Herein we report a Cu<sub>2</sub>O–TiO<sub>2</sub>/rGO photocatalyst with phenomenal water splitting ability.
Combinations of different Advanced Oxidation Processes (AOPs) are being exploited for waste water treatment. The usage ultrasound in photocatalysis finds much attention as the combined process offers some advantages over individual processes. Herein, we report assisted photocatalytic degradation an organic pollutant (methyl orange a model dye) presence CuO-TiO2/rGO photocatalyst which was prepared by simple wet impregnation method. A synergistic effect (3.7-fold) observed combining sonolysis...
The present work demonstrates a new simple hand-picking technique for the 100% recovery of CuO nanosphere photocatalyst.
In this study, ruthenium nanoparticles (RuNPs) were successfully decorated on graphene nanosheets (GNSs) for the very first time by a dry synthesis method. The resultant material (GNS-RuNPs) was used as nanocatalyst aerial oxidation of alcohols after being optimized. scope catalytic system extended with various aliphatic, aromatic, alicyclic, benzylic, allylic, amino, and heterocyclic alcohols. 0.036 mol % (5 mg) catalyst enough alcohols, lowest amount so far reported. proposed is highly...
Abstract A new class of pyridyl benzimdazole based Ru complex decorated polyaniline assembly (PANI-Ru) was covalently grafted onto reduced graphene oxide sheets (rGO) via covalent functionalization approach. The attachment PANI-Ru with rGO confirmed from XPS analysis and Raman spectroscopy. chemical bonding between induced the electron transfer to backbone conjugated PANI chain. resultant hybrid metallopolymer successfully demonstrated as an donor in bulk heterojunction polymer solar cells...
Herein, Cu2O spheres were prepared and encapsulated with reduced graphene oxide (rGO). The Cu2O–rGO–C3N4 composite covered the whole solar spectrum significant absorption intensity. rGO wrapped loading caused a red shift in respect to considering of bare C3N4. photoluminescence study confirms that exploited as an electron transport layer at interface C3N4 heterojunction. Utmost, ∼2 fold synergistic effect was achieved for photocatalytic reduction 4-nitrophenol 4-aminophenol comparison...
Copper(II) oxide (CuO) nanoparticles have been synthesized from copper acetate by simple precipitation method and were found to be an efficient inexpensive catalyst for C–N cross-coupling reactions of benzimidazole with various aryl halides.

Benzimidazole undergoes reaction bromides, chlorides, or fluorides in the presence K2CO3 at moderate temperature. yield...
A CuO nanoparticles (CuO NPs)/graphene nanosheet (GNS) hybrid was prepared by a very simple method and employed as nanocatalyst (CuO/GNS) for base free coupling reactions, namely, A3-coupling aza-Michael reactions. TEM shows that NPs of below ∼35 nm size are homogeneously dispersed on the GNS. Strong adhesion between GNS acknowledged high Raman ID/IG ratio XPS result. The BET surface area CuO/GNS found to be 66.26 m2 g–1. EDS investigations revealed weight percentage chemical state Cu in...
