A novel poly(ethylene glycol)‐based nanocomposite hydrogels containing Fe‐octacarboxylic acid phthalocyanine (FeOCAP)/magnetic attapulgite was successfully synthesized by in situ polymerization. Fourier transform infrared spectroscopy result showed the FeOCAP/magnetic attapulgite was successfully introduced into the hydrogels matrix. Besides, the hydrogen bond interactions existed between FeOCAP/attapulgite and hydrogels, which acted as the crosslink points in the hydrogels network, and meanwhile, stabilized the nanoparticles in hydrogel without phase separation. Photocatalytic activity studies confirmed that the as‐prepared nanocomposite hydrogels had excellent photocatalytic activity for rhodamine B photodegradation, as compared to the pure hygrogels. The rhodamine B removal percentage of the hydrogels could reach nearly 100% and the kinetics of photocatalytic degradation reaction was described by the Langmuir–Hinshelwood kinetics models. The hydrogels could be reused more than five times without losing any photodegradation ability, which indicated that the hydrogels would be potentially useful in dyes wastewater treatments. © 2017 Wiley Periodicals, Inc.
