Designing and developing visible-light-responsive materials for solar to chemical energy is an efficient and promising approach to green and sustainable carbon-neutral energy systems. Herein, a facile in situ growth hydrothermal strategy using Mo-modified ZnIn 2 S 4 (Mo-ZIS) nanosheets coupled with NiTiO 3 (NTO) microrods to synthesize multifunctional Mo-modified ZIS wrapped NTO microrods (Mo-ZIS@NTO) photocatalyst with enhanced interfacial electric field (IEF) effect and typical S-scheme heterojunction is reported. Mo-ZIS@NTO catalyst possesses wide-spectrum light absorption properties, excellent visible light-to-thermal energy effect, electron mobility, charges transfer, and strong IEF and exhibits excellent solar-to-chemical energy conversion for efficient visible-light-driven photocatalytic hydrogen evolution. Notably, the engineered Mo 1.4 -ZIS@NTO catalyst exhibits superior performance with H 2 evolution rate of up to 14.06 mmol g −1 h − 1 and the apparent quantum efficiency of 44.1% at 420 nm. The scientific explorations provide an in-depth understanding of microstructure, S-scheme heterojunction, enhanced IEF, Mo-dopant facilitation effect. Moreover, the theoretical simulations verify the critical role of Mo element in promoting the adsorption and activation of H 2 O molecules, modulating the H adsorption behavior on active S sites, and thus accelerating the overall catalytic efficiency. The photocatalytic hydrogen evolution mechanism via S-scheme heterojunction with adjustable IEF regulation over Mo 1.4 -ZIS@NTO is also demonstrated.

“…[ 86 ] Besides, 0D metal carbide provides more active sites for photocatalytic reactions because of a high specific surface area of quantum dots. [ 87 ] Excepting for 0D metal carbide, 1D metal carbide, such as nanowires and nanotubes, can work as high‐efficiency cocatalysts. This is because linear metal carbide is beneficial to long‐distance electron transportation and electron‐hole separation efficiency.…”

Semiconductor‐based photocatalytic solar‐to‐fuel conversion has proven an appealing strategy for achieving carbon‐neutral and green‐hydrogen production. However, almost all semiconductors exhibit unsatisfactory photocatalytic performance due to insufficient surface‐active sites, weak selectivity, and fast charge‐carrier recombination. For these reasons, cocatalyst loading has become an encouraging strategy for improving photocatalytic activity and selectivity. Owing to the scarcity, and cost of noble metal‐based cocatalysts, utilization of low‐cost noble‐metal‐free cocatalysts, such as metal carbide‐based cocatalysts, has aroused tremendous attention. This review highlights some recent crucial advances in active metal carbide‐based cocatalysts for photocatalytic solar‐to‐fuel conversion. First, the fundamentals of metal carbide‐based cocatalysts are presented, including the photocatalytic mechanism, advantages, drawbacks, and design rules. Second, three synthesis approaches of high‐active metal carbide‐based cocatalysts, namely constructing metal carbide nanostructures, epitaxial synthesis of metal carbides on nanostructured carbon, and crystal imperfection construction on metal carbides, are thoroughly addressed. Subsequently, applications of metal carbide‐based cocatalysts in photocatalytic hydrogen production, CO2 reduction, and nitrogen reduction are further discussed. Finally, the crucial challenges and important directions of metal carbide‐based cocatalysts for photocatalytic solar‐to‐fuel conversion are proposed. This review demonstrates some new options for rationally designing and developing novel and efficient metal carbide‐based cocatalysts for highly active and selective photocatalytic solar‐to‐fuel conversion.

“…[ 45 ] To address these issues, g‐C 3 N 4 was combined with molybdenum (Mo) and N‐doped carbon material. [ 46 ] This material was capable of delivering superior H 2 evolution rate of 1.7 mmol h −1 g −1 , which is over 200 times greater than that of pristine g‐C 3 N 4 . The impressive performance of the hybrid material as a photocatalyst highlights the importance of N‐doped carbon materials and the synergistic effects involved when combined with existing materials.…”

Carbon materials play an integral role in our everyday lives. Extensive research has been carried out on the applications of carbon materials in its various morphologies and properties. The addition of dopants in carbon materials, whether in situ or post‐treatment, has gained significant interest and has driven researchers to explore its benefits and address existing issues. Nitrogen doping, in particular, has been shown to be a highly effective strategy in creating advanced materials for various applications, such as CO2 capture, energy conversion, and energy storage. However, the key factors that contribute to the properties and performance of the material, such as method of synthesis, starting materials, level of doping, and porosity, should be considered and studied at great depths. In this review, the synthesis methods of N‐doped carbon materials and their recent progress in CO2 adsorption, energy conversion, and energy storage applications is discussed. These applications represent some of the most important and promising solutions to burgeoning issues in environmental and energy fields. In addition, the remaining issues with N‐doped carbon materials and the possible strategies to overcome them will be discussed.
