1：Experimental Design and Method Selection:

The study employs a two-step synthetic route involving pyrolysis of bimetallic ZnCo-ZIFs to form oxides, followed by hydrothermal sulfidation with Na2MoO4 and CH3CSNH2 to simultaneously form ZnCoS solid-solution and load few-layered 1T-MoS2. This design leverages MOF templating for structural control and mutual sulfur sharing for phase stabilization.
