摘要
Rapid and convenient syntheses of ultra-small gold nanoparticles (AuNPs) utilizing a novel heteroleptic dipyrrin complex with dual functionality have been described. The AuNPs immobilized on GO led to partial reduction of GO to form AuNPs/prGO and reduce Cr(VI) to Cr(III) in the presence of HCOOH with the best performance achieved from AuNPs@prGO500.
