By a News Reporter-Staff News Editor at Nanotechnology Business Journal -- Current study results on Urea have been published. According to news reporting out of Fuzhou, People's Republic of China, by VerticalNews editors, research stated, "Phenylurea has been integrated into the traditional polymerization route of carbon nitride (CN) precursors (e.g., urea, thiourea, dicyandiamide, and ammonium thiocyanide) in a facile one-pot approach, to modify the chemical composition, electronic structure, and catalytic performance of graphitic CN (g-CN). Results revealed that the co-polymerization of phenylurea with urea dramatically modifies the optical and electronic properties of g-CN, leading to a remarkable improvement by a factor of 9 in the photocatalytic activity of g-CN (when coupled with Pt as a co-catalyst) in an assay of hydrogen evolution reaction, while still keeping a high catalytic stability during pre-longed operations."
Our news journalists obtained a quote from the research from Fuzhou University, "The active catalyst is eventually a hybrid organocatalyst that is a heterogeneous Pt catalyst supported on a urea-based polymer. The promotional effect of phenylurea as the co-monomer for urea on the activity and stability of Pt/g-CN-could be related to the-extension-of delocalized pi-conjugated system of CN heterocycles, as a result of the fusion of phenyl motifs in the CN framework. The thus created surface dyadic structure favors the separation and migration of charge-carriers photoexcited upon light illumination."
According to the news editors, the research concluded: "This work highlights a wide accessibility of chemical protocols for the design and synthesis of functional CN photocatalysts at molecular levels by applying suitable CN precursors and co-monomers."
