Oxygen reduction reactionIron-cobalt alloyCarbon nanotubeSulfur dopingCharge transferSulfur- and nitrogen-codoped peapod-like carbon nanotubes are facilely prepared via pyrolyzing Fe- and Co-containing Prussian blue analogues supported on trithiocyanuric acid. Combined studies with X-ray diffraction, X-...
In relative to the single metal oxide-based oxygen carrier (OC), combined OC owned superiority for CLC of coal. In this research, combined NiFe2O4 OC was synthesized using sol–gel combustion synthesis method, and its reaction with a typical Chinese high-sulfur coal as Liuzhi (LZ) coal was ...
(−43 °C to 45 °C) were obtained, and they have variable mechanical properties, some of them are flexible and elastic, and some of them are stiff and relatively strong, which can be accurately controlled by chain length of linear segment of crosslinker combined with molar ration of...
Here, a stream of finely divided oxygen-containing gas is combined under agitation with the liquid sulfur to reduce residual sulfide/polysulfide concentration. Unfortunately, while such methods is at least conceptually effective, significant material and complexity is required. Similar problems are ...

The excellent electrochemical performances came from the unique porous structure and oxygen-containing functional groups of DPC. These properties combined physical and chemical methods to anchor polysulfides and further enhance the electrochemical performance. This study has great significance in terms of ...
The invention provides an energy-saving combined ore dressing process for high-oxidation and high-bonding oxygen and sulfur mixed copper ore. The process comprises the steps of raw ore treatment, preparation of leaching solution, stirring and leaching, dynamic soaking selection, solid-liquid separation...
The most probable explanation for this result would be the improper use of the Natelson Microgas Analyzer which was used to analyze the dissolved oxygen in the water. With this complete lack of precision in the oxygen data, it was decided that no analysis would be conducted with it, and ...
