Abstract
In recent years, environmental problems such as global warming and energy saving technologies have attracted considerable attention. Hydrogen has been recognized as a clean and efficient energy carrier and as the significant chemical in petrochemical production. Photocatalytic water splitting is an expected chemical process for hydrogen production because of its environmental–friendly nature and its potential for low–cost. The technology of photocatalytic water splitting ranges from development of photocatalyst to purification of hydrogen. A surface–modified CHA zeolite membrane with higher selectivity of H2/N2 (N2 is analogous gas to O2) was prepared to be utilized in hydrogen separation in an artificial photosynthesis process.
