Performance, Mechanism, and Kinetics of Fe(III)EDTA Reduction by Thiourea Dioxide

Energy & Fuels, 2019
Reducing Fe(III)EDTA into Fe(II)EDTA has a very remarkable significance for NO removal using Fe(II)EDTA solution. Here, the reductant thiourea dioxide (TD) was first served for reducing Fe(III)EDTA.

Facile synthesis of NiS2 nanoparticles ingrained in a sulfur-doped carbon nitride framework with enhanced visible light photocatalytic activity: two functional roles of thiourea

, 2018
A one-step, simple and low-cost strategy toward production of novel NiS2/S-doped g-C3N4 (NiS2/CNS) composites was successfully accomplished. The hybrid photocatalyst materials with different amounts of NiS2 nanoparticles (NPs) were successfully in situ ...
