On heating, calcium reacts with hydrogen, halogens, boron, sulfur, carbon, and phosphorus.
These native elements are commonly divided into three groups namely, metals (platinum, iridium, osmium, iron, zinc, tin, gold, silver, copper, mercury, lead, chromium); semimetals (bismuth, antimony, arsenic, tellurium, selenium); and nonmetals (sulfur, carbon).
The original sulfur cathode exhibited a homogenous distribution of sulfur, carbon and pores.
In this aspect, rich in sulfur carbon of a relatively low surface was found as the most efficient formaldehyde adsorbent.
We have applied mixture design and response surface techniques to prepare visible light-active TiO2 photocatalysts codoped with sulfur, carbon, and tin oxide using titanium tetraisopropoxide (TTIP), tin(IV) chloride, and thiourea, respectively, as precursors.
Other peaks relevant to the oxidation process such as the peaks relating to the disulfide (450 550 cm−1), thiol (2500 2600 cm−1) or sulfur carbon groups (590 700 can1) cappeareas as very weak bands that may be masked by background noise [13, 14].
North Antelope Rochelle and the other vast strip mines cutting through the plains of Wyoming's Powder River Basin — whose low-sulfur carbon met standards imposed by the Clean Air Act — were the result.
More importantly, the cell shows negligible degradation in the sulfur-, carbon- and hydrocarbon-containing fuels.
Thus, YST holds the promise as anode material for SOFCs, especially in high concentration sulfur-, carbon- and hydrocarbon-containing fuels.
Wet ball-milling route is employed to prepare sulfur-carbon nanotubes composites.
This effect can be explained, by the sulfur-carbon doping of the TiO2 particles, providing extension of the light absorption to the visible range of the spectrum.
