The electrochemical reduction of CO2 from flue gas or direct air capture to relevant syngas mixtures is a promising route toward mitigation environmental pollution and production bulk chemicals fuels. Among the different cell types, gas-fed zero-gap electrolyzers are as energy-efficient scalable devices. We herein investigate influence operational parameters related cathode water management, such orientation, humidification, compression onto CO2R. By stepwise optimization our not yet fully...
In recent years, metal-rich sulfides of the pentlandite type (M9S8) have attracted considerable attention for energy storage applications. However, common synthetic routes towards pentlandites either involve intensive high temperature procedures or solvothermal methods with specialized precursors and non-sustainable organic solvents. Herein, we demonstrate that ball milling is a simple efficient method to synthesize nanosized bimetallic particles (Fe4.5Ni4.5S8, Pn) an average size ca. 250 nm...
In recent years, formic acid (FA) has garnered attention as a compelling molecule for various chemical and everyday applications Additionally, with studies demonstrating direct FA generation through CO2 electrolysis, it can serve stable liquid hydrogen carrier. Nevertheless, FA‐permeability via semi‐permeable ion‑exchange membranes (FA‐crossover) still constitutes major issue in scalable polymer‐electrolyte separated zero‐gap electrolyzers, limiting the breakthrough of technology to...

Abstract Carbon dioxide electroreduction (CO 2 R) is a promising technology for mitigating industrial CO emissions and generating valuable chemicals using renewable energy sources. Recent advances have centered on fine‐tuning catalyst materials their micro‐environments, stimulating interest within the R community. However, testing novel often occurs under conditions different from those relevant to applications. In this study, we explore transferability of results obtained Ag‐based gas...
Abstract Reducing the cost of PEM water electrolyzers is crucial for making green hydrogen economically viable achievable by cheaper catalysts as well bipolar plates. This study demonstrates first time use uncoated carbon plates (C‐BPs) an alternative to titanium (Ti‐BPs). The corrosion phenomena C‐BPs versus Ti‐BPs are investigated through ex situ and in accelerated stress tests. findings show that pH values, especially between 1 0, exponentially influence current density Ex tests revealed...
Electrochemically converting CO2 to renewable synthons is steadily becoming a globally scalable and important utilization technology. Nevertheless, most industrial endeavors employ catalysts based on metallic Ag or Au, with few catalytically competitive alternatives, showing similar activity, high mass cost efficiency. Similarly, this effort hindered by insufficient testing of promising materials in application-oriented conditions. We herein present holistic pathway starting from the...
Abstract Eine der größten Herausforderungen elektrochemischen Umwandlung von CO 2 zu in Zero‐Gap‐Elektrolyseuren ist die Skalierung dieser Systeme den industriellen Maßstab.

We recently described a new approach to surfactant-free latex dispersions prepared by emulsification of partially neutralized linear acrylic acid-containing styrene-acrylic copolymer without the use an organic solvent [Polym. Chem. 2017, 8, 2931–2941]. These secondary consisted polymer with molecular weight (Mn = 5000 g mol–1, D̵ 3) too low form useful coating. In work reported here, we built up and introduced partial gel content via reaction in dispersed state bisepoxide, followed...
Tailoring the properties of catalytic layer (CL) alongside its architecture is a key development towards ensuring both improve efficiency and selectivity for CO2 electrolyzers. Traditionally, CLs CO 2 R consist single binder-material or combination them overtaking ion-conductance maintenance hydrophobic environment. We herein decoupled these processes into two individual, stacked catalyst-containing layers. Specifically, was placed on GDL aiming to water management within CL during in...

Abstract Decreasing the catalytic loading and complexity of electrocatalysts for reduction CO 2 is a critical necessity towards globally generating carbon-negative synthons. This effort therefore calls development not only more active catalysts per employed g but also financially sound ones. Notably, molecular allow tuning electronic geometric environment around single-atom centers. Nevertheless, synthetic complexity, cost electrochemical instability still hamper their large-scale...
