AI Article Synopsis
- A crosslinked carboxymethyl starch (CCMS) was created from corn starch using epichlorohydrin and chloroacetic acid through crosslinking and etherification processes.
- Nano-TiO was integrated onto the CCMS surface using the sol-gel method, producing a TiO/CCMS composite, which was analyzed with various characterization techniques including XPS, XRD, SEM, and BET.
- The results demonstrated that the TiO/CCMS composite exhibited enhanced properties, such as a larger surface area and effective synergies in adsorption and photodegradation under UV light.
Article Abstract
In this paper, a crosslinked carboxymethyl starch (CCMS) was prepared with corn starch as the raw material, epichlorohydrin as the crosslinking agent, and chloroacetic acid as the etherifying agent through a series of crosslinking, alkalization, and etherification reactions, respectively. Nano-TiO was loaded onto the surface of the CCMS by the sol-gel method to obtain a TiO/CCMS composite. The TiO/CCMS composite was characterized by XPS, XRD, SEM, and BET. XPS showed that the surface chemical composition of the TiO/CCMS composite material contained titanium; XRD diffraction patterns indicated that the crystal form of the TiO/CCMS composite was a combination of the CCMS and anatase TiO. The surface morphology obtained by SEM showed that there were nano-TiO particles on the surface of the CCMS. The specific surface area of the TiO/CCMS composite was larger than that of CCMS. The adsorption-photodegradation performance of the TiO/CCMS composite was also studied under UV irradiation, and the results showed that significant adsorption-photodegradation synergies occurred.
