Recently, the research team of Wang Feng of the Bioenergy Chemicals Research Group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences used photocatalytic methods to achieve the cracking of biomass polyols to prepare methanol and syngas under mild conditions, which provided new ideas
for biomass conversion and utilization.
The team discovered a method
for photocatalyzing biomass to prepare methanol and syngas at room temperature.
Under the condition of ultraviolet light excitation, copper supported by titanium dioxide nanorods is used as a photocatalyst, andC2-C6 polyols and carbohydrate molecules are used to generate methanol and syngas
at room temperature.
The gas phase products are mainly CO and CO2, and the ratio of CO/CO2 can be adjusted through the energy level structure, surface defects and solvent system regulation of the catalyst, and the CO selectivity can reach 90%.
