A facile one-step green synthesis of stable gold nanoparticles (AuNPs) has been described using chloroauric acid (HAuCl4) and the leaf extract Lantana camara Linn (Verbenaceae family) at room temperature. The enriched in various types plant secondary metabolites is highly efficient for reduction chloroaurate ions into metallic stabilizes synthesized AuNPs without any additional stabilizing or capping agents. Detailed characterizations were carried out by surface plasmon resonance...
A low-cost, platinum-free electrocatalyst for hydrogen (H2) generation via the water splitting reaction holds great promise to meet demand of clean and sustainable energy sources. Recent studies are mainly concerned with semiconducting materials like sulfides, selenides, phosphides different transition metals as electrocatalysts. Doping within host matrix is a good strategy improve electrocatalytic activity material. However, this largely depends on nature dopant metal its well. To exploit...
The charge transfer effect at the graphene/transition metal interface has been studied extensively during last few years; however, experimental results are very poor. In present work, a Co atom capped with porphyrin is attached on graphene surface to realize induced magnetic properties arising due interface. Ferromagnetic ordering fairly large coercivity (516 Oe) observed as result of this magnetism in presence transition surface. Temperature dependent magnetotransport also investigated...
Transition-metal-based metal–organic frameworks (MOFs) have received great interest for the development of low cost, platinum-free, non-precious water splitting electrocatalysts hydrogen generation to resolve energy crisis.
An unprecedented p-TsOH and MsOH-catalyzed construction of valuable isoindolo/pyrido/pyrrolo-quinolinediones isoindolo-indolones is demonstrated through annulation reactions cyclic anhydrides or o-formylbenzoates with o-alkynylanilines. The metal-free Bro̷nsted acid-mediated new [5+1] [4+1] fused-cyclization an operationally simple, highly regioselective, atom economical, high yielding, sustainable, catalytically efficient approach.
In this work, a novel soluble and air-stable electron acceptor containing perylenediimide moiety named ANTPABA-PDI was designed synthesized with band gap 1.78eV that used as non-fullerene material. possess not only good solubility but also much lower LUMO (lowest unoccupied molecular orbital) energy level. Furthermore, its excellent capability supported by density functional theory calculation which validates the experimental observations. Inverted organic solar cell has been fabricated...
Unprecedented metal-free cyclization catalysis reactions are developed in a highly regioselective fashion to synthesize 3-amino-4-benzoyl biphenyls and arylacridones with high atom economy. Catalytic K2CO3 is utilized as the only reagent for unusual rapid dual C–C-coupled between β-keto enamines cinnamaldehydes furnish functionalized biphenyls. Its C(sp2)–H C–N bond-forming was performed situ using molecular I2 catalyst valuable arylacridones. Plausible mechanisms new predicted by conducting...
