The formation of urea by electrocatalytic reduction C1-reactants and NO3 - is an attractive way to store renewable electricity, close the carbon cycle, eliminate nitrate contaminants from wastewater. Involving insufficient supply C1 reactants multiple electron transfers makes reaction difficult achieve high Faraday efficiency yield at current density. Here, a synthesis approach presented via reductive coupling between liquid HCOOH on copper foam (CF) loaded Cu4Pt catalyst with optimized ratios. A 40.08 mg h-1 cm-2 achieved FE up 58.1% density -502.3 mA cm-2, superior productivity previously reported catalysts. No degradation observed over 120-h continuous operation such rate. highly efficient activity Cu4Pt/CF can be attributed synergetic effect Pt Cu sites tandem catalysis, in which doped enrich reactants, promote intermolecular dehydration, form adsorb large amounts *CO key intermediates. generate quantities intermediate *NH2. adsorbed intermediates *NH2 are basis for subsequent thermodynamic spontaneous C─N coupling.

Polymers of Intrinsic Microporosity Containing [2.2]Paracyclophane Moieties: Synthesis and Gas Sorption Properties

Advanced Functional Materials, Год журнала: 2024, Номер 34(47)

Опубликована: Май 25, 2024

Abstract The unique structure of [2.2]paracyclophane (PCP) with its rigidity, stability, and planar chirality has gained significant attention in polymer material research. In this work, the incorporation amino‐functionalized PCPs within polymers intrinsic microporosity (PIMs) is reported for first time. Three different PCP‐PIMs were prepared via a Tröger's base formation mechanism, their structures characterized solid‐state NMR, MALDI‐TOF, SEM. Their porosity was evaluated using gas adsorption (N 2 CO ) based on theoretical calculations such as Brunauer–Emmett–Teller (BET), NLDFT pore size distribution (PSD) ideal IAST /N selectivity (15/85), crucial separation when considering capture from flue gas. surface areas found to be between 200–230 m g −1 while ranged 46 70.
