Summary: A strategy for enhancing the oxygen evolution reaction (OER) catalytic activity of NiFe layered double hydroxide (LDH) by incorporating CoTe nanosheets (NSs) is reported. The hybrid material (CoTe NS/NiFe LDH) exhibits a hierarchical 2D-2D heterostructure with an intact interface between the CoTe NS and NiFe LDH. The presence of CoTe NS on the NiFe LDH enhances charge transfer and reaction kinetics during the OER process, leading to lower overpotentials and excellent stability, outperforming the benchmark RuO2 catalyst.

Summary: The controllable adjustment of layered double hydroxide layer spacing has enabled its use as an electrode material for energy storage and electrochemical hydrogen evolution. However, lower conductivity and agglomeration have limited its large-scale application. In this study, sodium dodecyl sulfate (SDS) intercalation modification was used to construct LDH derivatives with vertically grown CoNi-SDS-LDH nanosheets on a nickel foam surface, resulting in a layered structure supported by nanowires which improved ion transport efficiency and reduced agglomeration. The electrode material demonstrated good electrochemical performance, with a cycling stability of 91% after 10,000 cycles and 98.1% performance retention after 10 hours of hydrogen evolution test. This anionic modification offers the potential for large-scale applications of LDH in flexible supercapacitors and electrocatalytic hydrogen evolution.

Summary: In this study, Cu-doped NF-LDHs with a self-supported 2D nanosheet structure on carbon cloth were developed to enhance OER activity and stability through modulating the electronic configuration by interactions among Ni-Fe-Cu. The addition of Cu successfully reduced the activation energy for OER, resulting in small overpotentials and high current densities, demonstrating superior performance compared to nickel-LDHs and NF-LDHs. Additionally, excellent electrochemical stability was achieved during long-term OER tests, indicating no dissolution of active metals due to synergetic effects among Ni-Fe-Cu.

Summary: It was found that mannitol could be used to selectively create oxygen vacancies (Ovs) in Bi2MoO6 (BMO) and form short nanorods (SNRs), and the Ov content, SNR size, and surface area of the sample could be effectively tuned by pH.

Summary: The photoexcited charge separation efficiency is usually considered as the key factor for enhancing the photocatalytic activity of photocatalysts. However, the role of the interfacial affinity between photocatalysts and substrates is rarely studied systematically. In this study, nitrogen vacancy-modified polymeric carbon nitride porous nanotubes (PCNpts) were synthesized and showed significant improvements in surface area, wettability, photoabsorption, charge separation capability, and photocatalytic activity in water splitting. Interestingly, the photoactivity of PCNpts showed substrate-dependent variation in contaminant degradation compared with bulk PCN. It was found that the interfacial affinity between PCNpts/PCN and contaminants/H2O, rather than the photoabsorption and charge separation capability, dominated their photoactivity.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
