Abstract

A novel nitrogen doped carbon photocatalyst was successfully prepared from the carbonization of copper phthalocyanine (CuPc) on/in zeolitic imidazolate framework-8 (ZIF-8) hybrid. Carbonized catalysts derived from either ZIF-8 or CuPc exhibit poor activity towards the degradation of dyes (such as methyl orange (MO) and Rhodamine B (Rh B)), whereas carbonized CuPc complex supported on ZIF-8 exhibits extremely high performance. The weight ratios 1:2 and 1:8 of CuPc/ZIF-8 showed the high dye absorption activity, while the weight ratio 1:4 demonstrated the high photocatalytic activity in the presence of H2O2 as an oxidant. For the first time, the photocatalyst (Cu/N-PC) was used in Csingle bondH activation of formamides in the presence of tert-butyl hydroperoxide (TBHP) as an oxidant. The reaction proceeded within 30 min, in the presence 0.02 mol% of Cu.
