Designing reasonable methods for synthesizing efficient, inexpensive, and stable electrocatalysts for water splitting is urgently needed. In this study, we construct Al-FeCoP nanosheet array on nickel foam (Al-FeCoP/NF) with superhydrophilic/superaerophobic properties. The superhydrophilic and underwater superaerophobic surface accelerate the electrolyte penetration and bubble dissipation, thereby taking the edge off the “bubble shielding effect”. The electronic structure of the electrocatalyst is tuned through heteroatom doping and phosphorization, which effectively enhances the conductivity of the catalyst. Strikingly, the resulting Al-FeCoP/NF electrode shows remarkable activity in alkaline media, which only requires an overpotential of 121 mV and 215 mV at 10 mA cm⁻² for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively. When applied for overall water splitting, the assembled two-electrode electrolyzer only needs a low voltage of 1.56 V to afford a current density of 10 mA cm⁻² and can maintain over 100 h without the obvious activity attenuation, which enhances the overall catalytic activity and represents superior long-term stability. In addition, the abundant wind and solar energy resources are employed to generate electricity directly, which is subsequently convert into green hydrogen by the water electrolysis in laboratory conditions. This work provides a new idea for the manufacture of low-cost, high-activity bifunctional transition-metal phosphide electrocatalyst by element doping for green hydrogen production.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"68 ","pages":"Article 106302"},"PeriodicalIF":6.3,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142442655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheles, addressing the limited light-harvesting spectrum of TiO₂ is crucial for practical applications. Herein, we propose a novel approach combining electronic enhancement through elemental doping and a hierarchical multi-level configuration under Z-scheme heterojunction to achieve remarkable photocatalytic activity. Using the alcohol-assisted sol-gel method, we incorporated bismuth atoms into the TiO₂ lattice to form (3)Bi-TO nanoparticles. While the hierarchical mesoporous texture provided (3)Bi-TO with a large S_BET (83 m²/g), the Bi incorporation conferred various defects and mid-gaps to improve light-harvesting and promote charge carrier separation. These were then encapsulated onto the exterior shell of alkoxide-based CuCo₂S₄ (YS-CCS) yolk-shell structures using a facile isoelectric point-mediated annealing technique, creating a Z-scheme YS-CCS@(3)Bi-TO yolk-in-double-shell architecture. The yolk-in-double-shelled YS-CCS@(3)Bi-TO heterojunction simultaneously enhanced light-harvesting, improved photon utilization, prolonged charge carrier lifetime, and advanced conductivity, as indicated by the UV–vis diffuse reflectance spectra (UV–Vis DRS), photoluminescence (PL), electrochemical impedance spectroscopy (EIS), and transient photocurrent. Upon optimizing the mass-loading of YS-CCS (40 wt%) and operational parameters (pH: 5, catalyst dosage: 1.0 g/L, and levofloxacin (LFC) concentration: 50 mg/L), the YS-CCS@(3)Bi-TO exhibited remarkable photocatalytic performance in total LFC photodegradation, which was 29.9, 4.7, and 11.3 folds kinetically higher than that of the YS-CCS and (3)Bi-TO, and Bi-free TO, respectively. The robustness of YS-CCS@(3)Bi-TO was demonstrated by sustained efficiency over six consecutive cycles, negligible metal leaching, and confirmed stability through XRD analysis. Additionally, its outstanding performance in long-time LFC mineralization over 5 h and real wastewater treatment over 6 h demonstrated a successful catalyst design with potential industrial applications. Finally, this design and strategy hold promises for developing nanomaterials with geometrical configuration and electronic properties in synergy for enhanced photocatalytic activity.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"68 ","pages":"Article 106247"},"PeriodicalIF":6.3,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142437732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the interactions among these metal(loid)s during adsorption on G-nZVI/WSB and their corresponding mechanisms remain unclear, we conducted a series of batch experiments coupled with characterization techniques.

This work investigates the effects of three commonly used phosphonate antiscalants, namely ATMP (aminotris (methylenephosphonic acid)), HEDP (1-hydroxyethylidene-1, 1-bis (phosphonic acid)), and PBTC (2-phosphonobutane-1, 2, 4-tricarboxylic acid), on the permeation and desalination performances of RO membranes.

However, the inhibitors may interact with the membrane surface and alter its properties, significantly affecting membrane performance. Excessive addition of antiscalants increases membrane contamination and deviates membrane flux from optimal levels. Furthermore, adding phosphonate inhibitors significantly affects the membrane retention efficiency of inorganic salt components and the extent to which the membrane retains organic wastewater components.
