▎ 摘  要

NOVELTY - Preparing hydrogen by performing piezoelectric catalytic cracking on water by using zinc and nitrogen co-doped graphene nano foam involves dispersing water and zinc and nitrogen co-doped graphene (ZnNG) nano foam to form turbid liquid, and adjusting the system atmosphere to a protective gas atmosphere. The mechanical energy is applied to the system to carry out water decomposition reaction under the condition of avoiding light, where ZnNG nano foam is zinc and nitrogen co-doped graphene nano foam and is formed by stacking and assembling two-dimensional zinc and nitrogen co-doped graphene nano sheets. USE - Method for preparing hydrogen by performing piezoelectric catalytic cracking on water by using zinc and nitrogen co-doped graphene nano foam. ADVANTAGE - The method enables to catalyze the water decomposition to prepare the hydrogen with high efficiency and environmental protection. The zinc and nitrogen co-doped graphene foam piezoelectric catalytic cracking prepare hydrogen method has excellent water decomposing rate, and recycle the mechanical energy such as noise, which widens the idea for environment protection.
