Case Study

Lithium Manganate Anchored on Mesoporous Ceria Photocatalyst for Photoreduction of Hg(II) Ions

Al-Hajji L A, et al. Ceramics International, 2024, 50(14), 25494-25502.

A photocatalyst with high visible light capture efficiency was successfully designed and prepared by anchoring lithium manganate nanoparticles (Li2MnO3 NPs) on a mesoporous ceria (CeO2) network. The obtained Li2MnO3/CeO2 nanocomposite can be used for photoreduction of Hg(II) ions under visible light irradiation and exhibits high stability and high efficiency.
Key properties of Li2MnO3/CeO2 nanocomposite
· The presence of Li2MnO3 and CeO2 in the nanocomposites, exhibiting monoclinic and cubic fluorite structures with particle sizes ranging from 10 to 20 nm.
· Compared to pristine CeO2 nanoparticles, the incorporation of Li2MnO3 and CeO2 NPs resulted in remarkable enhancement of photocatalytic activity. The optimal 9% Li2MnO3/CeO2 composite exhibited a remarkable 98% reduction ability for Hg(II) within 60 minutes. The rate constant of the 9% Li2MnO3/CeO2 photocatalyst was approximately 6.47 and 3.85 times higher than that of Li2MnO3 and CeO2 NPs, respectively.
· This superior performance can be attributed to the efficient separation of photocarriers facilitated by the S-scheme heterojunction, large surface area, and mesoporous structures of the Li2MnO3/CeO2 nanocomposites.
· Furthermore, the stability and efficiency of the Li2MnO3/CeO2 nanocomposites were demonstrated by consistent Hg(II) photoreduction performance over five successive experiments under similar conditions.

Application of Lithium Manganite Hydrate in High-Capacity and Ultrafast Lithium Storage

Jiang C, et al. Journal of Power Sources, 2019, 413, 441-448.

Layered spinel lithium manganate hydrate (LHMO-LS) was successfully synthesized via a one-step hydrothermal lithiation process, which has a hierarchical structure consisting of two-dimensional nanosheets. Subsequently, the electrochemical performance of LHMO-LS as a cathode material for lithium-ion batteries was studied. The results show that the LHMO-LS material combines diffusion-controlled and pseudocapacitive charge storage mechanisms, with high capacity output and high rate capability.
Synthesis procedure of LHMO-LS material
· The synthesis of lithium manganite hydrates with layered-spinel phases (referred to as LHMO-LS) was carried out using a straightforward hydrothermal method. Initially, 5 mmol of birnessite-type manganese oxides were combined with 60 mL of 0.06 M LiOH aqueous solution, and then transferred into a 100 mL Teflon-lined stainless steel autoclave.
· Subsequently, the hydrothermal reaction took place for 48 hours at 160°C in an oven. Finally, the resulting precipitate was filtered under vacuum, washed, and dried at 70°C for 10 hours.
· Additionally, by adjusting the concentration of the LiOH solution, control samples of lithium manganese oxide with a single hydrated layered phase (referred to as LHMO-L) containing 0.04 M LiOH and lithium manganese oxide with a single unhydrous spinel phase (LMO-S) containing 0.16 M LiOH were easily prepared.
