comparison of nonprecious metal cathode materials for methane

The highest power densities for Fe-N-C and Co-N-C are reported to be 1.18 and 0.87 Wcm-2 with O 2 at the cathode, respectively. Despite the significant progress in non-precious metal catalysts development, the undesired durability (only a few hundreds of hours) is still far from the target of 5000 h by 2025.

Metal

2017/12/1The inorganic materials could be metals, metal oxides, or metal carbides, depending on the type of metal and synthetic conditions (82–85). Because of the homogeneous and localized reactions between metal nodes and organic linkers in the nanometer scale, the derived materials normally exist as composites of metal-containing nanoparticles or even atoms/clusters and carbonaceous components

Stanford scientists use microbes to make 'clean'

At Penn State, Logan's lab is designing and testing advanced cathode technologies that will encourage the growth of methanogens and maximize methane production. The Penn State team is also studying new materials for electrodes, including a carbon-mesh fabric that could eliminate the need for platinum and other precious metal catalysts.

2021/5/4Fluctuations in the fuel flow rate may occur in practical combustion systems and result in flame destabilization. This is particularly problematic in lean and ultralean modes of burner operation. In this study, the response of a ceramic porous burner to fluctuations in the flow rate of different blends of methane and hydrogen is investigated experimentally. Prior to injection into the porous

2020/11/26The development of active and low-cost electrocatalysts for the oxygen reduction reaction (ORR) is crucial for the sustainable commercialization of fuel cell technologies. In this study, we have synthetized Me/Mo2C (Me = Fe, Co, Cu)-based composites embedded in N- and P-dual doped carbon by means of inexpensive industrial materials, such as melamine and chitosan, as C and N sources, and

Highly active dry methane reforming catalysts with

With the need for more stable and active metal catalysts for dry reforming of methane, in situ grown nanoparticles using exsolution are a promising approach. However, in conventional exsolution, most nanoparticles remain underneath the surface because of the sluggish diffusion rate of cations. Here, we report the atomic layer deposition (ALD)–combined topotactic exsolution on La0.6Sr0.2Ti0
