Abstract Nitrate (NO 3–) pollution of water bodies is a serious environmental problem
worldwide. One of the major concerns about NO 3–contamination is the lack of cost-effective …

This study describes the synthesis of Nb 2 O 5 by three sol-gel methods to be used as a
catalyst in photocatalysis, catalytic ozonation and the synergistic effects of the two …

The electrochemical nitrate reduction to ammonia (NRA) has emerged as a promising and
environmentally friendly alternative to the fossil-intensive Haber-Bosch process. Single-atom …

Graphitic carbon nitride (GCN) is an optical semiconductor with excellent photoactivity under
visible light irradiation. It has been widely applied for organic micropollutant removal from …

Electrochemical nitrate reduction (E-NRR) powered by renewable electricity is a sustainable
method of converting toxic nitrate into benign products (N2) or value-added products (NH3) …

The development of macrostructured catalysts for remediation processes is a key step
towards the sustainability of multi-phase environmental systems, such as the catalytic …

Bimetallic catalysts applied for water treatment are highly susceptible to
deactivation/poisoning mainly when immobilized in macroscopic structures. Metal support …

A novel green and efficient synthesis methodology for carbon-coated macrostructured
catalysts was assessed. Sodium alginate was used as a dispersant to promote a suitable …

In this work, we study the effect of modifying the metal loading (0.5–1.5 wt.% Pd and 0.1–1
wt.% Sn or In), the impregnation order of noble or promoter metal (Pd–Sn or Sn–Pd), and the …

Growing concerns regarding the inefficient degradation of persistent pollutants, such as
ibuprofen, in water necessitate the development of advanced treatment methods. Nb 2 O 5 …
