To alleviate the global warming by removing excess CO2 and converting them into value-added chemicals,(photo)electrochemical reduction has been recognized as a promising strategy.As the CO2 reduction reaction (CO2RR) is involved with multiple electrons and multiple products,plus the complexity of the surface chemical environment of the catalyst,it is extremely challenging to establish the structure/function relationship.Atomically precise metal nanoclusters (NCs),with crystallographically resolved structure,molecule-like characters and strong quantum confinement effects,have been emerging as a new type of catalyst for CO2RR,and more importantly,they can provide an ideal platform to unravel the comprehensive mechanistic insights and establish the structure/function relationship eventually.In this review,the recent advances regarding employing molecular metal NCs with well-defined structure including Au NCs,Au-based alloy NCs,Ag NCs,Cu NCs for CO2RR and relevant mechanistic studies are discussed,and the opportunities and challenges are proposed at the end for paving the development of CO2RR by using atomically precise metal NCs.

与传统二维信息化视图技术相比,BIM技术在EPC项目中能够更好体现其管理流程的流畅性、应用实施的便捷性以及沟通交流的高效性。将BIM技术应用于EPC项目,可以提高沟通与管理效率、辅助设计分析和展示、辅助工程量准确测算、施工过程优化与控制,可大幅度提高建筑工程的集成化程度,促进建筑业生产方式的转变,提高投资、设计、施工乃至整个工程生命周期的质量和效率,提升管理水平。
建筑作为人类城市文明建设过程中的标志性产物,对环境产生了重大影响,虽然既有建筑所使用的资源是难以再回收的,但建筑却可以在原建筑基础上改建使之能够再利用。文章探讨了德国国会大厦的重建——利用原有建筑与新材料与技术融合展示出历史价值;郑州二砂文创园通过对原工业厂区遗址合理保护、设计,促进新老建筑融合,激发城市片区活力。认为:保护再利用既有建筑,延续了城市历史,实现经济、社会、文化、环境效益的最大化,实现城市的可持续发展。
