The doping of In2O3 significantly promoted the catalytic performance Co3O4 for CO oxidation. activities In2O3–Co3O4 increased with an increase in content, form a volcano curve. Twenty-five wt % (25 InCo) showed highest oxidation activity, which could completely convert to CO2 at temperature as low −105 °C, whereas it was only −40 °C over pure Co3O4. induced expansion unit cell and structural distortion Co3O4, confirmed by slight elongation Co–O bond obtained from EXAFS data. red shift UV–vis...

Electrocatalytic NO reduction reaction (NORR) offers a promising route for sustainable NH3 synthesis along with removal of pollutant. However, it remains great challenge to accomplish both high production rate and long duration satisfy industrial application demands. Here, we report an in situ-formed hierarchical porous Cu nanowire array monolithic electrode ensembled pressurized electrolyzer regulate NORR kinetics thermodynamics, which delivers industrial-level partial current density 1007...
Free-standing, hierarchical, ultrathin, and two-dimensional (2D) polycrystalline Co3O4 flowers were synthesized by a hydrothermal topotactic transformation process. Aberration-corrected electron microscopy study of both the CoOx precursor structure subsequent processes revealed nucleation growth mechanisms 2D nanosheets. The free-standing flower-shaped powders (1–5 μm) consist numerous self-assembled nanocrystallites (average size ∼1.8 nm). After transformation, via rapid calcination...
Identifying the activity origin of noble-metal-based catalysts is extremely important for fundamental research and practical application. We report that single Au atoms on Co3O4 (Au1/Co3O4 single-atom (SAC)) exhibit excellent stability CO oxidation Au1/Co3O4 SAC an active area centered by Au1 atom with one nearby Co O (and/or vacancy). The turnover frequency 3.1 s–1 at −75 °C, to our knowledge, which makes most oxidation. can be maintained after 10 cycles temperature-programmed reaction from...
Three Pd/CeO<sub>2</sub> catalysts are synthesized by reduction-deposition and an impregnation method (IMP) to clarify how the chemical state of Pd influences catalytic performance for CH<sub>4</sub> combustion.
CO adsorption and O<sub>2</sub> activation played important roles in oxidation on a supported Pd catalyst, which was dependent the chemical state of Pd.
Piezotronic transistors (PTs) that utilize inner crystal potential generated by interface piezoelectric polarization charges as the gate voltage have great applications in force/pressure-triggered or controlled electronic devices, sensors, human–machine communication, and microelectromechanical systems. Although performance of PTs has been partially enhanced exploring special materials with different geometries high piezoelectricity, few studies focused on structure design PT itself to more...
Catalytic oxidation is believed to be the most efficient method for indoor formaldehyde purification. Herein, we reported that Pt/Na-ZSM-5 catalyst with low Pt loading (0.16 wt %) prepared by depositing on Na+ ion-exchanged ZSM-5 could completely oxidize 300 ppm in 2.5 vol % H2O at 32 °C and maintain its activity during 62 h-long stability test. Multiple characterizations revealed presence of Na species significantly enhanced adsorption ability made tend exist form metal through electron...
We report the effect of in situ transforming ZnO supported single Au atoms to 3-dimensional clusters (Au3D) on room temperature CO oxidation activity. discovered that an intermediate, highly distorted 2-dimensional layer species is much more active than both Au3D and atoms. The geometric arrangement their interactions with support surfaces play a pivotal role determining catalytic performance catalysts.
Abstract Enabling high‐efficiency solar thermal conversion (STC) at catalytic active site is critical but challenging for harnessing energy to boost reactions. Herein, we report the direct integration of full‐spectrum STC and high electrocatalytic oxygen evolution activity by fabricating a hierarchical nanocage architecture composed graphene‐encapsulated CoNi nanoparticle. This catalyst exhibits near‐complete 98 % absorptivity spectrum efficiency 97 %, which superior than previous materials....
