Three-dimensional PANI/CdSNRs-SiO2 hydrogel (CdS NRs-PANI-SiO2) was synthesized by loading polyaniline (PANI) onto the semiconductor CdS nanorods (NRs) surface and loading the binary complex on SiO2 gel. The structure. optical properties. and electrochemical properties of the composite were studied in detail. https://cuttingedgecutleryco.shop/product-category/blade-paste/
