Emerging MXene-based electrocatalysts for efficient nitrate reduction to ammonia: recent advance, challenges, and prospects

Energy Materials, Journal Year: 2024, Volume and Issue: 4(5)

Published: June 4, 2024

Ammonia (NH3) plays an irreplaceable role in traditional agriculture and emerging renewable energy. Its preparation industry mainly relies on the energy-intensive Haber-Bosch process, which is associated with high energy consumption large CO2 emissions. Recently, nitrate reduction reaction (NO3-RR) driven by has received extensive attention. This can efficiently synthesize NH3 water as a hydrogen source NO3- nitrogen under mild conditions, conducive to reducing promoting carbon cycle. It well known that properties of electrocatalysts determine performance NO3-RR. As two-dimensional material, MXenes (transition metal carbides/nitrides/carbon nitrides) possess excellent electrical conductivity, specific surface area controllable functional groups, shows great application potential field Herein, this review summarized structure, synthesis strategies elucidate possibilities from foundation application. Then, latest research progress applying MXene-based NO3-RR was applicability different detection methods analyzed. Finally, present challenges future prospects were presented. aimed provide thoughtful insights into rational design for sustainable synthesis.

Abstract Exposing different facets on metal‐organic frameworks (MOFs) is highly desirable to enhance the performance for various applications, however, exploiting a concise and effective approach achieve facet‐controlled synthesis of MOFs remains challenging. Here, by modulating ratio metal precursors ligands, facet‐engineered iron‐based (Fe‐MOFs) exhibits enhanced catalytic activity Fenton reaction are explored, mechanism facet‐dependent revealed in detail. Fully exposed (101) (100) spindle‐shaped Fe‐MOFs enable rapid oxidation colorless o ‐phenylenediamine (OPD) colored products, thereby establishing dual‐mode platform detection hydrogen peroxide (H 2 O ) triacetone triperoxide (TATP). Thus, limit as low 2.06 n m achieved, robust selectivity against wide range common substances (>16 types) obtained, which further improved incorporating deep learning architecture with an SE‐VGG16 network model, enabling precise differentiation oxidizing agents from captured images. The present strategy expected will shine light both rational nanomaterials modulated morphologies exploitation high‐performance trace chemical sensors.
