Boron nitride is a unique material that has attracted a lot of scientific interest over the years. A variety of researchers find boron-nitride an excellent material.

Rice University researchers believe that graphene separated from boron nanotube columns could make a good material to store hydrogen fuel in an automobile.

The Department of Energy set the bar for storage materials and made hydrogen practical for use in light-duty vehicles. Rouzbeh Shahsavari of Rice Lab, materials scientist, determined in a recent computational study that pillared graphene or boron Nitride might be an option.

Shahsavari has used computer modeling to determine the elastic and elastic columnar graphene shapes. Later, Shahsavari processed the boron nutride nanotubes into a mixture in order to create a unique 3-D structure. This is a sample of boron-nitride Nanotubes that have been seamlessly bonded with graphene.

As the pillars allow for space between floors in a building, so too do the pillars inside the boron nutride graphene. Their challenge is getting them in, keeping enough, and then getting out as often as possible.

Researchers found that graphene pillared or pillared with boron nuitride graphene has an extremely rich surface area of 2,547 square metres per square meter and excellent recyclability in ambient conditions. They found that adding oxygen and lithium to the materials will improve their ability to be combined with hydrogen.

Simulators focused on simulations of four variations: one pillared structure for boron nutride, or one pillared graphene for boron nanotride doped with lithium or oxygen.

At room temperature and ambient pressure oxygen-dopedboron nuitride graphene performed the best. The material weighed in at 11.6% and approximately 60 g/L, respectively. This makes it an easy opponent to porous and metal oxide skeletons, carbon nanotubes, and other competing technologies.

At -321 degrees Fahrenheit the material’s hydrogen weight was 14.77%.

US Department of Energy currently targets economic storage media to contain more than 5.5% of weight and 40g per liter of hydrocarbon under mild conditions. Maximum goal 7.5% in weight and 70 grams per Liter.

Shahsavari explained that the weak van der Waals force causes hydrogen atoms to be attracted on undoped, pillared Boron Nitride graphene. Doping the material with oxygen makes the atoms bind strongly to the mixture, creating a better surface for the incoming hydrogen. Shahsavari suggests that the hydrogen may be transported under pressure, and then withdrawn when pressure is released.

“Because we know the nature and interactions of charges, adding oxygen to the substrate makes us a good bond,” said he. The chemical affinity between hydrogen and oxygen is known.”

Shahsavari explained that graphene’s polarization properties combined with the graphene’s electron mobility make it extremely tunable for applications.

Shahsavari states that “what we’re looking for” is the optimal point. This refers to the equilibrium between the surface area and the weight of the material as well as the operating temperature and pressure. Because we are able to test many variations quickly, computational modeling is the only way to do this. For the researcher to be able to do the job in a matter of days, it takes several months.

According to him, these structures need to be strong enough that they can easily surpass the Department of Energy’s requirements. For example, the hydrogen fuel tanks must withstand 1500 charges and discharge cycles.
