Abstract: A certain amount of TiB2 was added to deionized water and uniformly dispersed. Then, H₂O₂ was added and the mixture was continuously stirred at low temperature. After the reaction was completed, the solution was centrifuged and the precipitate was discarded. The supernatant was taken to obtain the boron-loaded titanium oxide (TiOx@B) after the stripping process. A separate Co²⁺/Ni²⁺ solution and solutions with different proportions of Co²⁺ were mixed with the TiOx@B solution to load Co²⁺. The TiOx@B after loading was mixed with sodium alginate to prepare the casting solution. The solution was cross-linked with calcium ions to prepare the Co²⁺/TiOx@B-CaAlg composite membrane. The mechanical properties of the composite membrane and its catalytic degradation performance for orange-yellow G pollutants were studied.
