Summary: Heavy metal pollution is a global environmental issue. In this study, a screen printed electrode modified with bismuth powder (Bi-SPE) was prepared for the detection of Cd2+. The Bi-SPE exhibited a linear detection range of 5-50 μg/L and a detection limit of 4.80 μg/L for Cd2+. Compared to the bare screen printed electrode, Bi-SPE showed better detection performance by providing more active sites for heavy metal ion predeposition. The advantage of Bi-SPE is its ability to detect heavy metal ions without the addition of bismuth ions in the solution, enabling in-situ detection. The prepared Bi-SPE holds great potential for the detection of heavy metal ions in real water samples.

Summary: In this study, the influence of crystal facet exposure on ion transport behavior and adsorption performance of LiFePO4 samples was investigated. It was found that despite having a smaller surface area, LFP (01 0) exhibited superior adsorption performance. Computational investigation revealed that the differences in adsorption energy and migration energy on different exposed facets led to different adsorption rates. These findings contribute to a better understanding of the interface interaction between Li+ and the adsorbent and facilitate the design of more efficient adsorbents.

Summary: By fabricating three kinds of adsorbent precursors Li4Ti5O12 (LTO) with different exposed planes, the internal mechanism that links the material structure and Li+ desorption performance is revealed. LTO with the 110 planes exhibited the highest Li+ desorption efficiency of 98%, and the corresponding desorption product H4Ti5O12 (HTO) with 110 is more likely to adsorb Li+ as it delivered adsorption capacity up to 37.58 mg g(-1). The structural analysis reveals that more 8a sites were exposed on the 110 planes of the material, and the density functional theory (DFT) results clarify that Li+ diffusion to the 8a sites is favored (0.40 eV).
