摘要
以半导体材料 (Zn·Cd)S :Ag KI为催化剂 ,在单色 (红 )光光照下 ,成功地模拟了光合作用的光合磷酸化 ,研究了红光的光照度、照光时间、二磷酸腺苷 (ADP)浓度及催化剂量等对三磷酸腺苷 (ATP)合成的影响。最佳条件为 :光照度 30 2 2Lx ,照光时间 1h ,半导体粉量 2 5 0mg ,Na2 HPO42 0mmol/L ,MgCl2 3.1mmol/L ,K3 Fe(CN) 62 .0mmol/L ,ADP浓度为 0 1mmol/L ,转化率平均可达到 3 6 %。
Using inorganic semicondutor(Zn·Cd)S:Ag KI as catalyst,the photophosphorylation of photosynthesis is successfully mimicked with the monochromatic (red) light. The effect of the intensity and time of red light illumination,the concentration of adenosine diphosphate(ADP) and quantity of catalyst on the yield of adenosine triphosphate are studied. The optimum conditions are as below:illumination intensity 302.2 Lx,illumination time 1 h,semiconductor powder amount 25.0 mg,the concentration of Na 2HPO 4 2.0 mmol/L,MgCl 2 3.1 mmol/L,K 3Fe(CN) 6 2.0 mmol/L,ADP 0.1 mmol/L.The average conversion ratio reached 3.6% under the optimal condition.
