Platinum-complexed phosphorous-doped carbon nitride for electrocatalytic hydrogen evolution

Sustainable hydrogen gas production is critical for future fuel infrastructure. Here, a series of phosphorous-doped carbon nitride materials were synthesized by thermal annealing of urea and ammonium hexafluorophosphate, and platinum...

Organocatalytic Combinatorial Synthesis of Quinazoline, Quinoxaline and Bis(indolyl)methanes

Aim and Objective: An efficient and practical procedure for the synthesis of heterocyclic compounds such as quinazolines, quinoxalines and bis(indolyl)methanes was developed using 3,5-bis(trifluoromethyl) phenyl ammonium hexafluorophosphate (BFPHP) as a novel organocatalyst. Material and Method: All of the obtained products are known compounds and identified by IR, 1HNMR, 13CNMR and melting points. Results: Various products were obtained in good to excellent yields under reaction conditions. Conclusion: The BFPHP organocatalyst demonstrates a novel class of non-asymmetric organocatalysts, which has gained much attention in green chemistry.

Enhancing the efficiency of CsPbX3 (X = Cl, Br, I) nanocrystals via simultaneous surface peeling and surface passivation

A mechanism of simultaneous surface peeling and passivation by choosing an appropriate treatment time with ammonium hexafluorophosphate was verified to improve the PLQY of CsPbX3 (X = Cl, Br, I) PNCs covering the entire visible spectra effectively.
