Abstract We address the low selectivity problem faced by electrochemical nitrogen (N 2 ) reduction reaction (NRR) to ammonia (NH 3 exploiting Mars-van Krevelen (MvK) mechanism on two-dimensional (2D) Ti N nitride MXene. NRR technology is a viable alternative reducing energy and greenhouse gas emission footprint from NH production. Most catalysts operate using an associative or dissociative mechanism, during which competes with hydrogen evolution (HER), resulting in selectivity. The MvK...
Polymer brushes offer a wide array of applications in surface modification. While recent advances have made these chemistries more user-friendly, scientific questions about fundamental polymer properties often remain unanswered. For example, copolymer brush composition, chain end fidelity, and dispersity prohibitively challenging to characterize. This conundrum produces need for chemically precise pathways evaluate brushes. To this end, contribution describes the synthesis an...
Abstract Heterogeneous photocatalysis combines the benefits of light‐mediated chemistry with that a catalytic platform facilitates re‐use (often expensive) photocatalysts. This provides significant opportunities towards more economical, sustainable, safe, and user‐friendly chemical syntheses both small macromolecular compounds. contribution outlines recent developments in design heterogenous photocatalysts their use to mediate polymerizations. We outline four classes heterogeneous detail:...
This article describes the development of polymer brush-based heterogeneous photocatalysts for PET-RAFT polymerization in aqueous environments.
Understanding multi-component transport behavior through hydrated dense membranes is of interest for numerous applications. For the particular case photoelectrochemical CO2 reduction cells, it important to understand electrochemical products including mobile formate, acetate and ethanol in ion exchange as one role membrane these devices minimize permeation products. Anion (AEM) have been employed other they act facilitate common electrolytes (i.e., bicarbonates). However, carboxylates well,...
Ammonia is a promising carbon-free fuel, but current methods to produce ammonia are energy intensive. New thereby needed, with one method being electrochemical nitrogen reduction cells. Efficient cell operation requires robust catalysts also efficient membrane separators that permit the selective transport of ions while minimizing products across cell. Commercial membranes have an unknown morphology which makes designing improved cells challenging. To address this problem, we synthesized...
Understanding multi-component transport through polymer membranes is critical for separation applications such as water purification, energy devices, etc. Specifically CO2 reduction cells, where the products (alcohols and carboxylate salts), crossover of these species undesirable improving design ion exchange to prevent this behavior needed. Previously, it was observed that acetate increased in copermeation with alcohols cation consisting poly(ethylene glycol) diacrylate (PEGDA)...
