Abstract The technology of steam reforming bioethanol has drawn great attention to green hydrogen production. However, catalyst deactivation always been a significant obstacle its applications. Here, series y Ni/Mo 2 TiC T x ( Ni/MTC) materials are tailored as robust catalysts for highly efficient long‐term ethanol reforming. results reveal that utilization efficiency up 95.6% and almost total conversion can be achieved at 550 °C using 10Ni/MTC‐72h catalyst. Moreover, this remarkable stability without obvious after 100 h reforming, which attributed the formation Ni─Mo alloy strong interaction Ni‐Mo m ‐Mo 2‐m structure. FTIR‐MS studies demonstrate superiority reinforcing low‐temperature activation, verified by faster acetate species than with Ni/Al O 3 . adsorption energies on surface Ni (−1.07 eV) Ni/MTC (−1.46 compared density functional theory calculations show activating during This study provides new implications stabilized construction, is expected substantially promote development application bioethanol‐to‐hydrogen production technologies.

Single Atom Environmental Catalysis: Influence of Supports and Coordination Environments

Advanced Functional Materials, Год журнала: 2023, Номер 33(50)

Опубликована: Авг. 27, 2023

Abstract Single‐atom catalysts (SACs) are desirable in environmental catalysis due to friendliness, structural stability, and maximum utilization of active metal sites. Extensive research has compared the catalytic performance between SACs with different single‐atom metals. However, their is also highly dependent on supports, which play an important role modulating local coordination environment SACs. Unfortunately, a comprehensive review that systematically discusses relationship supports environment, as well combined effects scare. In this review, three widely investigated applications including advanced oxidation processes (AOPs), mainly Fenton Fenton‐like reactions, nitrate reduction reaction (NO 3 RR) focused. By correlating characterization results, performances, computational environments reactivity examined detail, from origin pathways AOPs NO RR attempted reveal. Finally look forward for potential opportunities challenges on‐demand applications, provided.
