标题 :Solvent-free synthesis of lanthanide oxide and mixed lanthanide oxide nanoparticles

摘要:Lanthanide oxides and mixed lanthanide oxides can be produced using furnace or microwave assisted solid-state synthesis. The use of Ln-tri(methylsilyl)amide-based precursors yields spherical nanoparticles. The formation of spherical shaped nanoparticles is likely due to the preferential single-step decomposition of the Ln-TMS as well as the low activation energy to overcome decomposition. Reaction temperature, initial metal ion ratio, and reaction dwell time can be used to control the final nanoparticle size. The method enables solvent-free, high-yield synthesis of morphology-controlled lanthanide oxides.

摘要:Disclosed are a catalyst for synthesis of methanol from synthesis gas and a method for preparing the same. The catalyst includes a Cu—Zn—Al oxide containing CuO, ZnO and Al 2 O 3 in a predetermined ratio or Cu—Zn—Al—Zr oxide containing CuO, ZnO, Al 2 O 3 and ZrO 2 in a predetermined ratio, in combination with a cerium-zirconium oxide obtained by a sol-gel process. As compared to the existing Cu—Zn—Al catalysts for synthesizing methanol, the catalyst disclosed herein inhibits formation of byproducts and improves yield of methanol. Therefore, it is possible to improve methanol purification efficiency and carbon conversion efficiency.

标 题 :Synthesis of high surface area, high entropy oxides

摘要:High surface area, high entropy oxides comprising multiple metal cations in a single-phase fluorite lattice material enables intrinsic catalytic activity without platinum group metals, tunable oxygen storage capacity, and thermal stability. These properties can be obtained through a facile sol-gel synthesis to provide a low-temperature route for production of phase-pure multi-cationic oxides. The resulting materials achieved significantly higher surface area and catalytic performance, taking advantage of all the properties endowed by the various cations in the composition.

权利人:NAT TECH & ENG SOLUTIONS SANDIA LLC; UNIV CALIFORNIA
摘要:Electrocatalytic reduction of waste nitrates (NO3−) enables the synthesis of ammonia (NH3) in a carbon neutral and decentralized manner. The present invention uses atomically dispersed transition metal-nitrogen-carbon (M-N—C) catalysts with varying metal centers to uniquely favor mono-nitrogen products (e.g., NH3) via the electrochemical nitrate reduction reaction (NO3RR).

摘要:The methanol electro-oxidation catalysts include nano-oxides of rare earth metals (i.e., cesium, praseodymium, neodymium and samarium) and platinum nano-particles. The nano-oxides of the rare earth metals are dispersed during synthesis of a support material, preferably formed from mesoporous carbon. The platinum nano-particles form between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, the rare earth metal forms between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, and carbon and oxygen forming the balance (between about 70 wt % and about 80 wt %) of the methanol electro-oxidation catalyst.
