Unraveling the Mechanism for H2O2 Photogeneration on Polymeric Carbon Nitride with Alkali Metal Modification

نویسندگان

چکیده

K and Na have been widely used in photocatalytic H2O2 production. However, Rb Cs rarely studied for their potentials. In addition, the mechanism regulating production from different alkali metal (M)-modified polymeric carbon nitride (PCN) is still unknown. Therefore, M-doped PCN was fabricated using thermal copolymerization presence of Li, Na, K, Rb, or Cs. The activity CN-M enhanced by increase metallic character metals. CN-Cs’s not optimal even though it has strongest character. A stronger anticipated to yield Lewis acidic sites. Although ethanol can be adsorbed activated at strong sites, also these which speeds up degradation. CN-Rb—with its acceptable character, excellent oxygen adsorption capacity, reduced degradation—has best yield.

Transport properties of alkali-metal-doped single-wall carbon nanotubes

We report in situ measurements of four-probe dc resistance ~R! and thermopower ~S! of Csand K-doped single-wall carbon nanotube ~SWNT! mats as a function of a doping and temperature ~T!. With increasing dopant exposure, the mat resistance has been found to first decrease and then increase, exhibiting a minimum for optimal Cs doping. In contrast, for K doping, the mat resistance decreased monoto...
