THE CONTROLLED SYNTHESIS OF G-C3N4/CD-DOPED ZNO NANOCOMPOSITES AS POTENTIAL PHOTOCATALYSTS FOR THE DISINFECTION AND DEGRADATION OF ORGANIC POLLUTANTS UNDER VISIBLE LIGHT IRRADIATION

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 07 gennaio 2021 The in situ growth of well-dispersed Cd-doped ZnO nanoparticles (Cd-ZnO NPs) on graphitic carbon nitride (g-C3N4) nanosheets was successfully achieved through the co-precipitation method for the formation of Cd-doped ZnO nanocomposites with g-C3N4 (Cd-ZnO/g-C3N4 NCs). The effect of different compositions of......

NEW INSIGHTS INTO THE BIPHASIC “CO-FREE” PAUSON-KHAND CYCLISATION REACTION THROUGH COMBINED IN SITU SPECTROSCOPY AND MULTIPLE LINEAR REGRESSION MODELLING

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 06 gennaio 2021 “CO-free” carbonylations are catalytic reactions, which strive to replace toxic synthesis gas for less harmful surrogate molecules like formaldehyde. This study sheds light on the mechanism of the biphasic, Rh-catalysed Pauson-Khand type cyclisation reaction by applying in situ Raman spectroscopy together......

INFLUENCE OF HIDDEN HALOGEN MOBILITY ON LOCAL STRUCTURE OF CSSN(CL1-XBRX)3 MIXED-HALIDE PEROVSKITES BY SOLID-STATE NMR

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 30 dicembre 2020 Tin halide perovskites are promising candidates for lead-free photovoltaic and optoelectronic materials, but not all of them have been well characterized. It is essential to determine how the bulk photophysical properties are correlated with their structures at both short and long......

HETEROBIMETALLIC RARE EARTH METAL-ZINC CATALYSTS FOR REACTIONS OF EPOXIDES AND CO2 UNDER AMBIENT CONDITIONS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 18 dicembre 2020 Four homodinuclear rare earth metal (RE) complexes 1-4 bearing a multidentate diglycolamine-bridged bis(phenolate) ligand were synthesized. In addition, seven heterobimetallic RE-Zn complexes 5-11 were prepared through a one-pot strategy. In these heterobimetallic complexes, two RE centers are bridged by either Zn(OAc)2......

THE EFFECT OF NANOPARTICULATE PDO CO-CATALYSTS ON THE FARADAIC AND LIGHT CONVERSION EFFICIENCY OF WO3 PHOTOANODES FOR WATER OXIDATION

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 14 dicembre 2020 WO3 photoanodes offer rare stability in acidic media, but are limited by their selectivity for oxygen evolution over parasitic side reactions, when employed in photoelectrochemical (PEC) water splitting. Herein, this is remedied via the modification of nanostructured WO3 photoanodes with surface......

TRANSFORMING GLYCEROL AND CO2 INTO GLYCEROL CARBONATE OVER LA2O2CO3–ZNO CATALYST — A CASE STUDY OF THE PHOTO-THERMAL SYNERGISM

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 10 dicembre 2020 The direct synthesis of glycerol carbonate via glycerol carbonylation by CO2 suffers from thermodynamic limitation. In this study, light was introduced into the thermal-driven reaction system to synergistically break the equilibrium of the reaction. A series of xLa2O2CO3–ZnO catalysts were prepared......
