In-situ synthesis of nanomagnetites on poly(amidoamine)-modified graphite oxides and their novel catalytic performances towards the degradation of p-nitroaniline

- Hybrids of modified GO and in-situ synthesized magnetite were prepared.
- The hybrid performed light-free catalyses on degradation of p-nitroaniline.
- Air and aqueous medium were indispensible for the degradation.
- The degradation performed fluently without adding H2O2 or pH adjusting.
- Such novel properties differed from those of most reported GO hybrids.
