“…Figure 2c has two peaks at 71.0 and 74.4 eV, which correspond to Pt4f , while Figure 2a has two peaks at 314.8 and 330.1 eV that belong to Pt4d . [26] This confirms that platinum (Pt) exists in its zero-valent state in the Pt/GO composite. Calculating the peak area revealed that the composite includes 5.1 mass% Pt, 14.6 mass% oxygen (O), and 80.3 mass% carbon (C).…”

In this paper, we propose and implement an in situ direct reduction reaction of K2PtCl6 precursor under mild reaction conditions using topotaxial reaction and the reducbility of graphene oxide. The reduced product platinum atom clusters are intercalated onto the GO surface, resulting in platinum nanocatalyst. The structure, content, and morphology of Pt/GO composites are studied using X-ray dif-fraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS), among other methods. It has been demonstrated that Pt4+ ions in the K2PtCl6 precursor are reduced to Pt0 atoms under moderate reaction conditions, which are equally distributed across the GO surface in the form of atom clusters with an average particle size of 10 nm. The platinum nanocluster has a conventional face-centered cubic crystal structure, with Pt crystal planes (111), (200), (220), and (311) etc.

In this review, we first focus on summarizing recent advances in effective and facile strategies for the ration synthesis of noble metal chalcogenide nanomaterials (NMCNs), and then, we systematically introduce their applications in catalyzing typical electrochemical reactions. Finally, we make some perspectives on the challenges for using NMCNs in electrocatalysis with respect to further enhancement of their electrocatalytic performance.
