Recycling spent LiNi1-x-yMnxCoyO2 cathodes to high-entropy NiCoMnAlFe-LDHs for controllable hydrogen generation via NaBH4 hydrolysis
The recycling and environmentally friendly application of toxic metal cations from spent lithium-ion batteries is a global environmental challenge. This study utilizes the high structural tolerance of layered double hydroxides (LDHs) to synthesize high-entropy NiCoMnAlFe-LDHs from spent LiNi1-x-yMnxCoyO2 cathodes and liquid wastes, achieving efficient recovery of toxic metal cations. The obtained high-entropy NiCoMnAlFe-LDHs demonstrated rapid photo-thermal conversion capability driven by infrared radiation, generating localized high temperature on the surface of catalyst and rapidly catalyzing the hydrolysis of NaBH4 solution for hydrogen evolution. The hydrogen evolution rate reaches 1.72 mol·h−1·g−1·W−1 driven by 1050 nm infrared laser irradiation. The hydrolysis reaction of NaBH4 ceases immediately upon turning off the light source, allowing for controllable hydrogen release from NaBH4 and effectively solve the scientific challenges for NaBH4 as hydrogen carrier. This study offers a new approach for the recycling of spent lithium battery and the green utilization of hazardous materials.
期刊介绍：
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
