英文摘要： In the past decades carbonaceous nanomaterials synthesized via hydrothermal carbonization (HTC)process of biomass have been extensively studied and applications in many areas have been revealed such as drug delivery, energy storage, water purification , gas sensor and catalysis. Because of the active functional groups abundant in both the carbonaceous intermediates and as-prepared materials, metal or nonmetal additives could be easily interacted with the carbonaceous materials through convalent bond, ionic bond, coordination bond, hydrogen bond, etc. Following the theory this project mainly aims at the design, doping and modification of the carbonaceous materials during or after the HTC process.Different carbonaceous materials will be synthesized with certain morphology, structure and physical chemistry property. Then selective oxidation of alcohols will be carried out to evaluate the effect of these materials as catalyst supports. The difference between the carbonaceous materials will be investigated to show their impacts on metal immobilization and catalysis. Therefore development of novel carbonaceous materials based catalysts for alcohol oxidation, which are easy to prepare and excellent in activity and selectivity, could be expected. This project not only paves a way for construct efficient catalysts for al
