To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.

The design of highly efficient photocatalysts to photoreduce nitrogen (N) to ammonia (NH) under mild conditions is extremely challenging. In this work, various molar ratio of molybdenum (Mo) is incorporated into BiOCl via a hydrothermal process. The resulting Mo-doped BiOCl exhibits remarkable solar-driven activity for N photo fixation without any scavengers or sacrificial agents.

This study explores the correlation of contaminants of emerging concern (CECs) in wastewater effluents using liquid chromatography (LC), supercritical fluid chromatography (SFC), and comprehensive two-dimensional gas chromatography (GC × GC) with derivatization, all coupled to high-resolution mass spectrometry (HRMS). Over 300 compounds, including frequently overlooked highly polar and nonpharmaceutical CECs, were identified. Monitoring programs mainly focus on reducing variability and assessing pollution in wastewater treatment plant (WWTP) effluents under dry weather conditions, often neglecting wet-weather discharges.

Anode-free lithium metal batteries are promising toward high-energy-density power sources with low-cost, but their practical applications are challenged by poor cycling stability and low rate capability. Herein, a shape change-free and lithium-free anode that well controls the reversible Li plating-stripping is reported, which is composed of a highly-ordered hollow ZnO matrix with a surface-coated lithium-phosphorus-oxynitride (LiPON) layer. The ZnO matrix supplies sufficient cavities and lithiophilic sites to facilitate uniform Li plating/stripping within the hollow cavity, while the LiPON layer maintains stable solid-electrolyte interphase from mechanical and electrochemical damage.

Chemical upcycling of plastic waste to produce green H has emerged as a promising avenue. Highly efficient and robust NiAlO catalysts with dual active nanocomposite (NiO-NiAlO) through a facile electronic configuration modulation strategy are synthesized for the decomposition-catalytic steam reforming (DCSR) of plastic wastes for enhancing H production while alleviating carbon deposition. Of these dual-active nanocomposite catalysts, NiAlO-800 presents the highest proportions of Ni cations and oxygen vacancies, contributing to the enhance structural stability and catalytic activity.
