Heterogenized magnetic graphene oxide‐supported N6‐Schiff base Cu (II) complex as an exclusive nanocatalyst for synthesis of new pyrido[2,3‐d]pyrimidine‐7‐carbonitrile derivatives

“…Nevertheless, these peaks at approximately 2θ = 12.8 o match with the oxygen functionalities even followed by magnetization and functionalization of graphene oxide. [ 88,89 ] The relative positions and intensities of all the peaks seen at 2θ = 35.69°, 30.3°, 53.5°, 43.47°, 62.89° and 57.3° correspond to the (311), (220), (422), (400), (440) and (511) reflection planes, respectively. The peaks are caused by the crystal planes in the Fe 3 O 4 lattice.…”

A Green Method to Prepare a Highly Concentrated Reduced Graphene Oxide (RGO) Dispersion and Its Anti‐Ultraviolet Radiation Property in RGO‐Modified Cotton Fabric

“…[10] During the past decades, strategies to produce graphene include: mechanical or ultrasonic exfoliation, [11] laser irradiation, [12] microbial reduction, [13] chemical vapor deposition (CVD), [14] solvothermal reduction, [15] and chemical reduction of dispersed graphene oxide (GO). [16] Of all the synthesis methods, the chemical reduction is deemed to be one the most economical approaches with potential production in full-scale. Nevertheless, it is noteworthy that many chemical reductants including hydrazine hydrate, [17] hydroiodic acid, [18] Zn powder, [19] and sodium borohydride [20] are extremely toxic or perilous, which are not suitable for application in biomaterials.…”

Electrochemical Sensing of Arsenic Ions Using a Covalently Functionalized Benzotriazole‐Reduced Graphene Oxide‐Modified Screen‐Printed Carbon Electrode

“…However, the majority of reducing agents, including hydrazine hydrate, sodium borohydride, and lithium aluminium hydride, are toxic and hazardous. [26][27][28][29] Therefore, research for alternative reducing agents is needed to combat chemical reducing agents. In recent years, various simple and eco-friendly green reductants such as green tea extract, [30] orange peel extract, [31] bougainvillea glabra flower extract, [32] tea polyphenol, [33] caffeic acid, [34] aloe vera extract, [35] and Hibiscus rosa-sinensis [8] have been used efficiently reduce GO.…”
