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.

SAPO-11分子筛作为微孔沸石,通常粒径大,而粒径小的SAPO-11分子筛具有较短的孔道,更有利于分子的扩散使SAPO-11分子筛具有更高的催化活性,但存在稳定性较差的缺点,如何在水热法基础上进一步合成纳米多级孔SAPO-11分子筛极具挑战。在水热合成SAPO-11分子筛基础上,通过对前驱体凝胶进行老化处理制备纳米多级孔SAPO-11分子筛。其中,在80℃用搅拌老化制备的SAPO-11分子筛有最小晶体尺寸,通过SEM可知通过搅拌老化制备的S11-80℃-stirring分子筛呈现一种均匀纳米棒状结构,这些纳米棒的直径约500~700 nm,长度约2~4μm。通过N_(2)吸附-脱附曲线及孔径分布图可知经过老化处理的SAPO-11分子筛较传统SAPO-11都具有更大的比表面积,搅拌老化与静置老化制备的分子筛相比而言具有更大的微孔比表面积与孔体积。且通过NH_(3)-TPD对SAPO-11分子筛酸性性质进行表征,所有老化处理合成的SAPO-11分子筛酸量都有所下降。2-甲基萘(2-MN)主要来源于煤焦油,可用于制备2,6-二甲基萘(2,6-DMN),用于合成高端聚酯,为此将上述纳米多级孔SAPO-11分子筛用于催化2-甲基萘烷基化反应,结果表明使用老化处理制备的纳米多级孔SAPO-11分子筛有77.8%的2-MN初始转化率,20.4%的初始选择性,2,6-DMN、2,7-DMN的物质的量比为1.13,反应第4小时有最高2,6-DMN选择性39.9%,通过系列表征揭示了纳米多级孔SAPO-11分子筛择形催化催化机理。

Ammonia, primarily made with Haber-Bosch process developed in 1909 and winning two Nobel prizes, is a promising noncarbon fuel for preventing global warming of 1.5 °C above pre-industrial levels. However,the undesired characteristics of the process, including high carbon footprint, necessitate alternative ammonia synthesis methods, and among them is chemical looping ammonia production(CLAP) that uses nitrogen carrier materials and operates at atmospheric pressure with high product selectivity and energy efficiency. To date, neither a systematic review nor a perspective in nitrogen carriers and CLAP has been reported in the critical area. Thus, this work not only assesses the previous results of CLAP but also provides perspectives towards the future of CLAP. It classifies, characterizes, and holistically analyzes the fundamentally different CLAP pathways and discusses the ways of further improving the CLAP performance with the assistance of plasma technology and artificial intelligence(AI).
