摘要：

To prepare cotton fabrics with photocatalytic properties, the in-situ growth of polyacids on cotton fabrics was achieved by introducing metal organic framework materials into which polymetallic oxides of suitable dimensions were loaded. The effects of metal ion reaction time, amount of polymetallic acid, organic ligand and reaction time of polymetallic acid on the photocatalytic performance of the prepared cotton fabrics loaded with polymetallic organic framework material (POMOF) were investigated, and the morphology and structure of cotton fabrics loaded with POMOF were characterized with the aid of scanning electron microscopy and FT-IR spectrometry. The results show that the carboxylation modification of cotton fabrics is able to form multiple active sites on its surface, and the degradation rate of cotton fabrics loaded with POMOF to Rhodamine B solution (10 mg/ L) reached 92. 23% in 135 min when the modified cotton fabric was reacted in copper nitrate solution for 12 h, the amount ratio of homophthalic acid to polytungstate was 1 ∶4, and the reaction time of organic ligand and polyacid was 10 h. This cotton fabric loaded with POMOF demonstrated good photocatalytic performance and has great potential in the degradation of printing and dyeing wastewater. © 2022 China Textile Engineering Society.
