▎ 摘 要
NOVELTY - Preparation of benzaldehyde comprises placing benzyl alcohol, palladium decorated nitrogen-doped graphene material in reactor, adding distilled water, introducing oxygen and reacting at 80-140 degrees C for 4-8 hours. Weight ratio of benzyl alcohol and palladium decorated nitrogen-doped graphene material is 5-10:1. Content of palladium is 3-10%. USE - Method for preparing benzaldehyde (claimed). ADVANTAGE - The method is environment-friendly.
