Mn and Na additives have been widely studied to improve the efficiency of CO2 hydrogenation valuable olefins on Fe catalysts, but their effects catalytic properties mechanism are still under vigorous debate. This study shows that Fe-based catalysts with moderate contents highly selective for olefins, together low selectivities both CO CH4 much improved space-time olefin yields compared state-of-the-art catalysts. Combined kinetic assessment quasi in situ characterizations further unveil sole...
Conversion of CO2 into fuels via solar energy would be a promising strategy to reduce emissions and produce value-added carbon compounds. However, the development efficient light-harvesting photocatalytic systems remains significant challenge because scarcity low-cost high-efficiency catalysts in conversion. Herein, tunable selectivity photothermal conversion was demonstrated over series Fe-based developed through simple hydrogenation/carbonization treatment with commercial Fe3O4 as...
In comparison to the traditional petroleum-based plastics, polylactic acid, most popular biodegradable plastic, can be decomposed into carbon dioxide and water in environment. However, natural degradation of acid requires a substantial period time and, more importantly, it is carbon-emitting process. Therefore, highly desirable develop novel transformation process that upcycle plastic trash value-added products, especially with high chemical selectivity. Here we demonstrate one-pot catalytic...
Transition metal metaphosphates and noble phosphides prepared under similar conditions are potential hybrid catalysts for electrocatalytic water splitting, which is of great significance H2 production. Herein, the structure activity different species (i.e., Rh, Pd, Ir) on CoNiP4O12 nanoarrays have been systematically studied. Due to formation energies phosphides, Rh (RhPx) Pd (PdPx) as well Ir obtained same phosphorylation perspectively. RhPx/CoNiP4O12 PdPx/CoNiP4O12 exhibit much better HER...
Titanate nanofibers with two formulas, Na2Ti3O7 and Na1.5H0.5Ti3O7, respectively, exhibit ideal properties for removal of radioactive heavy metal ions in wastewater, such as Sr2+, Ba2+ (as substitute 226Ra2+), Pb2+ ions. These can be fabricated readily by a reaction between titania caustic soda have structures which TiO6 octahedra join each other to form layers negative charges; the sodium cations exist within interlayer regions are exchangeable. They selectively adsorb bivalent from water...
Abstract Despite significant advances in iron oxide nanoparticles, it is still a challenge to synthesize regular polyhedral single‐crystalline α‐Fe 2 O 3 particles because the surface energies of several low‐index planes are fairly similar. In work presented here, well‐dispersed and dodecahedral octodecahedral synthesized by facile hydrothermal method with aid F − anions. The crystalline structure disclosed various characterization techniques. hexagonal bipyramidal shape enclosed twelve...

Abstract Long-chain alcohols synthesis (LAS, C 5+ OH) from syngas provides a promising route for the conversion of coal/biomass/natural gas into high-value chemicals. Cu-Fe binary catalysts, with merits cost effectiveness and high CO conversion, have attracted considerable attention. Here we report nano-construct Fe 5 2 -Cu interfacial catalyst derived Cu 4 1 Mg -layered double hydroxide (Cu -LDH) precursor, i.e ., clusters (~2 nm) are immobilized onto surface nanoparticles (~25 nm). The...
Daytime radiative coolers cool objects below the air temperature without any electricity input, while most of them are limited by a silvery or whitish appearance. Colored daytime (CDRCs) with diverse colors, scalable manufacture, and subambient cooling have not been achieved. We introduce polymer–Tamm photonic structure to enable high infrared emittance an engineered absorbed solar irradiance, governed quality factor (Q-factor). theoretically determine theoretical thresholds for through...
