Urea electrolysis can convert urea from urea‐rich wastewater to hydrogen for environmental protection and sustainable energy production. However, the sluggish kinetics of urea oxidation reaction (UOR) requires valence‐variable sites that are generally active at high anodic overpotentials. Herein, a robust ceramic coating is constructed with coupled tungsten nitride (WN)/nickel carbide (Ni3C) nanoparticles to achieve valence‐stable catalytic sites with outstanding UOR performance. Various characterization results indicate strong interfacial electron transfer from WN to Ni3C in coupled nanoparticles, which enables reservation of Ni2+ sites without self‐oxidation during UOR, quite distinct from the kinetically slow Ni3+OOH‐catalyzed UOR pathway. Theoretical calculations show that the coupled effect in WN/Ni3C leads to enhanced electron transfer from catalytic sites to adsorbed urea, and W sites are thermodynamically favorable for UOR. This efficiently lowers the barrier of rate‐determining step (RDS: *CO‐N2 → *CO·OH), thus enabling fast UOR kinetics and a low potential of 1.336 V at 100 mA cm−2, which identifies this ceramic coating as one of the best UOR electrocatalysts. This work opens a new avenue for design of stable and active sites in ceramics coatings toward advanced electrocatalytic applications.

“…Titanates-based transition metal photocatalyst (e.g., NiTiO 3 , CoTiO 3 , and Co 0.5 Ni 0.5 TiO 3 ) are reported to achieve 42−98% EtP degradation in 300 min. 63 The high crystallinity and smaller particle size allow enhanced dispersion, absorption of exciting light, and extended production of e − −h + pairs. Nonetheless, the poor mineralization efficiency under visible light depicts that UV radiations played a significant role in EtP degradation.…”

The increased consumption of parabens and associated health hazards has necessitated the development of water treatment technologies capable of removing parabens to desired levels. Among the various available treatment options, catalytic degradation has the advantages of faster reaction kinetics, increased reactive species formation, and no sludge disposal problem. Accordingly, an overview of recent advances in catalytic systems briefing removal, mineralization, and performance comparison between catalysts is essential to scale up and transfer lab-scale results to real-scale applications. The current review highlights the superiority of photocatalysis, Fenton’s, persulfate, and ozonation/catalytic ozonation systems to eliminate parabens. The performance evaluation and economic feasibility of catalytic treatment systems were identified using mathematical models. Additionally, density functional theory calculations were carried out to assess the fundamental mechanism associated with paraben degradation by TiO2 and to develop a molecular-level understanding of synthesizing catalysts that can effectively degrade parabens. In a nutshell, this review acts as a roadmap to show the feasibility of catalytic treatment technologies to eliminate parabens from the water environment.

Recent Advances in Endocrine Disrupting Compounds Degradation through Metal Oxide-Based Nanomaterials

Endocrine Disrupting Compounds (EDCs) comprise a class of natural or synthetic molecules and groups of substances which are considered as emerging contaminants due to their toxicity and danger for the ecosystems, including human health. Nowadays, the presence of EDCs in water and wastewater has become a global problem, which is challenging the scientific community to address the development and application of effective strategies for their removal from the environment. Particularly, catalytic and photocatalytic degradation processes employing nanostructured materials based on metal oxides, mainly acting through the generation of reactive oxygen species, are widely explored to eradicate EDCs from water. In this review, we report the recent advances described by the major publications in recent years and focused on the degradation processes of several classes of EDCs, such as plastic components and additives, agricultural chemicals, pharmaceuticals, and personal care products, which were realized by using novel metal oxide-based nanomaterials. A variety of doped, hybrid, composite and heterostructured semiconductors were reported, whose performances are influenced by their chemical, structural as well as morphological features. Along with photocatalysis, alternative heterogeneous advanced oxidation processes are in development, and their combination may be a promising way toward industrial scale application.
