“…It can be seen from Figure 2c that there are four main peaks at 2θ values of 38.5°, 44.6°, 64.8°, and 77.7°. These peaks correspond to (1,1,1), (2,0,0), (2, 2,0), (3,1,1) diffraction planes of Ag crystals (Ming et al, 2019;Parida et al, 2020;Shen and Feng, 2018), which further corroborates that the surface of the CS ber is indeed AgNPs. With the increase of AgNO 3 concentration, the diffraction peak at 38.56° becomes more intense, and the half-value width decreases from 0.697° (CS@Ag-12) to 0.468° (CS@Ag-36).…”
