Abstract Producing electrolytes with high ionic conductivity has been a critical challenge in the progressive development of solid oxide fuel cells (SOFCs) for practical applications. The conventional methodology uses ion doping method to develop electrolyte materials, e.g., samarium-doped ceria (SDC) and yttrium-stabilized zirconia (YSZ), but challenges remain. In present work, we introduce logical design non-stoichiometric CeO 2-δ based on non-doped focus surface properties particles. 2−δ...
Nanosized, yet ordered: Active and selective Pd2Ga intermetallic compounds supported on carbon nanotubes have been synthesized applied to alkyne hydrogenation. Intermetallic the nanoscale are necessary achieve high mass activity, whereas ordered structures within form barriers for subsurface chemistry prevent large active ensembles Pd surface. Detailed facts of importance specialist readers published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset....
Sufficiently high oxygen ion conductivity of electrolyte is critical for good performance low-temperature solid oxide fuel cells (LT-SOFCs). Notably, material conductivity, reliability, and manufacturing cost are the major barriers hindering LT-SOFC commercialization. Generally, surface properties control physical chemical functionalities materials. Hereby, we report a Sm3+, Pr3+, Nd3+ triple-doped ceria, exhibiting highest ionic among reported doped-ceria oxides, 0.125 S cm-1 at 600 °C. It...

Although one of the most promising aqueous batteries, all Zn-Mn systems suffer from Zn dendrites and low-capacity Mn4+/Mn3+ process (readily leading to occurrence Jahn-Teller distortion, which in turn causes structural collapse voltage/capacity fading). Here, Mn3+ reconstruction disproportionation are exploited prepare stable, Mn2+-rich manganese oxides on carbon-cloth (CMOs) a discharged state through an inverted design, promotes reversible Mn2+/Mn4+ kinetics mitigates oxygen-related redox...
Hydrogen storage is a key link in hydrogen economy, where solid-state considered as the most promising approach because it can meet requirement of high density and safety. Thereinto, magnesium-based materials (MgH2) are currently deemed an attractive candidate due to potentially (7.6 wt%), however, stable thermodynamics slow kinetics limit practical application.
