The use of carbon materials as anchors for tiny semiconductor nanoparticles in photocatalysis has become a common practice due to their numerous advantages (Fig. ) . First, carbon materials provide a large surface area framework that facilitates the distribution and immobilization of nanoparticles. For instance, Shen et al. demonstrated the use of reduced graphene oxide (rGO) to stabilize ultra-thin Zn₀.₅Cd₀.₅S nanorods, significantly enhancing photocatalytic hydrogen (H₂) production. Second, these carbon compounds can easily pair with nanoparticles while retaining their structure and properties due to their heat stability and chemical inertness. Carbon materials can
