文章摘要：
As an emerging therapeutic gas, hydrogen (H2) is gifted with excellent biosafety, high tissue permeability, and radical-trapping capacity and is extensively considered as a highly promising antioxidant in clinics. However, a facile and effective strategy of H2 production for major inflammatory disease treatments is still lacking. In this study, by a facile wet-chemical exfoliation synthesis, a hydrogen-terminated silicon nanosheet (H-silicene) has been synthesized, which can favorably react with environmental water to generate H2 rapidly and continuously without any external energy input. Furthermore, theoretical calculations were employed to reveal the mechanism of enhanced H2 generation efficacy of H-silicene nanosheets. The as-synthesized H-silicene has been explored as a flexible hydrogen gas generator for efficient antioxidative stress application for the first time, which highlights a promising prospect of this two-dimensional H-silicene nanomaterial for acute inflammatory treatments by on-demand H2 production-enabled reactive oxygen species scavenging. This study provides a novel and efficient modality for nanomaterial-mediated H2 therapy.

作為一種新興的治療氣體，氫氣(H2)具有優(yōu)異的生物安全性、高組織滲透性和自由基捕獲能力，并被廣泛認(rèn)為是臨床上非常有前途的抗氧化劑。然而，H2主要炎癥疾病治療藥物的生產(chǎn)仍然缺乏。在本研究中，通過一種簡單的濕化學(xué)剝離合成法，合成了氫封端的硅納米片(H-硅烯),它可以很好地與環(huán)境水反應(yīng)生成H2無需任何外部能量輸入。此外，通過理論計算揭示了H增強的機理2H-硅烯納米片的生成效率。首次探索了合成的H-硅烯作為有效抗氧化應(yīng)激應(yīng)用的柔性氫氣發(fā)生器，這突出了這種二維H-硅烯納米材料通過按需H2生產(chǎn)性活性氧清除。這項研究為納米材料介導(dǎo)的氫原子轉(zhuǎn)移提供了一種新穎有效的方式2治療。
