Summary: Transition metal phosphides (TMPs) have attracted attention in electrocatalytic hydrogen production due to their multiple active sites and adjustable structures. However, the catalytic performance of pure TMPs in the hydrogen evolution reaction (HER) is not ideal. Atom doping engineering has the potential to enhance the kinetics of catalytic reactions by adjusting the electronic structure and Gibbs free energy. This review examines previous work on atom doping engineering, including the activity origin of doped TMPs, doping materials, methods, and the resulting HER properties.

Summary: Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is crucial for the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs) have been recognized as attractive HER catalytic materials due to their abundant reserves, unique structure, tunable composition, and high electronic conductivity. However, the HER activity of TMPs is still limited by various issues and performance bottlenecks. This review addresses these issues, provides explanations and solutions based on the origins of HER catalytic activity in TMPs, presents strategies to improve HER performance, and proposes critical scientific issues for constructing high-efficiency TMP-based electrocatalysts. Challenges and future directions for this research field, including the HER reaction process, catalytic mechanism research, TMP-based catalyst construction, and application expansion, are also discussed.

Summary: The current global demand for green H2 from water necessitates the use of an efficient and robust catalyst to reduce greenhouse gas emissions. Transition metal phosphide (TMP) based catalysts have emerged as viable alternatives to state-of-the-art Pt/C catalysts for the hydrogen evolution reaction (HER). However, further investigation is needed to assess the recent development and progress of TMP-based catalysts for HER, in order to encourage the development of efficient, robust, and durable catalysts. This review provides an overview of the recent research progress on TMPs for electrochemical HER, including nanostructure synthesis, integration with support materials, and hybrid structure synthesis. The review also discusses the fundamental aspects of HER kinetics, the effect of composition and pH on different types of TMPs, and the need for pre and post-analysis to evaluate the true identity of active sites and the durability of TMPs.

Summary: Designing robust binders is crucial for stabilizing Si anodes, but the current binders for Si nanoparticles are not suitable for low-cost Si micron-powders. Therefore, a novel binder design strategy is highly demanded. By coupling potassium tripolyphosphate (PTP) with alginic acid (Alg), a water-based network binder (c-PTP-Alg) with high mechanical resistance and homogenous texture has been developed. This binder greatly improves the electrochemical performance of micron-Si anodes.

Summary: A new metal-free O-doped and pyridine-grafted g-C3N4 (OCN/Py) was prepared and used to degrade tetracycline (TC) with peroxymonosulfate (PMS) as oxidant under visible light irradiation. Doping of O and graft of Py into CN framework could enhance the separation of photogenerated charge carriers, the adsorption of PMS and TC, as well as PMS activation. The OCN/Py-PMS* complex was formed and mediated electron transfer for degrading TC. 97.0% TC was degraded after 60 min visible light irradiation in the presence of 0.16 g L-1 OCN/Py and 0.5 mM PMS. The work provides an effective way to change CN structure for boosting TC degradation and gives deep insights for the relationship among photo-generated charge separation, PMS activation and TC degradation.

This study successfully constructed cationic and anionic vacancies in WO3 and modulated the concentration ratio via the addition of glucose. The moderate concentration ratio of W and O vacancies improved the electrode's active sites, electronic conductivity, electrostatic potential, and structural stability. Additionally, the O--O bonding induced by the moderate content of W vacancies facilitated Mg2+ diffusion and enhanced the electrode's specific capacity, rate capacity, and cycling life.

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.
