“…29 In the past decades, 2D layered materials have gradually become the focus of materials science by virtue of their unique layered structural properties and good optoelectronic properties. [30][31][32][33][34][35] Reduced graphene oxide (rGO), as one of the 2D materials, stands out for supercapacitor applications due to its remarkable electrochemical properties, high surface area, and excellent electronic properties. [36][37][38][39][40] Thus, carbonbased (such as rGO, porous carbon (PC), MXene, etc.)…”
