The mechanism of photocatalytic conversion CO2 and H2O over copper oxide promoted titania, Cu(I)/TiO2, was investigated by means in situ DRIFT spectroscopy combination with isotopically labeled 13CO2. In addition to small amounts 13CO, 12CO demonstrated be the primary product reaction 2115 cm−1 Cu(I)−CO signature, indicating that carbon residues on catalyst surface are involved reactions predominantly photocatalytically activated adsorbed water. This confirmed prolonged exposure light water...
Abstract Metal-organic frameworks (MOFs) containing d 0 metals such as NH 2 -MIL-125(Ti), -UiO-66(Zr) and -UiO-66(Hf) are among the most studied MOFs for photocatalytic applications. Despite structural similarities, we demonstrate that electronic properties of these markedly different. As revealed by quantum chemistry, EPR measurements transient absorption spectroscopy, highest occupied lowest unoccupied orbitals -MIL-125(Ti) promote a long lived ligand-to-metal charge transfer upon...
Operando infrared spectroscopy in combination with a kinetic study is used to elucidate the role of potassium on conversion carbon monoxide over K-promoted MoS2 catalysts. More specifically, initial break-in transient has been studied detail. Stabilization reaction intermediates, and effect promoter intrinsic properties are discussed. Adsorbed alkoxy species were found play an important intermediate syngas alcohol route, it was that stabilizes these species. Moreover, electronic change upon...
The dynamic catalytic site on Mo/HZSM-5 for methane dehydroaromatization is formed during the initial phases of reaction. Labelling experiments show that carbon from carbidic active incorporated into final products.
In order to capture and separate CO2 from the air or flue gas streams through nanoporous adsorbents, influence of humidity in these has be taken into account as it hampers process two main ways: (1) water preferentially binds adsorption sites lowers overall capacity, (2) causes hydrolytic degradation pore collapse porous framework. Here, we have used a water-stable polyimide covalent organic framework (COF) N2/CO2/H2O breakthrough studies assessed its performance under varying levels...

Abstract Colloids have a rich history of being used as ‘big atoms’ mimicking real atoms to study crystallization, gelation and the glass transition condensed matter. Emulating dynamics molecules, however, has remained elusive. Recent advances in colloid chemistry allow patchy particles be synthesized with accurate control over shape, functionality coordination number. Here, we show that colloidal alkanes, specifically cyclopentane, assembled from tetrameric by critical Casimir forces undergo...
Titanium-based metal-organic framework, NH2-MIL-125(Ti), has been widely investigated for photocatalytic applications but low activity in the hydrogen evolution reaction (HER). In this work, we show a one-step low-cost postmodification of NH2-MIL-125(Ti) via impregnation Co(NO3)2. The resulting Co@NH2-MIL-125(Ti) with embedded single-site CoII species, confirmed by XPS and XAS measurements, shows enhanced under visible light exposure. increased H2 production is likely triggered presence...
Bimetal-organic-framework (Bi-MOF) NH2-MIL-125(Ti/Cu)-derived nanocomposites are systematically investigated to elucidate the role of individual species TiO2, CuxO and porous carbon matrix in photocatalytic activity. Among studied samples, TiO2/CuxO/C nanocomposite derived from heat processing NH2-MIL-125(Ti/Cu) under Ar/H2O vapor demonstrates highest H2 evolution performance due formation a phasejunction between well-crystallized anatase/rutile TiO2 polymorph, optimized codoped...
Two novel gallium ALD precursors, LGaMe2 and LGa(NMe2)2 with L = amidinate, were prepared. The auxiliary ligand (methyl vs . amido) dictates the growth: while halted growth after 3 cycles, enabled Ga 2 O /Ga S deposition H O/H S.
The equilibrium adsorption of linear and branched C6 alkanes n-hexane, 2-methylpentane, 3-methylpentane 2,3-dimethylbutane on silicalite-1 has been investigated using a novel technique—the tapered element oscillating microbalance (TEOM). For small "kink " in the isotherm is observed at about 4 molecule (unit cell silicalite-1)−1. measured isotherms both 2-methylpentane 303 K for first time show second-step loadings over cell)−1. A two-step behavior confirmed single alkanes. This observation...
