Hydrogen generation from the direct splitting of water by photocatalysis is regarded as a promising and renewable solution for energy crisis. The key to realize this reaction find an efficient robust photocatalyst that ideally makes use sunlight. Recently, due attractive properties such appropriate band structure, ultrahigh specific surface area, more exposed active sites, two-dimensional (2D) photocatalysts have attracted significant attention photocatalytic splitting. This Review attempts...
Abstract Hydrogen production through facile photocatalytic water splitting is regarded as a promising strategy to solve global energy problems. Transition‐metal carbides (MXenes) have recently drawn attention potential co‐catalyst candidates for photocatalysts. Here, we report niobium pentoxide/carbon/niobium carbide (MXene) hybrid materials (Nb 2 O 5 /C/Nb C) photocatalysts hydrogen evolution from splitting. The Nb C composites were synthesized by one‐step CO oxidation of CT x . grew...
The separation of photogenerated carriers and photocatalytic hydrogen production efficiency was greatly enhanced by the 2D/2D heterojunction Ti<sub>3</sub>C<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub>.
Titanium dioxide (TiO2) represents a promising candidate for hydrogen production via photocatalysis. However, its large bandgap and fast charge recombination limits efficiency. To overcome this limitation, we explored in work two-dimensional titanium carbide MXene, Ti3C2Tx (Tx = O, OH, F), as feasible co-catalysts with TiO2 the photocatalyst. We synthesized series of Ti3C2Tx/TiO2 composite photocatalysts monolayer co-catalyst to improve separation photoinduced electrons holes. The...
Constructing an efficient photoelectron transfer channel to promote the charge carrier separation is a great challenge for enhancing photocatalytic hydrogen evolution from water. In this work, ultrathin 2D/2D Ti3 C2 Tx /ZnIn2 S4 heterostructure rationally designed by coupling ZnIn2 with few-layered via electrostatic self-assembly strategy. The possesses larger contact area and strong electronic interaction at interface, sulfur vacancy on acting as electron trap further enhances of...
This paper reviews the surface engineering, including termination groups, functionalization, defects and oxidation, of MXenes, their impact on energy environmental applications MXenes.
Severely polluting wastewater containing heavy metal ions has become a pressing issue. To address the current shortcomings of natural bentonite (Bent) and carboxymethyl cellulose sodium (CMC) for Cd(II) adsorption, this study developed cellulose/bentonite composite adsorbent (CMCMW-Bent) via microwave-assisted synthesis using acrylic acid (AA)-modified CMC pretreated (Bent), was used to remove from wastewater. The results show that strong interaction between AA CMC, which successfully...
Two-dimensional (2D)-structured photocatalysts with atomically thin layers not only have the potential to enhance hydrogen generation efficiency but also allow more direct investigations of effects surface terminations on photocatalytic activity. Taking 2D Bi2WO6 as a model, we found that configuration bilayer Bi2O2 sandwiched by alternating WO4 enabled thermodynamic driving for evolution. Without Pt deposition, H2 can reach 56.9 μmol/g/h compared no activity nanocrystals under simulated...

Two-dimensional (2D) photocatalysts have attracted considerable research interest in the past decades due to their unique optical, physical and chemical properties. Constructing 2D/2D heterojunctions with large interface area has been considered as an effective approach enhance transfer rate separation efficiency of charge carriers, leading dramatic increase photocatalytic performance photocatalysts. Here, state-of-the-art progress on based 2D materials is reviewed, including photocatalysis...
The CuO–Fe2O3–ZrO2/HZSM-5 bifunctional catalyst was prepared and used for the direct synthesis of dimethyl ether (DME) from CO2 H2. results revealed that doping CuO–Fe2O3 with ZrO2 might increase specific surface area change chemical combination state CuO by decreasing outer-shell electron density Cu via an obvious in interaction between Fe2O3. Addition to strongly affects hydrocarbon selectivity. When using system, both conversion yield DME were much higher than those obtained...
In the quest for highly efficient coke-resistant catalysts dry reforming of methane (DRM) to produce syngas, a series Ni–In/γ-Al 2 O 3 with various Ni contents were prepared via “two-solvent” method and used DRM reaction.
