Energy underlies the human development and welfare. Today energy depends on
combustion of fossil fuels (coal, natural gas, oil) sources. These sources have not only led to …

Two rare-earth zirconate oxides RE 2 Zr 2 O 7 (RE= La and Nd) with pyrochlore structures
were fabricated, employing a simple and modified solid-state route. After confirmation of …

Rare Earths (REs) are referred to as 'industrial vitamins' and play an indispensable role in a
variety of domains. This article reviews the applications of REs in traditional metallurgy …

Exploring non-noble metal and high-activity electrocatalysts through a simple and
controllable protocol remains a great challenge for oxygen reduction reaction (ORR) and …

随着社会的发展, 科学技术的不断提高, 人们发现稀土金属在提高产品质量,

The structural, morphological and optical properties of single-phase polycrystalline La 2− x
Sr x NiMnO 6 (x= 0, 0.3 and 0.5), synthesized by solid state reaction were investigated. The …

The stoichiometric LaCoO 3 and nonstoichiometric LaCo 1.2 O 3 perovskite catalysts were
prepared by citric acid sol–gel method, and then, LaCoO 3 perovskite was etched with nitric …

The current work examines the hydrogen storage properties of LaNiO3, a perovskite-type
oxide commonly used as a negative electrode in nickel-metal-hydride batteries. In the …

Alternative energy carrier materials are needed since non-renewable energy resources are
diminishing at a fast rate. Increasingly, hydrogen storage has gained popularity as a clean …

This work studied a hydrogen storage material which could absorbed hydrogen under room
temperature and 3 MPa hydrogen pressure. This material was obtained by hydrolysis of …
