Summary: Linker-assisted assembly (LAA) was used to connect CdS quantum dots (QDs) to MoS2 nanosheets, forming ligand-bridged CdS/MoS2 heterostructures for redox photocatalysis. LAA allowed precise control over the light-harvesting properties of QDs within the heterostructures. The transfer of electrons from CdS QDs to MoS2 nanosheets was tunable with the properties of bridging ligands. The charge separation across the CdS/MoS2 interface was crucial for the photocatalytic activity of CdS-L-MoS2 heterostructures.

Summary: Several transition metal oxides and hydroxides have shown promising electrocatalytic activity for the oxidation of 5-hydroxymethyl furfural (HMF), an important biomass-derived compound. However, little is known about the factors influencing the reactivity and selectivity of these materials for HMF electrooxidation (HMFOR). In this study, Co, Ni and Cu-based Prussian blue analogue (PBA) electrocatalysts were investigated to understand their intrinsic electronic contributions to HMFOR activity. Cu-phase PBAs exhibited the highest faradaic efficiency for generating 2,5-furandicarboxylic acid (FDCA) during HMF oxidation. The presence of nucleophilic OH* species on the electrocatalyst's surface was identified as an important factor affecting the activity and selectivity towards FDCA. These findings provide insights into the design of high-performance HMFOR catalysts without relying on catalysts with high oxygen evolution reaction (OER) activity.

Summary: In this study, a defect-rich SrTiO3-x coating was applied on a Ni-rich layered cathode (LiNi0.8Co0.15Al0.05O2) to enhance its electrochemical performance. The optimized sample exhibited a high discharge capacity of around 170 mA h/g after 200 cycles at 1C rate, with a capacity retention of over 81.1%. Postmortem analysis revealed that the SrTiO3-x coating not only alleviated the growth of internal resistance due to uncontrollable cathode-electrolyte interface evolution but also served as a lithium diffusion channel during prolonged cycling. This work presents a feasible strategy for improving the electrochemical performance of high-nickel content layered cathodes for next-generation LIBs.

Summary: Red phosphorus has been demonstrated for photocatalytic hydrogen evolution, but the P vacancy defects in red phosphorus have a significant influence on its photocatalytic performance. This study establishes the crucial relationships between the intrinsic P vacancy defects and the charge dynamics, and reveals the detrimental effect of deep charge trapping induced by P vacancies on the photocatalytic performance of red phosphorus. Oxygen doping in the P vacancy sites is demonstrated to be an effective strategy for eliminating the detrimental defect states and enhancing the photocatalytic performance of red phosphorus. This research provides a promising way to tune the physicochemical properties of red phosphorus and other elemental-based materials for various applications.

Summary: Photocatalysis is a highly promising technology for solving environmental problems. The g-C3N4 photocatalyst has drawn significant attention due to its stability, light response, low cost, and environmental-friendly properties. However, the pristine g-C3N4 suffers from recombination of charge carriers, lack of active sites, and limited visible light harvesting, resulting in unsatisfactory photocatalytic performance. Heterostructured C3N4 photocatalysts have emerged as a research focus in environmental fields, offering enhanced dissociation of electron-hole pairs, broader visible light response, and improved photoredox capability. The developments and strategies for constructing efficient C3N4-based heterostructures are critically reviewed, providing valuable insights for readers and inspiring new concepts in heterostructure engineering. Furthermore, the challenges and opportunities in fabricating large-scale and commercial heterostructured C3N4 photocatalysts are discussed for future directions in this field.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
