摘要： Carbon nanofiber doped alumina (Al-CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al-CNF-supported MoCo catalysts, (Al-CNF-MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al-CNF-MoCo has a higher catalytic activity than Al—MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al—MoCo may be 75% less than Al-CNF-MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.

摘要： A composite of polyurethane foam grafted with carbon nanofibers is described. This composite foam may be made by contacting and drying a polyurethane foam with a suspension of carbon nanofibers and then drying. Additional carbon nanofiber layers may be added with repeated contacting. The composite film has a high surface area of 276 m2/g and a hydrophobic character that may be exploited for separating an oil phase from water.

摘要： A crosslinked polymer that is in the form of a Mannich polycondensation product including reacted units of a cyclic diaminoalkane, an aldehyde, and bisphenol-S or melamine. Also disclosed is a method for removing heavy metals from an aqueous solution by contacting the aqueous solution having an initial concentration of the heavy metal with the crosslinked polymer to form a mixture, and filtering the mixture to obtain an aqueous solution having a reduced concentration of the heavy metal compared to the initial concentration.

摘要： A rotating sample platform for SERS detection having sample holders for presenting a plurality of samples to a SERS laser at a speed and dwell time related to the Raman spectra. The sample holder may be designed to hold either slides or cuvettes, each of which contains either gold or silver nanoparticles. The sample holder for slides is configured for tilting each slide. The degree of tilt is captured by a wireless read head. A controller is configured to receive the wireless read head signals and the Raman spectra for each sample, correct the speed and dwell time and actuate a motor to rotate the sample platform at the corrected speed and dwell time. The rotating sample platform allows a set of slides or cuvettes in a sample holder to be presented to the SERS detector in a continuous manner, minimizing background corrections and sample adjustment time.

摘要： Vapor phase polymerization can be used to synthesize a 3D porous network of polystyrene-containing, branched carbon nanofibers on polyurethane(s), optionally using natural light (NL) initiation. NL styrene polymerization in a confined reactor containing CNF-grafted PU can provide a stable porous network. The NL can vaporize the styrene by increasing the reactor temperature and generate styrene radicals. Without CNF, the polymerization on polyurethane (PU) provides a delicate, fragile surface. Radical styrene in vapor phase can interact with CNF to produce polystyrene branches by generating active sites on CNF, while reinforcing the 3D porous structure. After polymerization, the PU surface area increased from 9 to 184 m2/g and pore size decreased from 2567 to 10 Å. 3D porous networks of NL-assisted PS branched CNF supported PU can provide a hydrophobic, oleophilic surface with a water contact angle of approx 148±3°, rapidly gravity separating hexane and water without external force.
