Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Fe‐Free Photocatalysis‐Self‐Fenton System for Ultraefficient Water Purification Enabled by Carbon Nitride With Strong Built‐in Electric Field

open access: yesEcoEnergy, EarlyView.
This study reports a photocatalytic H₂O₂ production rate of 14.9 mmol g⁻¹ h⁻¹, representing a 22.2‐fold enhancement. Additionally, the Fe‐free PSFs achieved complete degradation of 100 mg·L⁻¹ tetracycline within 10 min across a wide pH range. ABSTRACT Photocatalytic‐self‐Fenton system (PSFs) hold great promise for water purification through in situ ...
