Reduction of CO 2 to methanol using renewable hydrogen is a promising but challenging strategy for carbon capture and utilization.
Conversion of CO2 to value-added chemicals has been a long-standing objective, and direct hydrogenation lower olefins is highly desirable but still challenging. Herein, we report selective conversion through over ZnZrO/SAPO tandem catalyst fabricated with ZnO-ZrO2 solid solution Zn-modified SAPO-34 zeolite, which can achieve selectivity for as high 80–90% among hydrocarbon products. This realized on the basis dual functions catalyst: production SAPO zeolite. The thermodynamic kinetic...
Hydrogenation of CO2 to methanol utilizing the hydrogen from renewable energy sources offers a promising way reduce emissions through utilization as carbon source. However, it is challenge convert with high activity and selectivity. Herein, we report class metal-oxide solid-solution catalysts: MaZrOx (Ma = Cd, Ga), which show selectivity up 80% single pass conversion reaching 4.3%–12.4% under reaction conditions H2/CO2 3/1, 24 000 h–1, 5 MPa. Structural electronic characterizations combined...
The role of formate species for CO2 hydrogenation is still under debate. Although has been frequently observed and commonly proposed as the possible intermediate, there no definite evidence reaction methanol production. Here, formation conversion over ZnZrOx solid solution catalyst are investigated by in situ/operando diffuse reflectance infrared Fourier transform spectroscopy-mass spectroscopy (DRIFTS-MS) coupled with density functional theory (DFT) calculations. Spectroscopic results show...
The BaTiO 3 /MXene/PVDF-TrFE piezoelectric pressure sensor had a wide detection range and short response time, which showed great advantages potential in the application of human motion monitoring.
Understanding the synergy of Cu0 and Cu+ in hydrogenation reactions is indispensable for reasonably modulating product distributions improving catalyst design. Herein, we investigated dimethyl oxalate on CeZrOx-supported Cu with varying molar ratios nCu+/nCu0. A volcano-type correlation structure activity indicates that selectivity ethylene glycol strongly dependent nCu+/nCu0 ratio, arising from matching rates activation carbonyl group-included reactants H2 Cu0, respectively. The maximal...
Abstract Converting CO 2 to olefins is an ideal route achieve carbon neutrality. However, selective hydrogenation light olefins, especially single‐component olefin, while reducing CH 4 formation remains a great challenge. Herein, we developed ZnZrO x /SSZ‐13 tandem catalyst for the highly of olefins. This shows C = −C and propylene selectivity up 89.4 % 52 %, respectively, suppressed down there no obvious deactivation. It demonstrated that isolated moderate Brønsted acid sites (BAS) SSZ‐13...
Hydrogen production from the dehydrogenation of formic acid (FA) is promising. Most current catalysts for FA are effective only in presence bases or additives. We report here newly developed iridium complexes containing conjugated N,N'-diimine ligands water without addition A turnover frequency (TOF) 487 500 h(-1) with [Cp*Ir(L1)Cl]Cl (L1=2,2'-bi-2-imidazoline) at 90 °C and a number (TON) 2 400 000 situ prepared catalyst [IrCp*Cl2 ]2 2,2'-bi-1,4,5,6-tetrahydropyrimidine (L2) 80 were...
A new iridium catalyst bearing a dioxime derived ligand has been developed for aqueous formic acid (FA) dehydrogenation in the absence of any additives. These catalysts can work at high temperature or room with efficiency and stability.
An obvious difference was found in CO<sub>2</sub>hydrogenation to methanol on Pd nanoparticles (NPs) supported inside and outside of carbon nanotubes (CNTs).
CO2 hydrogenation to methanol has attracted much attention. The mechanism, the factors affecting selectivity, and rate-determining step of reaction have not been clearly concluded. Here, mechanism on Cu/ZnO/Al2O3, Pd/ZnO, ZnZrOx catalysts was studied by in situ infrared spectroscopy HCOOH temperature-programmed surface (HCOOH-TPSR) experiment. It is shown that HCOO* a feasible more stable is, higher selectivity accompanied with less CO produced via decomposition HCOO*. H2–D2 isotope exchange...
Mn was an important alloying element used in Al–Mg–Mn alloys. However, it had to be limited a low level (<1.0 wt %) avoid the formation of coarse intermetallics. In order take full advantage benefits Mn, research carried out investigate possibility increasing content by studying effect cooling rate on Fe- and Mn-rich intermetallics at different levels Fe. The results indicated that Al–5Mg–Mn alloy with Fe (<0.1 %), intermetallic Al6(Fe,Mn) small size amount. With content, increased,...
