yield have proven to be dependent on mean volumetric rate of radiant light energy absorbed hence demonstrating the need for the use of a radiative transfer approach to understand the observed phenomena and for the proper formulation of the thermo-kinetic coupling.
