Selective catalytic reduction of NOx using NH3 or hydrocarbons (NH3-SCR or HC-SCR) in
oxygen-rich exhaust from diesel engines remains a major challenge in environmental …

Iron oxide with different crystal phases (α-and γ-Fe2O3) has been applied to electrode
coatings and been demonstrated to ultrasensitive and selective electrochemical sensing …

The presence of heavy metal ions in water is an environmental issue derived mainly from
industrial and mineral contamination. Metal ions such as Cd (II), Pb (II), Hg (II), or As (III) are …

Abstract Novel Ca-doped FeO x hollow microspheres were successfully prepared using
carbon microspheres as templates. The as-prepared catalysts were characterized by FAAS …

Valorization of residual materials in the development of catalytic materials has an appealing
potential from the perspective of a sustainable development. For the first time, Fe/Mg …

Modulating the shape and crystal-phase of nano-sized iron-oxide particles play an essential
role in the design of highly efficient heterogeneous catalysts. Iron oxides usually present as …

Novel Cu–ZnO–ZrO2/UGSO catalysts for CO2 hydrogenation to methanol were developed
using a metallurgical residue (UGSO) as the catalytic support, with special focus on …
