Herein, a site-selec.ive paired elec.roc.emic.l c.H oxidation of func.ionalized alkyl arenes promoted by nic.el c.talyst is disc.osed. A Ni(Ⅱ)-dioxygen spec.es formed in situ effic.ently enable the oxidation proc.ss under mild c.nditions with a broad substrate sc.pe with exc.llent func.ional group c.mpatibilities,suc. as free c.rboxylic.ac.d, aldehyde, halogen(inc.uding aryl iodide), amide and amino ac.d. The use of the nic.el c.talyst in c.mbination with water provides a safe, green and ec.nomic.l method for oxidation of a range of molec.les varying in c.mplexity and drug derivatives, demonstrating its potential applic.tion in organic.synthesis and the pharmac.utic.l industry. reac.ion outc.mes and mec.anistic.studies revealed the key role of the in situ Ni(Ⅱ)-dioxygen spec.es for the subsequent oxidation of c.sp^(3))–H bonds,and short-lived reac.ive intermediates(aryl radic.l c.tion) was rapidly c.ptured by the c.mbination of a bipolar ultramic.oelec.rode(BUME) with nano-elec.rospray ionization mass spec.rometry.

Plasma-exfoliated g-c.(3)N_(4) with oxygen doping: tailoring photoc.talytic.properties

Heteroatom doping and defec. engineering have been proposed as effec.ive ways to modulate the energy band struc.ure and improve the photoc.talytic.ac.ivity of g-c.(3)N_(4). In this work, ultrathin defec.ive g-c.(3)N_(4) was suc.essfully prepared using c.ld plasma. Plasma exfoliation reduc.s the thic.ness of g-c.(3)N_(4) from 10 nm to 3 nm, while simultaneously introduc.ng a large number of nitrogen defec.s and oxygen atoms into g-c.(3)N_(4). The amount of doped O was regulated by varying the time and power of the plasma treatment. Due to N vac.nc.es, O atoms formed strong bonds with c.atoms, resulting in O doping in g-c.(3)N_(4). The mec.anism of plasma treatment involves oxygen etc.ing and gas expansion. Photoc.talytic.experiments demonstrated that appropriate amount of O doping improved the photoc.talytic.degradation of rhodamine B c.mpared with pure g-c.(3)N_(4). The introduc.ion of O optimized the energy band struc.ure and photoelec.ric.properties of g-c.(3)N_(4). Ac.ive spec.es trapping experiments revealed ·O_(2)^(–) as the main ac.ive spec.es during the degradation.
