Absolute thermodynamic efficiencies of conversion of light energy into chemical-free energy of molecular hydrogen by intact microalgae have been measured with an original physical measuring technique using a tin-oxide semiconducting gas sensor. Thin films of microalgae comprising of 5 to 20 cellular monolayers have been entrapped on filter paper, thereby constraining them in a well-defined circular geometry. Based on absolute light absorption of visible polychromatic illumination in the low-intensity region of the light saturation curve, conversion efficiencies of 6 to 24% have been obtained. These values are the highest ever measured for hydrogen evolution by green algae.
采用原始物理测量技术,利用氧化锡半导体气体传感器,测量了完整微藻将光能转化为分子氢化学自由能的绝对热力学效率。将包含 5 到 20 个细胞单层的微藻薄膜包埋在滤纸上,从而将其限制在一个明确定义的圆形几何形状中。基于可见光多色照明在光饱和曲线的低强度区域的绝对光吸收,得到了 6 到 24%的转换效率。这些值是迄今为止绿藻产氢所测到的最高值。
