In the current world situation, population and industrial growth have become major problems for energy environmental concerns. Extremely noxious pollutants such as heavy metal ions, dyes, antibiotics, phenols, pesticides in water are main causes behind deprived quality leading to inadequate access clean water. this connection, graphite carbon nitride (GCN or g-C3N4) a nonmetallic polymeric material has been utilized extensively visible-light-responsive photocatalyst variety of applications. This review focuses on recent developments design photocatalytic applications metal-doped GCN-based nanomaterials CO2 photoreduction, splitting toward hydrogen production, bacterial disinfection, organic pollutant degradation. Additionally, discusses various methods using materials optimize dye sensitization, deposition, ion doping, their

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) has received a significant importance in organic synthesis during recent years because of its interesting ability to catalyze reaction sufficiently at mild conditions. DBU can work as catalyst under simple conditions inducing the operational simplicity experimental procedures by reducing side products and waste. The notable advantages these cases include less expensive which is commercially readily available, easy handle, most importantly recoverable. been explored for several practical methodologies highly useful wide variety materials. selectivity (chemo-, regio-, stereo-) reactions impressive applicable modern chemical transformations. possesses enhanced basic properties high mechanical well thermal stability. In years, large number transformations have carried out using catalyst. successfully employed conduct including usual modifications, cyclizations, eliminations, esterifications, condensation reactions, multicomponent etc. fact, last few decades, tremendous interest sparked various promoted publications appeared literature. Since catalyzed recently proven be important we review this article protocols

Fabrication of noble metal nanoparticles by using green chemical method with plant extract as reducing agent to the in situ oxidation toxic water contaminants have been subject various investigators due their enhanced catalytic efficiencies. This paper describes extraction caffeic acid from Artemisia herba-alba aqueous extract, and preparation silver (Ag), platinum (Pt), silver-platinum (Ag-Pt) a capping agent. The as-prepared Ag-Pt NPs was used heterogeneous activator persulphate (K2S2O8) for malachite (MG). shows no surface Plasmon resonance absorption band. dye completely decolorized presence Ag-Pt/K2S2O8 system. SO4-• HO• radicals generated cleavage S2O82- peroxide activation were responsible MG decolorization well mineralization. acted sacrificial electron donor. characterized conventional techniques such as, UV–visible, FTIR, SEM, TEM, EDX, XPS, XRD spectroscopic methods.

The Pipper nigram (P. nigram) leaf extract was used for the biosynthesis of copper oxide nanoparticles (CuO NPs) and successful formation resultant product confirmed through several physicochemical techniques. chemical structure elemental composition were analysed Fourier transform infrared (FTIR) energy dispersive X-ray (EDX) spectroscopies, respectively. crystalline crystallite size investigated an diffractometer (XRD) a monoclinic with 40.68 nm reported. Even-distributed particles average particle 49.75 seen in scanning electron micrograph (SEM), whereas thermal stability checked during thermogravimetric analysis (TGA). ultra-violet visible (UV-Visible) spectroscopy operated to study light absorbance phenomena determine band gap from absorption edge, which found be 1.47 eV. CuO NPs as antibacterial agents against gram-negative bacteria (GNB) gram-positive (GPB), greater inhibition zones former one. antioxidant test also carried out 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals potential higher than ascorbic acid.
