Photoproduction of Hydrogen in Polyvinylalcohol-Iimmobilized Spinach Chloroplsats with Platinum Catalysts
Polyvinylalcohol에 고정한 시금치 엽록체와 백금 촉매를 이용한 광수소 발생
Abstract
Photoproduction of hydrogen by free and polyvinylalcohol (PVA)-immobilized spinach chloroplasts was investigated. Immobilization of chloroplast with PVA increased the functional stability of the chloroplast during storage. PVA-immobilized chloroplasts preserved photosynthetic electron transport activity much better than free chloroplasts. The hydrogen production of free chloroplast decreased to 17% of initial activity after storage of six days. The hydrogen production of the PVA-immobilized chloroplast, however, showed 44% of initial activity after storage of 15 days. The maximal rate of hydrogen production was accomplished at 2
