【央视新闻】我国人工光合关键突破 二氧化碳与水在自然光下高效“变能源”
Yang Shi Xin Wen· 2026-02-02 03:28
记者从中国科学院地球环境研究所获悉,该所空气净化新技术团队受植物光合作用启发,提出了一种实现二氧化碳与水协同转化的通用策略。相关成果 1月31日在国际学术期刊《自然·通讯》发表。 植物通过光合作用,巧妙地将结构简单的二氧化碳和水转化为复杂的养分分子,为人类借助化学手段实现温室气体二氧化碳的资源化利用提供了自然范 例。然而,人工模拟光合作用的过程仍面临科学挑战,其关键瓶颈在于:光激发功能材料所产生的电子(用于还原二氧化碳)与空穴(用于氧化水)寿命极 短,难以实现二者反应的同步与持续进行。 我国科研团队这项新方案模拟植物暂存光生电子的生理机制,创新性地设计出一种电子存储路径,通过定向设计、制备材料结构,使其能够在光照时储 存电子,并在需要时精准释放,从而实现对二氧化碳与水反应速率和程度的精确调控。基于这一思路,研究团队成功构建出具有电子存储功能的银修饰三氧 化钨(Ag/WO3)材料。通过将其与催化活性组分酞菁钴复合进行验证,测得二氧化碳转化效率较纯酞菁钴提升了近百倍。此外,这一策略具备良好的通用 性与适用性,可根据实际需求构建多种结构适配的复合催化剂体系。该方案在自然光条件下运行稳定,为利用太阳能规模化转化二氧化 ...

握紧衔接2035远景目标的“关键一棒”|大江东:开局看上海④
Guo Ji Jin Rong Bao· 2026-01-29 00:04
刻度一:15.7%到19%,从"目的地"走向"全球枢纽" 转自:人民日报中央厨房-大江东工作室 开局看上海。去年底,上海市委八次全会审议通过"关于制定上海市国民经济和社会发展第十五个五年规划的建议",明确"十五五"将是上海"乘势而上的全 面发力期、转型升级的攻坚决胜期"。根据规划,到2035年,人均地区生产总值比2020年翻一番,基本建成具有世界影响力的社会主义现代化国际大都市。 当历史俯仰在过去与未来之时,沿着"十五五"划定的坚实坐标继续向前,以"五个中心"建设为核心使命锚定航向,以人民城市理念为温暖底色凝聚力量,打 造更完整的城市发展刻度。从每一个微小的刻度出发,握紧衔接2035远景目标的"关键一棒",上海的发展轨迹由此展开。 在上海建设"五个中心"的宏大命题中,有一项微小刻度,意味深长: 在2035年上海的航空发展目标中,国际航空旅客中转率,将从2024年的15.7%提升至接近19%。 业内人士分析,中转率的提升,意味着越来越多的人、航线和要素,把这里当作停留、转换、再出发的节点。城市角色随之变化,从目的地转向承载更高价 值的全球枢纽。 上海也是一座未来之城。迈克尔·尼尔森摄 尤其是人员流动。国际旅客中 ...
