Summary: In this study, a hierarchical dendritic Co3O4-SnO2 heterostructure was prepared via a sequential hydrothermal process for treating refractory organics. The size of the ultrathin SnO2 nanosheets can be controlled by the time of the secondary hydrothermal process. Ti/Co3O4-SnO2-168h showed a photoelectrocatalysis degradation rate of approximately 93.3% for a high dye concentrate, with good long-term cyclability and durability. The proposed type-II heterojunction between Co3O4 and SnO2 prevents carrier recombination and enhances the generation of active species.

Summary: Photoelectric catalytic oxidation (PEC) is a promising strategy for degrading antibiotic refractory pollutants. In this study, a flower-like Co3O4/CoO catalyst was constructed, and its PEC performance was investigated. The Co3O4/CoO catalyst showed a significantly higher removal rate of tetracycline (TC) compared to pure Co3O4 and CoO due to the establishment of an electric field and the synergistic effect between electrocatalytic and photocatalytic processes.

Summary: This work reports a facile two-step hydrothermal process for constructing a binary composite oxide system (1D/2D Co3O4/NiMnO3 core-shell heterostructure) based on Ostwald ripening effect. The formation of continuous and uniform interface between core and shell is the key factor in the heterogeneous nucleation process, which is supported by the homogeneous diffusion of Co element. The optimized Ti/Co3O4-NiMnO3-1.5 exhibits superior PEC performance for degrading reactive brilliant blue KN-R solution, attributed to the construction of the hollow core-shell heterostructure.

Summary: Designing a cost-effective and environmentally friendly heterogeneous structure is challenging in the photoelectrocatalytic (PEC) process for treating refractory organic wastewater. This study introduces a necklace-like alpha-MnO2@Co3O4 (MC) heterostructure, which integrates 1D alpha-MnO2 and Co3O4 with exposed (111) facets. The optimized MC-2 exhibits superior PEC performance with a removal rate of 88.44% for reactive brilliant blue KN-R and a long-term stability of 5000 s. The type-II heterojunction between alpha-MnO2 and Co3O4 effectively prevents carrier recombination and enhances the generation of h(+) and center dot O-2(-) species. This work provides valuable insights for the PEC degradation of KN-R and guides the development of heterogeneous materials for large-scale water purification applications with reduced costs.

Summary: In this study, Ag2Ox (3 wt%)-loaded ZnFe2O4 photocatalysts were synthesized for acetamiprid degradation, antibacterial, antioxidant, and toxicity assay by co-precipitation and incipient wet impregnation approach. The prepared photocatalysts were characterized and the optimum Ag2Ox (3 wt%)-loaded ZnFe2O4 photocatalysts demonstrated higher degradation efficiency for acetamiprid under sunlight irradiation. They also showed improved antioxidant and antibacterial activity compared to blank and bare ZnFe2O4 nanomaterials. The enhanced catalytic efficiency can be attributed to the loaded Ag2Ox NPs on ZnFe2O4 nanomaterials.

Summary: Graphite-based materials have gained significant attention and rapid development in the ore industry due to their structure and excellent conductivity. However, there is still a lack of a complete industrial chain from raw materials to commercial products. To accelerate the industrialization process, optimizing the beneficiation process is crucial for improving the valuable minerals by addressing the differences in their physical and chemical properties. This review focuses on the standard beneficiation methods and presents a comprehensive flotation process for high-quality graphite flake, and also discusses the energy storage applications of graphite-based materials.

Summary: In recent years, the use of dyes and nanoparticles has increased significantly, posing a serious health risk to ecosystems. This study fabricated TiO2 and g-C3N4 nanosheets through co-precipitation and thermal polymerization techniques, respectively. The g-CN-TiO2 nanocomposite with different weight percentages exhibited enhanced photocatalytic performance against methylene blue (MB) dye under UV-visible light illumination. The optimized g-CN-TiO2 nanocomposite (3:1) showed the highest catalytic efficiency due to the low amount of TiO2 nanoparticles deposited on g-CN nanosheets and the development of a Z-scheme system between TiO2 and g-CN.

Summary: Pseudocapacitors, achieved through surface redox reactions, have higher capacitances than electrical double-layer capacitors. However, balancing the capacitance and kinetics of the positive and negative electrodes is necessary for full energy release. In this study, A-MMO and N,P-VOx, designed with comparable capacitances, exhibited high rates due to the presence of surface cation vacancies and amphoteric N and P species. The results reveal the critical roles of CVAs and amphoteric species in regulating the electronic structure and electrochemical activity of pseudocapacitive materials, leading to the development of a high-energy density and mechanically flexible A-MMO//N,P-VOx pseudocapacitor.

Summary: Chromium doped CdO films were prepared by chemical spray deposition and characterized for their optical, electrical, structural, and microstructural properties. The films exhibited cubic crystal structure with growth along the (111) plane. Uniform distribution of grains and varied surface roughness were observed based on atomic force microscopy analysis. The films showed high optical transmittance (>75%) in the visible-near infrared region, with a maximum band gap of 2.35 eV for 1.0 wt% Cr-doping. Electrical measurements confirmed degeneracy nature and n-type semi-conductivity, with higher Cr-dopant percentage leading to increased carrier density, carrier mobility, and dc-conductivity. A remarkable response to formaldehyde gas (74.39%) was observed for 0.75 wt% Cr-doping.

Summary: A general strategy for fabricating hollow binary oxides heterostructures (Co3O4-8-MnO2 and Co3O4-SnO2) utilizing Ostwald ripening is revealed. The structural evolution of hollow Co3O4-8-MnO2 nano-network is systematically explored, and the origin of hollow binary oxides is identified as the interfaces acting as landing sites. The optimized Co3O4-8-MnO2-48 exhibits superior PEC degradation efficiency and durability, attributed to the massive hollow structures' vast surface area and the enhanced interaction between the catalyst's surface and active species.

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.
