A novel magnetic CuFeAl-LDO catalyst for efficient degradation of tetrabromobisphenol a in water

Xiangting Hou et al.

Summary: The magnetic Cu1Fe0.5Al0.5-LDO catalyst successfully degraded TBBPA by activating PMS system with high degradation rate under optimized conditions, showing stability and reproducibility due to the presence of active species. Toxicity assessment indicated that the Cu1Fe0.5Al0.5-LDO/PMS system effectively reduced the harm and risk of TBBPA to the overall environment. These findings suggest a possible novel approach for the degradation of brominated phenolic organic pollutants in actual water using the Cu1Fe0.5Al0.5-LDO/PMS system.

A novel highly active catalyst form CuFeMg layered double oxides for the selective catalytic reduction of NO by CO

Jun Liu et al.

Summary: A series of CuxFeMg4-x-LDO and Cu/FeMg2.8-LDO catalysts were prepared by calcination of CuFeMg layered double hydroxide (LDH) for CO-SCR reaction. The Cu1.2FeMg2.8-LDO catalyst exhibited the highest CO-SCR activity, with 100% NO conversion at 225-600 degrees C and a space velocity of 60000 mL.g(-1).h(-1). The CuxFeMg4-x-LDO composite metal oxide, formed by topotactic transformation, promotes the dispersion of CuO species and the generation of CuzMg1-zFe2O4 spinel phase and reactive oxygen species. The catalyst also shows high H-2 consumption and more surface adsorbed oxygen, improving the redox capacity. The presence of Cu+-CO/Fe2+-CO species and relatively low activation energy contribute to the better catalytic activity at low temperatures. The CO-SCR reaction over Cu1.2FeMg2.8-LDO catalysts follows the L-H mechanism at low temperatures and the E-R mechanism at high temperatures. This study provides insights for designing highly efficient catalysts for low temperature CO-SCR reaction.

Insights into high CO-SCR performance of CuCoAlO catalysts derived from LDH/MOFs composites and study of H2O/SO2 and alkali metal resistance

Yu Zhang et al.

Summary: This study successfully developed Cu and Zn modified CoAlO catalysts with improved denitration performance and anti-poisoning ability, showing great potential for practical applications at low temperatures. The synergistic interaction between Co and Cu contributes to the outstanding deNOx performance. This work provides a new strategy for the design and fabrication of low temperature CO-SCR catalysts.

Effects of phosphorus modification on the catalytic properties and performance of CuCeZr mixed metal catalyst for simultaneous removal of CO and NOx

Qi Liu et al.

Summary: Phosphorus-modified CuCeZr catalyst demonstrates high conversion rates for both CO and NOR, achieving up to 90% conversion at temperatures of 200-350 degrees Celsius. The modification balances the catalyst's redox ability and surface acidity, facilitating the suppression of NH3 over-oxidation during selective catalytic reduction (SCR) process. This work paves the way for simultaneous CO oxidation and NH3-SCR reactions on a single catalyst, offering a novel approach for synergistic control of flue gas pollutants.

Design Aspects of Doped CeO2 for Low-Temperature Catalytic CO Oxidation: Transient Kinetics and DFT Approach

Kyriaki Polychronopoulou et al.

Summary: Eliminating CO through oxidation over highly active and cost-effective catalysts is important for industrial and environmental processes. Doped CeO2 with transition metals was tested for CO oxidation, showing that Cu-Ce-O catalyst has the highest activity. The involvement of lattice oxygen species in the reaction and the effectiveness of different heteroatoms were investigated and quantified.
