A redox cycle between Ce4+ and Ce3+ is the elementary step in water gas shift (WGS) mechanism. Facilitating a +4 +3 of cerium enhanced formation oxygen vacancy which considered as dominate factor for developing WGS performance stability ceria material. Therefore, this work, we have tried to facilitate CeO 2 enrich activity. The reaction was carried out on Ni catalyst supported by Gd-doped (GDC)...

A new polyvinyl choloride (PVC) membrane sensor for cerium(III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensorexhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with aNernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7M. It has a fast response time (5 s) and can be used for two month...

The influence of Ni loading on Ce0.9La0.1O1.95-supported catalysts for CO2 reduction with hydrogen (reverse water gas shift reaction) is studied. samples are prepared by solution combustion synthesis (SCS), leading to materials high thermal resistance, purity, and crystallinity, consisting metallic nickel nanoparticles supported La-doped ceria. study the ferromagnetic Curie temperature (TC) mag...

When Rhizobium etli CE3 was grown in the presence of Phaseolus vulgaris seed extracts containing anthocyanins, its lipopolysaccharide (LPS) sugar composition was changed in two ways: greatly decreased content of what is normally the terminal residue of the LPS, di-O-methylfucose, and a doubling of the 2-O-methylation of other fucose residues in the LPS O antigen. R. etli strain CE395 was isolat...

Lacking an effective strategy to simultaneously address the challenges of quantum efficiency, luminescence intensity and thermal stability has become key bottleneck for further development large-scale application solid-state lighting technology. Herein, inspired by defect-engineering used in photoelectrocatalytic photovoltaic materials, we acted a diametrically opposite way unprecedentedly prop...
