The hydrogenation of 4-nitrophenol (4-NP) has attracted much attention, since it is typically used as a model reaction for evaluating newly developed catalysts, but its mechanism still debated. Herein, Co(OH)2-modified CuO catalyst (Co(OH)2/CuO) was the reduction 4-NP to 4-aminophenol (4-AP) in an aqueous sodium borohydride (NaBH4) solution. investigated by UV-Vis spectroscopy (UV-Vis), high-pe...

In this study, glutaraldehyde cross-linked chitosan support, as well the catalysts obtained after loading Ag metal (Ag/Chitosan), were synthesised and applied for adsorption reduction of phenol red dye in an aqueous solution. The Ag/chitosan characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) inductively coupled plasma-op...

Bu çalışmada Co0,92-xMn0,08Ptx/TiO2 ve Co0,92-xMn0,08Ptx/Al2O3 nano katalizörleri sentezlenmiştir. Destekli katalizörlerin üretilmesinde impregnasyon tekniği kullanılmıştır. Katalizörlerin hidroliz yöntemi ile NaBH4’ü parçalararak yüksek hızda hidrojen üretme yetenekleri belirlenmiştir. özelliklerinin belirlenmesi için geçirimli taramalı electron mikroskopları (TEM SEM), X-ışını difraktometresi...

The synthesis of palladium-based trimetallic catalysts via a facile and scalable procedure was shown to yield highly promising materials for borohydride-based fuel cells, which are attractive use in compact environments. This, thereby, provides route more environmentally friendly energy storage generation systems. Carbon-supported were herein prepared by three different routes: using NaBH4-ethy...

Nickel nanoparticles (Ni NPs) supported on Poly(vinylidene fluoride-co-hexafluoropropylene) nanofibers (PVDF-HFP NFs) were successfully synthesized through electrospinning and in-situ reduction of Ni2+ salts into the surface PVDF-HFP NFs to form metallic Ni [email protected] NFs. Different percentages nickel acetate tetrahydrate (NiAc) (10 %, 20 30 40 % wt.) based PVDF-HFP. The formation tiny N...
