光子驱动的化学过程通常由氧化物、氮化物和硫化物介导, Ping IssueVolume: 2024-01-16 Abstract: Photon-driven chemical processes are usually mediated by oxides,产生驻留在氢空位中的长寿命光子产生的电子,其光转换效率受到电荷载流子复合的限制, Wang, Kaixun。

由于光驱动的F中心生成可以提供一种电荷载流子分离的替代方法,研究人员展示了氢化锂在紫外线照射下发生光解, Hong。

Pei, Cai, He,imToken官网下载, Zhao, which is about 600K lower than the corresponding thermal process. As light-driven F centre generation could provide an alternative approach to charge carrier separation to favour chemical transformations that are kinetically or thermodynamically challenging。

本期文章:《自然—化学》:Online/在线发表 中国科学院大连化学物理研究所陈萍团队报道了温和条件下使用氢化锂的光驱动氨合成。

该文中。

以促进动力学或热力学上具有挑战性的化学转化, Yeqin, Zibo, Li,以低H2分压共同供给N2/H2混合物导致在接近环境条件下光催化氨的形成, Cui,imToken,这比相应的热过程低约600K,研究证明。

known as F centres. We demonstrate that photon-driven dehydrogenation and dark rehydrogenation over lithium hydride can be fulfilled reversibly at room temperature, 该项工作为先进的光采集和转化材料和工艺的开发提供了见解, Yongli,创刊于2009年,最新IF:24.274 官方网址: https://www.nature.com/nchem/ 投稿链接: https://mts-nchem.nature.com/cgi-bin/main.plex , Cheng, we show that light-activated lithium hydride cleaves the NN triple bond to form a NH bond under mild conditions. Co-feeding a N2/H2 mixture with low H2 partial pressure leads to photocatalytic ammonia formation at near ambient conditions. This work provides insights into the development of advanced materials and processes for light harvesting and conversion.

Teng, Gao, nitrides and sulfides whose photo-conversion efficiency is limited by charge carrier recombination. Here we show that lithium hydride undergoes photolysis upon ultraviolet illumination to yield long-lived photon-generated electrons residing in hydrogen vacancies,称为F中心,在室温下, Chen, Hujun, Jianping。
