Summary: The combination of the dual sites of hydrogen evolution reaction (HER) and ethanol oxidation reaction (EOR) into a single electrocatalyst is essential for energy-saving hydrogen generation. However, the challenges of fewer active sites hinder such combination for practical applications. In this work, a heterogeneous nanostructure of ZnSe-MnSe embedded in nitrogen-doped carbon was prepared, which showed superior HER and EOR performances due to the regulated electronic states and optimized adsorption properties.

Summary: The ethanol surface reaction over CeO2 nanooctahedra and nanocubes was studied using infrared spectroscopy, mass spectrometry, and density functional theory calculations. The results show that the production of H2 is 2.4 times higher on CeO2-NC than on CeO2-NO, which can be explained by the different types of adsorbed ethoxy species on the different surfaces. The study also reveals the different pathways for H2 formation on the two surfaces of CeO2 nanoshapes.

Summary: Ethanol steam reforming (ESR) is a promising technology for hydrogen production, and the study focuses on the influence of cobalt loading and ESR conditions on H2 selectivity and catalytic stability. Ni-Co/Al2O3 (5 wt% Co) catalyst exhibited the best performance with small metal crystallite size, high surface area, and high catalytic activity. Optimal conditions for 100% ethanol conversion and maximum H2 selectivity were found to be 600°C, 0.05 L/gcat.h, and S:C molar ratio of 12:1. The Ni-Co interaction was found to affect the catalytic activity, and the stability test showed minimal coke deposition.

Summary: The study of hydrogen energy is gaining attention for its effectiveness in achieving net zero and environmental sustainability. Bioethanol is a carbon-neutral fuel for hydrogen production and has potential as a sustainable energy source. This research assesses different routes for ethanol reforming and evaluates the impact of catalyst physicochemistry and experimental parameters on hydrogen production. The findings show that non-noble metals like Co and Ni are more reactive than noble metals in ethanol steam reforming, while the sequence of hydrogen selectivity differs in autothermal reforming of ethanol. The review highlights the importance of sustainable hydrogen production and decarbonization in reaching the net zero target.

Summary: This study presents the synthesis of cobalt-iron oxide nanosheets with controlled amounts of SO42- anionic groups, which exhibit excellent performance in the electrochemical oxygen evolution reaction (OER). The synthesis involves the use of a cobalt-based zeolitic imidazolate framework as a template and a source of iron and sulfate. Through a diffusion-controlled process, the structure of the framework is etched, forming porous assemblies of nanosheets. Iron ions partially replace cobalt, and sulfate ions are anchored on the material surface. The optimized material demonstrates outstanding OER activity, with a low overpotential and high stability.

Summary: Selective electrochemical upgrading of CO2 to multicarbon (C2+) products requires a C-C coupling process involving Cu oxidation states. This study reveals the critical role of Cu+ in promoting C-C coupling through coordination with a CO intermediate. Cu+ is dynamically stabilized by the presence of iodide (I-) in HCO3- electrolytes, leading to an increased C2+ Faradaic efficiency. Introducing CuI into I--containing HCO3- electrolytes enables a higher C2+ selectivity for direct CO electroreduction.

Summary: The non-covalent donor-acceptor structure composed of ZnTCPP and C60-EDA showed improved separation of photogenerated excitons, resulting in enhanced photocatalytic performance for H2 evolution. The efficient electron transfer channel between ZnTCPP and C60-EDA contributed to the charge separation and faster migration of charge-carriers. The photocatalytic activity of ZnTCPP/C60-EDA for H2 evolution was 113.5 mu mol h-1, which was 3.9 times higher than that of pure ZnTCPP. This work provides valuable insights into non-covalent D-A construction for enhanced photocatalysis.

Summary: Using aberration-corrected scanning transmission electron microscopy, we observed the coexistence of the antiferroelectric and ferrielectric phases in PbZrO3. The ferrielectric phase, with a dipole arrangement of 4,14, appears as translational boundaries at room temperature. The dual nature of the ferrielectric phase poses symmetry constraints on its growth, which are overcome by the sideways motion of boundaries forming stripe domains within the antiferroelectric matrix.

Summary: In plasmon-based devices, there is a tradeoff between the superb performance of Ag and the stability of Au in the choice of metal for the nanostructures. This study successfully created hybrid Au-Ag nanoislands with diverse morphology and tunable plasmon resonance using a large-area nanofabrication procedure. The Au-Ag nanoislands exhibited silver-like plasmonic properties and stability over a period of at least 5 months, with significantly higher SERS efficiency than Ag nanoislands. The study also provided insights for future sensor design and showed great potential for biomedicine sensing.

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.
