Synthesis of Nanocrystalline Iron Nitrides Using Two-Step Reactive Milling Process

Nanocrystalline iron nitride is an important soft magnetic material; however, conventional methods of production don’t exist. Synthesis of dense nanocrystalline iron nitrides is not possible by simply annealing elemental iron in NH3 at temperatures in excess of 600° C since g’-Fe4N and other iron nitrides are unstable above 600°C and will decompose. Sandia researchers have discovered that by using a two-step reactive milling process and high pressure spark plasma sintering (SPS) they can quickly and efficiently fabricate bulk g’-Fe4N parts.

New Non-Platinum Fuel Cell Catalyst

The Kisailus research group at the University of California, Riverside, has  developed a novel fuel cell catalyst made of porous carbon nanofibers doped with inexpensive metal or metal oxide nanoparticles that provide active sites for energy conversion and storage. The active or catalytic nanoparticles are embedded and integrated with graphitic nanofibers and are accessible to the surrounding environment due to high porosity. The extensive graphitic networks within these nanofibers also exhibits enhanced conductivity. Cobalt oxide- graphite composite nanofibers showed equivalent catalytic activity to fuel cell platinum catalysts like platinum on carbon (Pt/C). When operated under fuel cell conditions, the nanofiber formulation provides enhanced durability.  Fig. 1 Metal oxide-graphite composite and porous nanofibers with highly controllable diameter, particle size and performance. Fig. 2 Linear sweep voltametry curves shows that the graphitic nanofibers doped with metal ions have higher current densities than commercial platinum on carbon (Pt/C).

Selective Nitrogen Adsorption Using a Vanadium Metal-Organic Framework

Natural gas, composed primarily of methane, has many potential uses as a cleaner and more renewable source of energy than other fossil fuels. However, about 20% of US natural gas reserves contain levels of N2 that are too high for pipeline processing. Using natural gas from renewable sources also encounters this problem. Furthermore, in processing steps to create high-purity methane from its various sources, the removal of N2 remains a significant energetic cost. This separation is typically performed through cryogenic distillation, and improvements in energy efficiency of this separation are necessary to utilize the many available sources of methane. Switching to membrane or adsorbent-based technologies could potentially alleviate this challenge. Size selective molecular sieves and membranes have demonstrated some ability for separating N2 from CH4, but face problems with scalability and selectivity; and current adsorbents need significant improvements in selectivity and capacity for N2 to be commercially viable.  To address this situation, researchers at UC Berkeley have developed a new adsorbent V2Cl2(btdd) with exceptional affinity for nitrogen, such that early experiments already demonstrate a N2/CH4 selectivity of over 10x greater than any reported material. The Berkeley material is a permanently porous vanadium(II)-containing metal-organic framework (MOF). It represents the first example of a MOF with five-coordinate vanadium(II) centers as the primary metal node. The electronic properties of these five-coordinate V(II) centers make this MOF uniquely reactive towards relatively inert and weak electron acceptors, such as nitrogen, creating a stronger M–N2 interaction than any known MOF. Additionally, the high-density of V(II) centers translates to a high gas uptake capacity, qualifying this material as a promising N2/CH4 selective adsorbant. Key performance parameters can be tuned as the building blocks are synthetically modifiable.
