Enhancing electrochemical ammonia synthesis on palladium nanorods through surface hydrogenation

A Review on the Water‐Gas Shift Reaction over Nickel‐Based Catalysts

“…The demand for hydrogen is continuously growing as it is not only an important feedstock in chemical industries such as ammonia synthesis and methanol synthesis but also potential green energy to replace oil and natural gas. [1][2][3][4][5] For example, there has recently been increasing interest in utilizing hydrogen as a clean fuel in gas turbines or fuel cells. [6,7] Hydrogen is mainly produced by the steam reforming of fossil fuels, particularly methane, attributed to its high hydrogen-to-carbon ratio and wide availability.…”

Mesoporous Bimetallic Au@Rh Core–Shell Nanowires as Efficient Electrocatalysts for pH-Universal Hydrogen Evolution

“…Rhodium (Rh) has been investigated for many reactions due to its excellent catalytic performance. − However, it is not conducive to HER due to the strong binding force between the intermediate and the catalyst. , In order to enhance electrocatalytic performance, controlling the morphology and composition of Rh-based nanomaterials has attracted much attention. ,, At present, one-dimensional nanostructures have been reported for various electrocatalytic applications due to their high stability, high electron transport, and preferentially exposed active crystal planes. − Moreover, bimetallic core–shell structures have attracted considerable interest in the electrocatalytic field because they can alter the Fermi level of the metal to modify the adsorption strengths of intermediates and the elementary reaction rate on the surface . The unique properties of Au as a substrate enable the Au core@noble metal shell to show better catalytic performance in the catalytic process.…”

Two-Dimensional Heterojunction Electrocatalyst: Au-Bi2Te3 Nanosheets for Electrochemical Ammonia Synthesis

“…It is universally acknowledged that NH 3 is a basic organic chemical raw material for the manufacture of chemical fertilizers and the evolution of energy economy. − However, on account of the non-dipole moment and high inertness of nitrogen, the artificial fixation of nitrogen in NH 3 is still a huge challenge. − For example, the traditional Haber–Bosch process for NH 3 production has been developed for decades, but the use of pure N 2 and H 2 as starting materials under harsh reaction conditions limits its further advance. − Currently, a large amount of global energy (1–2%) is consumed and a huge amount of carbon dioxide is emitted by this process every year. , To alleviate these problems, exploring sustainable NH 3 production technologies is urgently needed. Electrochemical reduction of N 2 to NH 3 is a sustainable and green method of ammonia synthesis. , …”
