| Abstract: |
| Cellulosic fiber paper base containing various filler content (PCCP)/metal-organic framework compound (MOFs[LCP-1]) composite (PCCP/LCP-1) was prepared by in-situ growth method. The present work investigated the effect of filler precipitated calcium carbonate (PCC) content on the gas adsorption performance. The bonding modes of LCP-1 and cellulosic fibers, as well as the surface morphology, specific surface area, thermal stability and adsorption behavior of composites were characterized by FT-IR, XRD, SEM, TGA and BET. Results showed that ester bonds existed between LCP-1 and the cellulosic fibers. The increase of PCC content helped to expose more free hydroxyl groups in cellulosic paper, which was beneficial to the deposition rate of LCP-1 on the paper surface. Moreover, the addition of PCC could confine the growing space of LCP-1, resulting in the smaller size of LCP-1. Nitrogen adsorption data showed that the use of PCC could significantly improve the adsorption performance of the composite. The adsorption amount increased as the PCC addition increased from 10% to 40% compared with the composite without PCC. |
