Preparation method and application of carbon quantum dot/metal organic skeleton catalyst

The invention belongs to the field of new energy resources and particularly relates to a method for compounding a carbon quantum dot with a metal organic skeleton material. A catalyst prepared by virtue of the method is applied to the reduction preparation of CO through photocatalysis of CO2. For solving the problem that the activity of CO2 obtained through photocatalytic reduction of a single metal organic skeleton at present is low, an aminated metal organic skeleton material and the carbon quantum dot with carboxylic acid are combined to obtain a catalyst, and the obtained catalyst is usedfor preparing CO from CO2 through high-efficiency photocatalytic reduction. The catalyst can simultaneously have the advantages of the metal organic skeleton and the carbon quantum dot and further hasvery high photocatalytic reaction activity due to the synergistic effect of the metal organic skeleton and the carbon quantum dot. The constitution components of the catalyst are easily adjusted, andthe metal organic skeleton material with amino and the carbon quantum dot with carboxylic acid can be arbitrarily selected. The method is simple in synthesis process flow and strong in operability and has wide application prospects.
