摘要

研究了电离辐射在 LAPONITE-XLG 纳米粘土水凝胶中诱导的反应，并使用 ns 脉冲辐射分解将其与碱性水溶液中的反应进行了比较。LAPONITE 的浓度不会影响 1 和 2 wt% 水凝胶中水合电子的衰减率。在 2 wt%的水凝胶中检测了吡啶对水合电子的清除作用，结果与水溶液中的反应一致。发现吡啶或吡啶鎓没有 "笼效应 "或吸附效应。这表明，在不发生溶质吸附的条件下，LAPONITE 表现为一种惰性材料。

Ionizing radiation induced reaction in nanoclay hydrogel

Reactions induced by ionizing radiation in LAPONITE-XLG nanoclay hydrogel were investigated and compared with those in alkaline aqueous solutions using ns-pulse radiolysis. The LAPONITE concentration did not affect the decay rate of hydrated electrons in 1 and 2 wt% hydrogel. The scavenging of hydrated electrons by pyridine was examined in 2 wt% hydrogel, and was consistent with the reaction in aqueous solution. The absence of a “cage-effect” or adsorption effect for pyridine or pyridinium was found. This suggests that LAPONITE behaves as an inert material on condition that solute adsorption does not occur.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
