Ionic liquids (ILs) are proposed as potential “green” solvents with remarkable properties. Deep eutectic (DESs) a new type of ILs additional properties, such higher biodegradability and lower price. DESs absorbents for various gas separations, CO2/N2, CO2/H2/CO, H2S/CH4, N2O/N2. Due to their large number, the screening is crucial. Although high absorption capacities were screened using solubili...

Steam reforming of ethanol in the membrane reactor using the Pd77Ag23 membrane was evaluated in Ni/CeO2 and Co/CeO2 at atmospheric pressure. At 673 K, the H2 yield in the Pd77Ag23 membrane reactor over Co/CeO2 was found to be higher than that over Ni/CeO2, although the H2 yield over Ni/CeO2 exceeded that over Co/CeO2 at 773 K. This difference was owing to their reaction mechanism. At 773 K, the...

In his paper, On the separation of the plane by irreducible continua,*! W. A. Wilson obtains the following theorem. Let F be the union of two bounded continua Hi and H2 having these properties: Hi and H2 are irreducible about A+B; Hi-H2 = A+B where A and B are continua and 4̂ 5 = 0; Hi and H2 contain subcontinua Ci and C2 respectively such that a = Ci>C2A>*0, 0 = Ci-C2J3^0, d and C2 are irreduci...

We report the design of efficient multicomponent photocatalysts (MPs) for H2 production under visible light by using water-soluble ultrathin titanate nanodisks (TNDs) stabilized by tetraethylammonium cations (TEA(+)) as building blocks. The photocatalysts are designed in such a way to significantly enhance simultaneously the efficiency of the three main steps in the photocatalytic process i.e.,...

Porosity loss, also known as physical aging, in glassy polymers hampers their long term use in gas separations. Unprecedented interactions of porous aromatic frameworks (PAFs) with these polymers offer the potential to control and exploit physical aging for drastically enhanced separation efficiency. PAF-1 is used in the archetypal polymer of intrinsic microporosity (PIM), PIM-1, to achieve thr...

A fully atomistic simulation study is reported to provide mechanistic insight into the superior performance experimentally observed for a polymer membrane (Carta et al., Science, 2013, 339, 303-307). The membrane namely PIM-EA-TB is produced by a shape-persistent ladder polymer of intrinsic microporosity (PIM) with rigid bridged bicyclic ethanoanthracene (EA) and Tröger's base (TB). The simulat...

Highly permeable zeolite membranes are desirable for fast gas separation in the industry. Reducing membrane's thickness is deemed to be an optimal solution permeability improvement. Herein, we report synthesis route of thin SSZ-13 via conversion template-contained surface gels. The gel fully crystallized into crack-free assisted with dual templates N,N,N-trimethyl-1-adamantammonium hydroxide (T...

Through the use of ambient pressure X-ray photoelectron spectroscopy (APXPS) and a single-sided solid oxide electrochemical cell (SOC), we have studied the mechanism of electrocatalytic splitting of water (H2O + 2e(-) → H2 + O(2-)) and electro-oxidation of hydrogen (H2 + O(2-) → H2O + 2e(-)) at ∼700 °C in 0.5 Torr of H2/H2O on ceria (CeO2-x) electrodes. The experiments reveal a transient build-...

This article provides details of a study that investigates hydrogen (H2) separation, purification and transport behaviour ceramic ?-alumina membrane compares it with ?-alumina modified Boehmite sol.
