Nanoscale Zero-Valent Iron (nZVI) for Heavy Metal Wastewater Treatment: A Perspective

Engineering, 2023
Industries such as non-ferrous metal smelting discharge billions of gallons of highly toxic heavy metal wastewater (HMW) worldwide annually, posing a severe challenge to conventional wastewater treatment plants and harming the environment. HMW is traditionally treated via chemical precipitation using lime, caustic, or sulfide, but the effluents do not ...

Cost-Effective Synthesis of Fe₅C₂ Catalyst From Nanosized Zero-Valent Iron to Achieve Efficient Photothermocatalytic CO Hydrogenation to Light Olefins. [PDF]

Adv Sci (Weinh)
The Fe5C2 catalyst is synthesized from nanosized zero‐valent iron, through combining a ball‐milling with wet‐chemical carburization approach, which resulted in a 76.8% reduction in costs compared with using Fe2(CO)9 as iron source. The obtained low‐cost Fe5C2 catalyst delivered a high light olefins selectivity of 54.2% for CO hydrogenation under light ...
