High-temperature ionothermal synthesis has been proven effective in preparing environment-friendly carbon nitride （CN）-based photocatalysts in either triazine or heptazine form for CO2reduction reaction （CO2RR）.However,such a process is usually energy-intensive and suffers from partial carbonization that results in non-porous catalysts and degenerating their ***,we report the preparation of highly porous CN polymers (porous C6N7,C3N3,C4.5N5) through a low-temperature solvothermal polymerization of cyameluric chloride itself or cyanuric chloride itself,or both,*** such,it avoids unfavorable carbonization and allows for fine control of its chemical structure and significantly enlarged surface area (up to669 m2g-1).The pincer-like 2,2′-bipyridine sites of porous C6N7alter the photocatalytic CO2reduction pathways via stabilizing the*HCO intermediates,which promotes further hydrogenation to produce CH4in a high *** from the carbonization-free polymerization,high porosity,and*HCO intermediate activation,porous C6N7gave a superior CO2RR to CH4performance (17.18μmol g-1h-1) as well as high stability （5 successive cycles）,outperforming the bulk and state-of-the-art counterparts of *** opens an avenue for the rational construction of efficient porous CN-based photocatalytic systems,demonstrating their great potential in energy conversion reactions.

区别于以往西藏城市研究聚焦于历史上的西藏城镇,强调自然地理、农牧业经济和宗教对城镇发展的高度影响,文章以和平解放,尤其是改革开放以来西藏的城市发展为研究对象,讨论了社会主义现代化新西藏时期城镇发展取得的历史性成就。具体而言,自和平解放到20世纪80年代初,西藏城市发展受到地方建设的迫切需要和当时国家计划经济体制的深刻影响,使得县级城镇大规模兴起。改革开放后到中央第五次西藏工作座谈会召开,西藏城镇化仍处于初步阶段,全国支援西藏很大程度上推动了西藏城市的空间扩张和外部形态变化,使城市发展凸显援藏色彩。2010年后,随着西藏经济社会发展和农牧民生活水平的提升,西藏城镇化进程进入加速阶段,城市发展内生动力增强。此时城市规划推动了西藏城市大规模现代化,也使得现代意义上的城市功能得以具备,城市群初步形成,城市成为推动西藏城镇化和经济社会发展的重要动力。

2021年的中央一号文件中首次提出建立健全县域城乡融合的体制机制。2022年和2023年的中央一号文件中均提到了“县域城乡融合”的相关内容。由此可见“县域城乡融合”已成为新时代城镇化建设的重要突破口。福建晋江作为城乡融合较为典范的县域城市,自改革开放以来就“始终坚持党和政府的正确引导,始终坚持做大做强民营经济推动地方发展、始终秉持包容性增长理念、致力于打造多元社会治理的格局”,走出了县域城乡融合的晋江之路。在国家提出“推动县域城乡融合”的大背景下,晋江县域城乡融合的经验不仅能丰富理论探索,也能从实践上对其他城市产生一定的借鉴作用,助力更多的县域城市实现融合发展。

论文以抗战时期《大公报》《救亡日报》等报道以及《南侨回忆录》等记载为资料基础,分析了陈嘉庚在中共中央南方局及其领导下的桂林、香港地区等进步新闻力量帮助下,冲破蒋介石当局层层封锁,在媒体上公开曝光福建暴政,进而团结海外华侨力量广泛参与救乡运动,并最终取得成功的历史。研究显示,陈嘉庚回国慰劳考察,尤其是访问延安这一代表性事件后发起的救乡运动,是陈嘉庚政治转向的重要因素。论文认为救乡运动是影响陈嘉庚政治认同的关键事件,对其从认同于国民党转向认同于中国共产党具有直接影响。
