Abstract Over the last decade, exsolution has emerged as a powerful new method for decorating oxide supports with uniformly dispersed nanoparticles energy and catalytic applications. Due to their exceptional anchorage, resilience various degradation mechanisms, well numerous ways in which they can be produced, transformed applied, exsolved have set standards terms of activity, durability functionality. In conjunction multifunctional such perovskite oxides, becomes platform design advanced...
Renewable electricity‐driven electrochemical reduction of CO2 offers a promising route for production high‐value ethanol. However, the current state this technology is hindered by low selectivity and productivity, primarily due to limited understanding atomic‐level active sites involved in ethanol formation. Herein, we identify that interfacial oxygen vacancy‐neighboring Cu (Ov‐Cu) pair are electroreduction A linear correlation between density Ov‐Cu productivity experimentally evidenced....
Abstract Activating lattice oxygen linked to active sites at surface remains a fundamental challenge in many catalytic reactions. Here we create well‐defined by directly growing porous CeO 2 single crystals cm scale and confining Pt construct isolated 1 /CeO continuously twisted monolith. We demonstrate significantly enhanced activation of ions contrast Ce local structures. show complete CO oxidation with air 67 °C without degradation being observed after operation 300 hours.

Dry reforming of CH4 /CO2 provides an attractive route to convert greenhouse gas into syngas; however, the resistance sintering and coking catalyst remains a fundamental challenge at high operation temperatures. Here we create active durable metal-oxide interfaces in porous single-crystalline (PSC) CeO2 monoliths with situ exsolved (SC) Ni particles show efficient dry temperatures as low 450 °C. We excellent performance ≈20 % conversion ≈30 CO2 even continuous 240 hours. The well-defined...
Abstract A large amount of one‐dimensional (1D) Ce‐doped ZnO nanostructures with different morphologies has been successfully synthesized by annealing a polymeric precursor at various temperatures. The evolution the and microstructures was investigated field‐emission scanning electron microscopy (FE‐SEM), transmission (TEM), high‐resolution TEM (HRTEM). results show that vary drastically increasing synthesis temperature photoluminescence (PL) products depends on both measurement CeO layer...

The medium-sized Songjianghe Au deposit is located in the southeastern part of Jiapigou-Haigou gold belt (JHGB) central eastern Jilin Province, NE China. mineralization primarily characterized by disseminated-style ores and hosted low-/medium-grade metamorphic rocks Seluohe Group. ore bodies are governed NNW-striking brittle-ductile structures spatially correlated with silicic sericitic alterations. Four alteration/mineralization stages have been distinguished: (I) Quartz-pyrrhotite-pyrite,...

Continuous-wave (CW) room temperature operation of InGaN/GaN multi-quantum well (MQW) lasers is reported. Far-field beam divergence as narrow 13 degrees and 20 for parallel perpendicular directions to epilayer planes were measured, respectively. The MQW showed strong polarization anisotropy consistent with QW laser gain theory. Dependencies threshold current on cavity-length are also conventional No significant degradation in characteristics was observed during lifetime testing over 140...
