Fig. 2From: Surfactant-Tuned Phase Structure and Morphologies of Cu2ZnSnS4 Hierarchical Microstructures and Their Visible-Light Photocatalytic ActivitiesXRD patterns of CZTS hierarchical microstructures synthesized at 200 °C for 48 h with the different amounts of tartaric acid (TA), such as 1:2, 1:4, and 1:8. The standard patterns of the kesterite CZTS (JCPDS card no. 26-0575) and CuS (JCPDS card no. 06-0464) are shown below as referenceBack to article page
