Paired electrochemical N−N coupling: potential-mediated selective electrosynthesis of azoxy aromatics plus 5,5′-azotetrazolate energetic materials in aqueous media

Azoxy aromatics are extensively utilized in materials science, pharmaceuticals, and synthetic chemistry, but their controlled and environmentally-friendly synthesis has rarely been reported. Herein, a potential-mediated electrosynthesis strategy was developed by selective reduction of 4-nitrobenzyl alcohol (4-NBA) on Mn-doped Ni2P nanosheets@nickel foam (Mn-Ni2P/NF), enabling efficient N−N coupling to produce Azoxy with 100% selectivity at potentials of −0.6 to −0.8 V (vs. Hg/HgO). At more cathodic potentials, the product was converted to Azo and then to amino aromatics due to facilitated nitrogen hydrogenation. Additionally, the organic energetic material, 5,5′-azotetrazolate, was also synthesized by anodic N−N coupling of 5-amino-1H-tetrazole on Cu(OH)2 nanowires@copper foam (Cu(OH)2/CF). It bypassed harsh conditions (strong oxidants, high temperature, by-products separation, etc.) for the traditional synthesis of this class of materials. As a consequence, a two-electrode electrolyzer Cu(OH)2/CF||Mn-Ni2P/NF was assembled, allowing paired electrochemical N−N coupling into Azoxy and 5,5′-azotetrazolate. It achieves a current density of 50 mA cm−2 at a voltage of only 1.19 V, 880 mV lower than the competitive water splitting. This electrolyzer can be efficiently driven by a 1.2 V solar panel with excellent yield and selectivity, paving the way for green synthesis of valuable chemicals through electrochemical N−N coupling strategies. © 2025 Science Press

Biological treatment technologies (such as anaerobic digestion, composting, and insect farming) have been extensively employed to handle various degradable organic wastes. However, the inherent complexity and instability of biological treatment processes adversely affect the production of renewable energy and nutrient-rich products. To ensure stable processes and consistent product quality, researchers have invested heavily in control strategies for biological treatment, with machine learning (ML) recently proving effective in optimizing treatment, predicting parameters, detecting disturbances, and enabling real-time monitoring. This review critically assesses the application of ML in biological treatment, providing an in-depth evaluation of key algorithms. This study reveals that artificial neural networks, tree-based models, support vector machines, and genetic algorithms are the leading algorithms in biological treatment. A thorough investigation of the applications of ML in anaerobic digestion, composting, and insect farming underscores its remarkable capacity to predict products, optimize processes, perform real-time monitoring, and mitigate pollution emissions. Furthermore, this review outlines the challenges and prospects encountered in applying ML to biological treatment, highlighting crucial directions for future research in this area. © 2024 The Author(s)

While oxygen vacancy (Ov) in single semiconductor photocatalysts have been widely studied, the investigation and deep understanding of electron transfer and intrinsic mechanisms of Ov in heterojunction photocatalysts, particularly S-scheme heterojunctions, remain limited. In this study, we designed and constructed novel oxygen vacancy-rich Ov-Bi4O7/Bi3.64Mo0.36O6.55 (MOB) S-scheme heterojunction catalysts. These catalysts couple oxygen vacancy-rich Bi4O7 with Bi3.64Mo0.36O6.55 (BMO) to facilitate heterojunction interfacial charge transfer and create oxygen vacancy-rich active centers. The optimized MOB-32 heterojunction degraded tetracycline (TC) by 97.6% under light irradiation. The introduction of Ov optimized the microenvironment and local electronic structure in the S-scheme heterojunction. Femtosecond transient absorption spectroscopy (Fs-TAS) reveals that Ov introduce additional charge transport pathways, thereby enhancing charge separation efficiency. This study offers new insights into the dynamics of photogenerated carriers at oxygen vacancy-modulated heterogeneous interfaces and aids in the design of efficient S-scheme photocatalysts. © 2024, The Authors.

Neglected Methane Production and Toxicity Risk in Low-Frequency Ultrasound for controlling Harmful Algal Blooms

Algal blooms are regarded as a significant source of CH4 emissions. Ultrasound has been gradually employed as a fast and efficient algae removal technology in recent years. However, the changes in water environment and potential ecological effects caused by ultrasonic algae removal are not fully clear. Here, a 40-day microcosm study was performed to simulate the collapse of Microcystis aeruginosa blooms after ultrasonic treatment. The results showed that low-frequency ultrasound at 29.4 kHz for 15 min removed 33.49% of M. aeruginosa and contributed to the destruction of cell structure, but it intensified the leakage of intracellular algal organic matter and microcystins. The accelerated collapse of M. aeruginosa blooms after ultrasonication promoted the rapid formation of anaerobic and reductive methanogenesis conditions, and elevated dissolved organic carbon content. Moreover, the release of labile organics, including tyrosine, tryptophan, protein-like compositions, and aromatic proteins, was facilitated by the collapse of M. aeruginosa blooms after ultrasonic treatment, and they supported the growth of anaerobic fermentation bacteria and hydrogenotrophic Methanobacteriales. This was also demonstrated by the increase in methyl-coenzyme M reductase (mcrA) genes in sonicated algae added treatments at the end of incubation. Finally, the CH4 production in sonicated algae added treatments was 1.43-fold higher than that in non-sonicated algae added treatments. These observations suggested that ultrasound for algal bloom control potentially increased the toxicity of treated water and its greenhouse gas emissions. This study can provide new insights and guidance to evaluate environmental effects of ultrasonic algae removal. © 2023, The Authors. All rights reserved.
