Membranes with high selectivity and permeance are needed to reduce energy consumption in hydrogen purification and pre-combustion CO <sub>2</sub> capture. Polybenzimidazole (PBI) is one of the leading membrane materials for this separation. In this study, we present superior novel supported PBI (poly(p-phenylene benzobisimidazole), PBDI)...

We report the preparation and electrocatalytic performance of silver-containing gas diffusion electrodes (GDEs) derived from a silver coordination polymer (Ag-CP). Layer-by-layer growth of the Ag-CP onto porous supports was applied to control Ag loading. Subsequent electro-decomposition of the Ag-CP resulted in highly selective and efficient...

The electrochemical reduction of CO<sub>2</sub> holds great promise for lowering the concentration of CO<sub>2</sub> in the Earth′s atmosphere. However, several challenges have hindered the commercialization of this technology, including energy efficiency, the solubility of CO<sub>2</sub> in the aqueous phase, and electrode stability. In this...

Increasing helium use in research and production processes necessitates separation techniques to secure sufficient supply of this noble gas. Energy-efficient helium production from natural gas is still a big challenge. Membrane gas separation technology could play an important role. Herein, a novel poly(p-phenylene benzobisimidazole) (PBDI)...

Mesoporous nitrogen-doped carbon nanoparticles with atomically dispersed iron sites (named mesoNC-Fe) are synthesized via high-temperature pyrolysis of an Fe containing ZIF-8 MOF. Hydrolysis of tetramethyl orthosilicate (TMOS) in the MOF framework prior to pyrolysis plays an essential role in maintaining a high surface area during the...

In this study, the role of the noble metals Pt and Rh (0.5 wt.%) for the selective reduction of NO into N<sub>2</sub> is evaluated by the transient TAP technique and in-situ spectroscopy using a commercial stable ceria support (denoted as CZ) and applying isotopically labelled <sup>15</sup>NO and <sup>18</sup>O<sub>2</sub>. The transient...

The preparation and the performance of mixed matrix membranes based on metal-organic polyhedra (MOPs) are reported. MOP fillers can be dispersed as discrete molecular units (average 9 nm in diameter) when low filler cargos are used. In spite of the low doping amount (1.6 wt %), a large performance enhancement in permeability, aging resistance...

A nitrogen-doped carbon was synthesized through the pyrolysis of the well-known metal-organic framework ZIF-8, followed by a subsequent acid treatment, and has been applied as a catalyst in the electrochemical reduction of carbon dioxide. The resulting electrode shows Faradaic efficiencies to carbon monoxide as high as ∼78%, with hydrogen...

The performance of mixed-matrix membranes (MMMs) based on Matrimid<sup>®</sup> and benzimidazole-linked polymers (BILPs) have been investigated for the separation CO<sub>2</sub>/N<sub>2</sub> and the dependency on the filler porosity. BILPs with two different porosities (BILP-101 and RT-BILP-101) were synthesized through controlling the...

The development of new membranes with high H<sub>2</sub> separation performance under industrially relevant conditions (high temperatures and pressures) is of primary importance. For instance, these membranes may facilitate the implementation of energy-efficient precombustion CO<sub>2</sub> capture or reduce energy intensity in other...

Temporal analysis of product (TAP) is used to investigate the effectiveness of CO, C<sub>3</sub>H<sub>6</sub>, and C<sub>3</sub>H<sub>8</sub> in the reduction of a La–Zr doped ceria catalyst and NO reduction into N<sub>2</sub> over this pre-reduced catalyst. Hydrocarbons are found to be substantially more effective in the reduction of this...
