Fabrication of Ni-AC/TiO₂ Composites and their Photocatalytic Activity for Degradation of Methylene Blue

다국어 초록 (Multilingual Abstract)

Activated carbon modified with nickel (Ni-AC) was employed the for preparation of Ni-activated carbon/TiO₂ (Ni-AC/TiO₂)
composites. The N₂ adsorption data showed that the composites had a decreased surface area compared with pristine AC. This
indicated blocking of the micropores on the surface of the AC, which was further supported by observation via SEM. XRD results
showed that the Ni-AC/TiO₂ composite contained a mixed anatase and rutile phase while the untreated AC/TiO₂ contained only a
typical single and clear anatase phase. EDX results showed the presence of C, O, and Ti with Ni peaks on the composites of Ni-
AC/TiO₂. Subsequently, the photocatalytic effects on methylene blue (MB) were investigated. The improved decomposition of MB
showed the combined effects of adsorptions and photo degradation. In particular, composites treated with Ni enhanced the photo
degradation behaviors of MB.
