The application discloses a method for preparing hydrogen by using hydroquinone as raw material. The method comprises the following steps: uniformly mixing hydroquinone, a catalyst and water, and then heating and reacting under a non-active gas atmosphere to obtain a product containing hydrogen. The yield of hydrogen can reach 83.8 mmol. The hydroquinone is one of main pollutants in phenolic wastewater. The conversion of the hydroquinone into hydrogen by catalysis is beneficial to the resource utilization of the phenolic wastewater, and the process has high treatment efficiency and is environment-friendly. From the perspectives of waste utilization and clean energy development, the process has important academic significance and potential application prospect.
