In this study, single wall carbon nanotubes (CNTs)/reduced graphene oxides (rGO) aerogels were prepared by a one-pot hydrothermal process without using a binder.

ABSTRACT:Oil palm empty fruit bunch (EFB), a natural polymeric material from the palm oil tree, is a potential precursor for making carbon for advanced materials applications because of its continuous generation in large quantities as a low cost by-product of the palm oil mill; annual production of EFB in Malaysia is approximately 2 million tonnes. Powders of natural pyropolymer having self-adhesion property, NPP1, NPP2, and NPP3, were prepared by precarbonizing the EFB, EFB treated with acid (1% HCL), and alkaline (1% NaOH) respectively. Green bodies of carbon pellets prepared from the NPP1, NPP2, and NPP3 were carbonized up to 1000• C using a multistep heating profile. Hardness of the Correspondence to: M. Deraman;

In this paper, the development of regenerated cotton linter cellulose membranes embedded with ZnO nanoparticles was conducted using the dissolution-regeneration process. The physical and chemical properties of composite membranes were characterized using X-ray diffraction, field-emission scanning electron microscopy, Fourier-transform infrared spectroscopy, ultraviolet-visible spectroscopy, and thermogravimetric analysis. The characterizations revealed that the addition of ZnO nanoparticles changes the crystallinity, bond properties, thermal properties, and hydrophilicity of the regenerated cellulose membrane. These nanocomposite membranes demonstrated good capability in water absorption, with pore volumes ranging from 3.6 to 2.1 cm 3 /g. In the photocatalytic studies, the cellulose membranes incorporating ZnO particles (1.6 wt%) can remove up to 87.6% of MB in 100 min under UV irradiation and also maintained reusability (84%) after sixth cycles after 6 months.Taken together, this bifunctional cellulose/ZnO membrane is a promising material for solving the wastewater crisis.
