The present disclosure discloses a process for improving the surface catalytic efficiency of a catalyst substrate. In some embodiments, to use nano-catalyst particles more efficiently, a process uses a porous substrate as a stationary phase support and disperses the nano-catalyst particles uniformly in all the internal space of the porous substrate, such that reactants flow through the porous substrate to achieve a catalytic effect. In some embodiments, the process not only improves the use efficiency of nano-catalyst particles, but also enables easier and more convenient adjustment of various parameters of a catalytic reaction.

A method for efficiently catalyzing furfural to prepare cyclopentanone, and a catalyst and preparation method therefor, are disclosed, in the field of biomass catalytic conversion. The catalyst comprises uniformly dispersed metal active center nanoparticles and oxides obtained by LDHs calcination. The metal active center is single atom Pt/Cu alloy; the LDHs is used as a precursor to prepare a Cu-containing catalyst precursor; after a reduction in H.sub.2 atmosphere, small amount of Pt.sup.2+ is used for reacting with the Cu-containing catalyst precursor to obtain a monoatomic Pt/Cu catalyst; said catalyst is used to catalyze hydrogenation of an aqueous phase of furfural to prepare cyclopentanone, wherein the reaction temperature is 120-250° C., the reaction pressure is 0.1-5 MPa, the reaction time is 0.5-24 hours, and the reaction solvent is ultrapure water. Low-cost and efficient, the catalyst catalyzes the hydrogenation of an aqueous phase of furfural to prepare cyclopentanone. When the reaction is carried out at 160° C. at an initial pressure of 0.1 MPa for 1 hour, the furfural is completely converted, and the yield of the cyclopentanone reaches 99%.
