Carbon dioxide (CO2) hydrogenation to methanol with H2 produced renewable energy represents a promising path for the effective utilization of major anthropogenic greenhouse gas, in which catalysts play key role CO2 conversion and selectivity. Although still under development, indium oxide (In2O3)-based have attracted great attention recent years due excellent selectivity along high activity conversion. In this review, we discuss advances In2O3-based based on both experimental computational...
Effective HER activity on layered double hydroxide nanosheets through a plasma etching strategy.
Bimetallic NiFe catalysts have emerged as a promising alternative to the traditional Ni for CO2 methanation. However, promoting effect of Fe on bimetallic remains ambiguous. In this study, series derived from hydrotalcite precursors were investigated. situ x-ray diffraction (XRD) analysis revealed that small alloy particles formed and remained stable during reaction. When Fe/Ni = 0.25, exhibited highest conversion, CH4 selectivity stability in methanation at low temperature 250–350 °C. The...
Identifying the dynamic structure of heterogeneous catalysts is crucial for rational design new ones. In this contribution, structural evolution Fe(0) during CO2 hydrogenation to hydrocarbons has been investigated by using several (quasi) in situ techniques. Upon initial reduction, Fe species are carburized Fe3C and then Fe5C2. The by-product hydrogenation, H2O, oxidizes iron carbide Fe3O4. formation Fe3O4@(Fe5C2+Fe3O4) core-shell was observed at steady state, surface composition depends on...
Cobalt catalysts supported on TiO2 with different crystal forms (anatase and rutile) differ sharply in CO2 conversion product selectivity for hydrogenation. The Co/rutile-TiO2 catalyst selectively catalyzed hydrogenation to CH4, while CO is the main Co/anatase-TiO2 catalyst. In situ DRIFT (diffuse reflectance infrared Fourier transform) results have partially revealed reaction pathway of these two catalysts. On Co/rutile-TiO2, proceeds through key intermediate formate species, which further...
Particle size is an important parameter of supported catalysts, but understanding the size-performance relationship a challenge, especially in some complicated process. In this contribution, particle effect on CO2 hydrogenation to hydrocarbons over iron-based catalysts was deconvoluted into effects primary and secondary reactions. With range 2.5–12.9 nm, overall selectivity C2+ increases continuously, while that CO decreases with increasing size. The reverse water gas shift (RWGS) reaction...
Understanding the structure–catalytic activity relationship is crucial for developing new catalysts with desired performance. In this contribution, we report performance of In2O3 different crystal phases in reverse water gas shift (RWGS) reaction, where observe changing induced by a phase transition under reaction conditions. Cubic (c-In2O3) exhibits higher RWGS rate than hexagonal (h-In2O3) at temperatures below 350 °C because its (1) enhanced dissociative adsorption H2, (2) facile...
Se-doped MnS/NiS as a highly efficient bifunctional electrocatalyst.
Surface suppression is one of critical issues for semiconductors in photoelectrochemical (PEC) water splitting. Deposition oxygen evolution cocatalysts on photoanodes can improve the rate, but still it has some limits cases. In this work, we propose a new and simple precipitation approach to transform surface hematite into iron phosphate (Fe–Pi). Further, Ar-plasma treatment Fe–Pi/Fe2O3 introduces vacancies phosphorous photoanode. A accelerates transfer holes from bulk surface. Besides,...
Fine tuning the structure of bimetallic nanoparticles is critical toward understanding structure–activity relationships and further improving catalytic performance in propane dehydrogenation (PDH). Excessive Fe species PtFe catalysts promote carbon deposition leading to low propylene selectivity, it remains challenging synthesize well-defined while selectively eliminating excessive Fe. Herein, we show that formation coke can be significantly inhibited by introducing CO2 into PDH over...
The decomposition of cobalt carbide (Co 2 C) to metallic in CO hydrogenation results a notable drop the selectivity valued C 2+ products, and stabilization Co remains grand challenge. Here, we report an situ synthesized K-Co catalyst, hydrocarbons achieves 67.3% at 300°C, 3.0 MPa. Experimental theoretical elucidate that CoO transforms reaction, while is dependent on reaction atmosphere K promoter. During carburization, promoter H O jointly assist formation surface * species via carboxylate...
In hybrid organic-inorganic perovskite solar cells (PSCs), interfacial engineering can efficiently improve the photovoltaic performance. this work, planar π-conjugated porphyrin, zinc(II) 5,10,15,20-tetrakis[5-(p-acetylthiopentyloxy)phenyl]porphyrin, was developed to modify interface between poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) and perovskite. The modified devices increased their highest power conversion efficiency (PCE) 14.05% relative 11.35% for reference...
Conversion of CO2 by hydrogenation into higher hydrocarbons has attracted much attention due to the continuous increasing concentration in atmosphere. Fe5C2 was used as active site and mixed with K-modified supports for synthesize value-added hydrocarbons.
