The development of carbon materials with high electrochemical performance for next-generation energy device is emerging, especially N, S co-doped carbon materials have sparked intensive attention. However,the exploration of N, S co-doped carbon with well-defined active sites and hierarchical porous structures are still limited. In this study, we prepared a series of edge-enriched N, S co-doped carbon materials through pyrolysis of thiourea(TU) encapsulated in zeolitic imidazolate frameworks(TU@ZIF) composites,which delivered very good oxygen reduction reaction(ORR) performance in alkaline medium with onset potential of 0.94 V vs. reversible hydrogen electrode(RHE), good stability and methanol tolerance. Density functional theory(DFT) calculations suggested that carbon atoms adjacent to N and S are probable active sites for ORR intermediates in edge-enriched N, S co-doped carbon materials because higher electron density can enhance O_(2)adsorption, lower formation barriers of intermediates, improving the ORR performance comparing to intact N, S co-doped carbon materials. This study might provide a new pathway for improving ORR activity by the integration engineering of edge sites, and electronic structure of heteroatom doped carbon electrocatalysts.

国家公园可以保护自然生态资源,促进地区的可持续发展。亚洲国家公园的建设历经理念萌芽、建设繁荣和稳定发展三个阶段,并因各国的地理环境和文化资源而异。梳理典型国家的国家公园建设模式和特征,发现亚洲多数国家的国家公园建设是在殖民地政府的主导下开始建立的,各国建设国家公园主要基于环境保护、旅游经济、野生动物保护等的目的,政府都会指派相关部门来专门负责国家公园的管理,一般会采取政府、社区、企业相结合来完成日常运营工作。利益相关者共同参与、构建多类型的国家公园、自然保护与旅游娱乐并举、公园分区使用等是亚洲现有国家公园的有效举措,或能为我国建设国家公园提供有益启示。

以舟山海岸带为研究区域,结合采样数据和社会经济发展数据,构建以社会因子、经济因子和自然因子为3个维度因子的海岸带生态系统综合承载力评估的指标体系。并参照经济学中的AD-AS模型,改进成综合总供给-综合总需求模型(SAD-SAS模型),根据生态系统中总供给与总需求之间的平衡关系,来计算舟山海岸带综合承载力量值,并尝试将海岸带综合承载力值的分类标准在原来的基础上分为5类,最后评价其所处的承载力水平。研究结果表明:舟山海岸带综合承载力在2005—2008年时处于微幅上升的阶段,年均增速为6.5%,在2008—2009年开始出现稍微的下降,下降幅度为3%;SAD-SAS模型作为生态学与经济学交叉的模型,为海岸带综合承载力评价提供了一种新思路。

以2000—2019年全球科研工作者发表的南海主题研究论文为基础,借助Citespace进行知识群组识别和研究主题辨识,发掘南海研究的前沿问题,并探索其对"南海命运共同体"的启示。结果表明:相关科研论文数量逐年上升,以海洋地理学、地球科学、大气科学、环境科学等占比最多,并表现出多学科化、交叉化和综合化的特征;南海周边国家对研究的贡献最大,以中国学者为最多,但还未形成合作网络。文献多围绕地形构造、气候、水文、生物、矿产资源展开,季风、海洋生物、潮汐是持续的研究热点;2010年开始,南海研究由基础研究向应用研究转化,并由自然属性、宏观资源研究向探讨具体地区、单项资源转变。建议以研究前沿为纽带,开展国际论坛;以基础研究为基石,建设环南海知识网络;以应用研究为方向,与周边国家开展合作;以科研为桥梁,初步探索"南海命运共同体"。
