THE EFFECT OF CONCENTRATED LIGHT ON PHOTOCHEMICAL ENERGY CONVERSION BY NITROSYL CHLORIDE SOLUTIONS
Abstract
Experiments on the photolysis of nitrosyl chloride in CCl4 solution with unconcentrated sunlight showed that quantum yields and amount of energy stored with unconcentrated light were only 1/10 of that stored with concentrated light. Therefore, it has been shown that concentrated light considerably increases the output of a photochemical reaction. The results obtained with unconcentrated sunlight may be expressed in terms of the photodissociation of nitrosyl chloride and of the recombination of the photoproducts, NO and Cl. The pressure rise upon exposure to light rapidly approached a steady state. The location of the steady state was governed by the speed of the back reaction. Once the steady state is established, the gas is generated only as fast as it is consumed by the back reaction. On the other hand, if the gas were withdrawn continuously to feed a nitrosyl chloride fuel cell, the steady state would be upset and the gas would be generated at the rate at which it is generated in the approach to the steady state in our experiments.
