Cotton fabric was plasma treated and then loaded with Ag6Si2O7 by in-situ precipitation to prepare plasma-treated/Ag6Si2O7-loaded cotton fabric and the effects of treatment parameters on its photocatalytic activity were studied. Plasma treatment facilitated more efficient loading of Ag6Si2O7 on plasma-treated cotton fabric, which was confirmed by SEM, XRD and EDS. The plasma-treated/Ag6Si2O7-loaded cotton fabric had efficient photocatalytic activity in UV-visible region illustrated by UV-vis DRS. With the increasing treatment time, the degradation ratio of MB solution by plasma-treated/Ag6Si2O7-loaded cotton fabric increased first and then decreased, and it increased first and then almost remained unchanged with the increasing output power.

Spherical magnetic Fe3O4 nanoparticles with different Nd doping amounts were successfully prepared using a simple hydrothermal method. The products were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic laser scattering particle size (DLS), and vibrating sample magnetometer (VSM) analysis. Results showed that the spherical nanoparticles of pure Fe3O4, pure Nd2O3, and Nd-Fe3O4 were confirmed by XRD and TEM. The size of the prepared nanoparticles decreased first and then increased with increasing Nd doping amount by dynamic laser scattering. In addition, magnetic parameters, including saturation magnetization, remanent magnetization, and coercivity of Fe3O4 nanoparticles with different doping ratios of Nd, were analyzed by VSM.
