Photocatalytic Performance of RGO/MOF Based Composites

  • Reduced graphene oxide (RGO) and Cu-BTC are adopted to modify TiO2 to promote photocatalytic performance. The morphologies of the as-prepared composites are obtained by SEM, and the rhodamine-B (RB) is employed to estimate the UV- and visible-light activities. Moreover, the lifetime of photoinduced electrons and EPR profiles of the resulting photocatalysts are recorded, revealing the functions of the RGO and Cu-BTC, and the corresponding photocatalytic mechanism is also proposed. After optimizing the mass fractions of various components to achieve the synergy, the rate constants of RB under UV- and visible-light illumination reach 1.44×10−1 and 9.2×10−2 min−1, respectively. High recycling and using stability of the optimized sample indicates the potential application prospect.
