Abstract

Organic electromechanical synthesis is an eco-friendly and efficient method for material synthesis, effectively addressing the high energy consumption and pollution problems in the traditional chemical industry. By combining hydrogen production from water electrolysis with organic electromechanical synthesis, the reactive oxygen/hydrogen from water hydrolysis can be utilized to oxidize/reduce organic compounds, reducing energy consumption and producing valuable organic products. However, this strategy still faces challenges when implemented in the industry. This paper addresses major technical challenges in the field, providing new insights for future advancements. Firstly, when selecting anode reactions for hydrogen production, it is important to consider the value and market demand of the oxidation product to match the production scale. Secondly, the development of efficient electrocatalysts and electrodes is required to enhance the oxidation kinetics and mass transfer of organics at the current density levels of industrial hydrogen production (500–2000 mA cm−2). Thirdly, it is essential to improve the selectivity and Faraday efficiency of the anode target product to lower the cost of subsequent separation and purification. Fourthly, existing anion and oxygen ion exchange membranes lack corrosion resistance to organic matter, and new separator materials with high ion conductivity and stability are crucial for the electrolytic coupling system. Finally, when combining organic oxidation and water electrolysis, the complexity of product separation increases, and it is recommended to integrate distillation, extraction, membrane separation, and electrochemical reactions to improve process efficiency.

249. Ion-Exchanged Phosphomolybdic Acid Interfacial Modification Enhances the Electrochemical Performance of LiNi0.9Mn0.1O2

Abstract

With the Keggin structure PMo12O403–of phosphomolybdic acid (PMA) taken into account, the interfacial physicochemical property of PMA was adjusted through Li-ion exchange, and then Li-exchanged PMA was adopted to modify the cathode material LiNi0.9Mn0.1O2(NM91) via the solid-phase method, aiming at improving the rate performance and cycling stability of the cathode. The optimal ion-exchanged PMA (PMA-e2)-modified NM91 (named 91PMA-e2) shows an initial discharge capacity of 216.6 mAh g–1at 0.1 C and a capacity retention of 84.8% after 100 cycles (1 C and 2.8–4.5 V) as well as the best rate performance, which is superior to those of pristine NM91. With characterization by X-ray diffraction (XRD), X-ray photoelectron spectroscopy, high-resolution transmission electron microscope, in situXRD measurements, etc., it indicates that PMA-e2 modification can reduce the Li/Ni mixing degree but enlarge the thickness of the lithium layer (TLiO6) and facilitate Li+diffusion. The results suggest that the Keggin structure of PMA as well as the acidity property and priority adsorption toward water molecules are associated with the Li-ion exchange degree. In combination with the depth-profiling XPS measurement of the spent samples experienced in 300 cycles, it illustrates that spent 91PMA-e2 possesses higher amounts of LiF and Ni3+but a lower amount of LixPOyFz, which are due to the coating layer generated from the Keggin structure of PMA-e2. Such a Keggin structure has the capacity to trap trace amounts of water and inhibit the hydrolysis reaction of PF5, consequently maintaining the stable structure of the cathode and achieving superior cycling retention.
