From: Template Route to Chemically Engineering Cavities at Nanoscale: A Case Study of Zn(OH)2 Template

Figure 1

The scheme for constructing hollow octahedron by using Zn(OH)2 as template. Process I: Surface chemical conversion of Zn(OH)2 template with S2− [Step 1]. Cation exchange can be performed on the surface of Zn(OH)2/ZnS architectures, generating various Zn(OH)2/sulfide core/shell structures [Step 2]. A core removal results in various nanoscale sulfide cavities. Process II: Chemical deposition on Zn(OH)2 template [Step 1], following a core removal step [Step 2]
