Preparation of a Photosensitive Composite Carbon Fiber for Spilled Oil Cleaning

Abstract

This paper deals with preparing a functional composite carbon fiber with a large surface area for spilled oil cleaning. The composite fiber consisted of photosensitive oxide particles and polymer-derived carbon. It was made by co-spinning the polymer and metallic compounds. After heat treatment at high temperatures, an activated carbon fiber containing oxide particles was obtained. The particles were found distributed in the fiber and at the surface of the fiber. The composite fiber was found sensitive to sunlight. Fiber mats made of the composite fiber possessed a high surface area for oil absorption and removal. Cobalt(II) titanate particles were obtained from the reaction of titanium dioxide and cobalt oxide. The reaction happened in situ through the hydrolysis of metallic compounds in the spun fiber. The titanium dioxide and cobalt(II) titanate particle-containing fibers demonstrated the photoactivity in the visible light spectrum. It was concluded that particle-containing composite carbon fiber mats can be prepared successfully by co-electrospinning. Due to the oleophilic property and the high active surface area, the composites are suitable for spilled oil cleaning through fast absorption.

Seawater Corrosion of Copper and Its Alloy Coated with Hydrothermal Carbon

“…A pressure gauge with the resolution of 0.1 MPa was connected to the reaction chamber by a stainless-steel tube to monitor the pressure level during the whole period of hydrothermal carbonization. Pictures showing the surface of both coated and uncoated specimens were taken using a Cannon T6 camera as also used for capturing images of fiber mats [21]. The seawater corrosion property of the hydrothermal carbonization coated specimens was tested using the CHI6005E at room temperature.…”

Optimisation Methodology for Skimmer Device Selection for Removal of the Marine Oil Pollution

“…It can be time-consuming and expensive when it is used on a large scale, and it requires a large number of staff and equipment. Moreover, cleaning costs rapidly increase with each additional cleaning hour [20,21].…”
