“…Sci. [265] In another work, CdS nanorods were facilely sandwiched between g-C 3 N 4 and RGO nanosheets via a wet-chemical approach. In Chen's work, C 3 N 4 /RGO hybrids were produced via a layer-by-layer assembly method to fabricate a paper-sensing chip for selective detection of NO 2 and SO 2 gas by using "light on" and "light off" fashions, respectively.…”

The discovery of graphene and subsequent verification of its unique properties have aroused great research interest to exploit diversified graphene‐analogous 2D nanomaterials with fascinating physicochemical properties. Through either physical or chemical doping, linkage, adsorption, and hybridization with other functional species into or onto them, more novel/improved properties are readily created to extend/expand their functionalities and further achieve great performance. Here, various functionalized hybridizations by using different types of 2D nanomaterials are overviewed systematically with emphasis on their interaction formats (e.g., in‐plane or inter plane), synergistic properties, and enhanced applications. As the most intensely investigated 2D materials in the post‐graphene era, transition metal dichalcogenide nanosheets are comprehensively investigated through their element doping, physical/chemical functionalization, and nanohybridization. Meanwhile, representative hybrids with more types of nanosheets are also presented to understand their unique surface structures and address the special requirements for better applications. More excitingly, the van der Waals heterostructures of diverse 2D materials are specifically summarized to add more functionality or flexibility into 2D material systems. Finally, the current research status and faced challenges are discussed properly and several perspectives are elaborately given to accelerate the rational fabrication of varied and talented 2D hybrids.

“…The role of reduced graphene oxide (rGO) as an effective solid-state electron mediator has been exploited to enhance the interfacial contact between CdS and PCN in a Z-scheme system. 113 This hybrid photocatalyst comprised of CdS coupled rGO dispersed on exfoliated PCN nanosheets was prepared by hydrothermal approach. A remarkably enhanced H 2 production rate was obtained for the Z-scheme CdS/RGO/PCN composite containing the optimal content of PCN (50 wt.%) (676.5 µmol g −1 h −1 ) with an excellent quantum efficiency (36.5%).…”

The solar-to-chemical energy conversion is promising to tackle sustainability challenges toward a global future. The production of H 2 from sunlight represents an attractive alternative to the use of carboniferous fossil fuels to meet our energy demands. In this context, the water splitting reaction photocatalyzed by semiconductors that can be excited under visible or near-infrared light excitation represents an attractive route to the clean generation of H 2. In this review, we present an overview of the most important concepts behind the H 2 generation, from water splitting, promoted by semiconductor-based systems for readers that were recently introduced to the water splitting topic. Then, we present the main classes of photocatalysts based on semiconductors. For each class of semiconductors, we focused on the examples that lead to the highest activities towards the H 2 production and discuss the operation principles, advantages, performances, limitations, and challenges. We cover metal oxides, sulfides, and nitrides. We also discuss strategies in which these materials are combined, including hybridization with metal nanoparticles, other semiconductors, and carbon dots, to achieve improved performances and circumvent the limitations of the individual counterparts.
