1. A ceramic-based composite material used for low-concentration formaldehyde degradation characterized in that:
using alkali metal-transition metal-TiO2 as an active component, the alkali metal-transition metal-TiO2 comprising A-T-TiO2, using metal organic framework/aminated ceramic foam as a carrier, the metal organic framework/aminated ceramic foam comprising MOF/NFC, and a formula of the ceramic-based composite material is A-T-TiO2/MOF/NFC, where A represents one of Na, K, and Li, T represents one of Cu, Mn, and Co, and MOF represents one of ZIF-8, MOF-199, and UIO-66-NH2, NFC represents an aminated foam ceramic comprising Al2O3 ceramic or ZrO2 ceramic; in terms of weight percentage, the active component in the ceramic-based composite material is 3-10%, the carrier is 90-97%, and a sum of the two is 100%; a weight percentage in the active component A:T:TiO2 is (5-10):(10-20):(70-85), and a weight percentage in the carrier, MOF:NFC is (4-6):(94-96).
