Summary: Hierarchical structures composed of MoS2 nanosheets grown on Bi2S3 nanorods were prepared via hydrothermal reaction. The innovative heterostructures with distinct porosity and close interfacial contact facilitate effective visible-light utilization and provide permeable routes for reactant molecules to enter the inner structure. The Bi2S3 @MoS2 heterostructure with 50% MoS2 exhibited superior adsorption and photodegradation of Rhodamine B, reaching 97.5%. Toxic heavy metal ions and organic pollutants in water can be eliminated using attractive heterostructures with excellent adsorption capacities and photocatalytic activities.

Summary: This study presents a two-step method for achieving high-quality single-crystal tellurium (Te) core fibers with high transmittance and thermoelectric performance. The method involves thermal drawing of a precursor fiber into polycrystalline Te core fibers, followed by recrystallization using a continuous laser to produce single-crystal fibers. These single-crystal Te core fibers demonstrate superior performance compared to previous reports and have potential applications in optical fibers, functional fibers, and integrated devices.

Summary: In recent years, single-atom adsorbents (SAAs) have attracted extensive research interest as a novel class of adsorption materials with maximized atom utilization and uniform isolated adsorption sites. However, gaining a fundamental understanding of the complex behaviors of SAAs for adsorbing thiophenic compounds (THs) remains challenging. This work systematically investigates the mechanisms of adsorption desulfurization (ADS) over single group IIIA metal atoms (Ga, In, and Tl) anchored on hexagonal boron nitride nanosheets (BNNSs) through density functional theory (DFT) calculations. The results reveal the stabilities, substitution preferences, and enhanced adsorption capacities of SAAs for THs, providing insights for the design and application of SAAs in the field of ADS.

Summary: A 3D flower-like MoS2/Bi2S3 heterojunction was synthesized successfully, showing enhanced photocatalytic activity and electrochemical performance. The effective separation of charge carriers between Bi2S3 and MoS2 contributes to the improved photocatalytic activity, while the heterojunction exhibits significantly higher capacitance as a supercapacitor electrode compared to pure Bi2S3. The findings suggest a promising potential for metal sulfides heterojunction in multifunctional applications.

Summary: In this work, ordered CuO nanorods were grown on 2D Cu/g-C3N4 nanosheets to form hierarchical CuO@Cu/g-C3N4 nanorods film, which exhibited excellent lithium storage performance. The outstanding stability and cyclic performance of this freestanding anode were attributed to the unique 2D nanostructure, ordered CuO nanorods, Cu nanosheets, and porous g-C3N4 nanosheets, providing large exposed area for Li+ insertion, pathways for charge and Li+ transfer, electrons transport, and active sites for Li+ transport and accommodating volume change. This strategy of growing ordered nanostructures on 2D nanosheets is considered an effective way to enhance transition metal oxides for advanced lithium-ion batteries.

Summary: In this study, a kinetics-assisted identification method combined with theoretical calculations was used to identify and regulate the active sites of Pd catalysts for propyne hydrogenation. The results showed that Pd(111) sites were the dominant active sites for propyne conversion and propylene formation, while Pd(100) sites were responsible for propane formation. Furthermore, electron-rich Pd catalyst exhibited higher activity and selectivity, and electron regulation enhanced the selective hydrogenation of propyne.

Summary: A particle-resolved CFD method has been developed to calculate the fluid-to-particle mass and heat transfer coefficients in packed beds. The method incorporates axial dispersion and has been validated for different tube-to-particle diameter ratios and particle shapes. Including axial dispersion increases the transfer coefficients by 5%-57% and 9%-63%. The transfer coefficients decrease as the diameter ratio decreases. Particles without inner holes exhibit higher coefficients than those with inner holes. Trilobes have the highest coefficients, surpassing spheres by 85% and 95%. This study offers a versatile method and useful guidance for packed bed reactor design.

Summary: In this study, a novel hybrid hole conductor, Poly-3-hexylthiophene - CsPbI3 quantum dots (P-QD), was used to improve hole extraction in CsPbI2Br C-PSCs. The P-QD hybrid hole conductor effectively improved hole extraction by aligning perovskite/carbon energy-level and extending the optical response range of CsPbI2Br solar cells, resulting in an increased power conversion efficiency from 13.49% to 15.04%. This strategy provides a new approach for the construction of hole transport layers in carbon-based perovskite solar cells.

Summary: A strategy for constructing an all-inorganic 2D/3D CsPb2I4Br/CsPbI2Br bulk heterojunction (BHJ) by in situ reaction of excess PbI2 in a precursor solution with CsPbI2Br during annealing is proposed. The formed 2D/3D BHJ effectively passivates defects in 3D CsPbI2Br and reduces nonradiative recombination loss in carbon electrode-based perovskite solar cells (C-PSCs). The optimized C-PSCs achieve an open-circuit voltage of 1.32 V and an efficiency of 15.25%, which are the best results for CsPbI2Br-based C-PSCs.

Summary: A ligand design strategy using mercaptopropionic acid (MPA) and inorganic ligands (ILs) as dual ligands on the surface of quantum dots (QDs) is developed to enhance the loading amount and optoelectronic performance of QD sensitizers. The ILs not only facilitate QD loading but also reduce interdot repulsion and form dense QD layers, while the pseudohalide SCN- has a passivation effect on QD surfaces and suppresses defect trap states. As a result, QDSCs based on dual SCN/MPA ligands achieve a certified efficiency of 16.10%, a new record for liquid junction QD solar cells.

Summary: Kinetics experiments were conducted to investigate the liquid-phase 1-butene hydroisomerization over a commercial Pd/Al2O3 catalyst. Three intrinsic kinetics models were proposed to describe the reaction rates. The results showed that the selectivity towards 2-butene increased with temperature, and the fraction of hydrogen in reactants significantly affected the conversion rate and selectivity. The single-site Langmuir-Hinshelwood model was found to be the most accurate in predicting the experiments.

Summary: In this study, a mild continuous pH control strategy using urea as a weak organic base was proposed to regulate the hydrolysis process of TiCl4 post-treatment. This strategy facilitated the formation of an anatase-dominated TiO2 surface layer on the mesoporous TiO2, leading to reduced defect density and improved charge extraction efficiency in perovskite solar cells (PSCs). The fabricated carbon electrode-based PSCs (C-PSCs) achieved an efficiency of 18.08%, the highest among C-PSCs based on wide-bandgap perovskites.
