Nanoscale Horizons (IF: pending)
1. Chemical induced fragmentation of MOFs for highly efficient Ni-based hydrogen evolution catalysts
Nanoscale Horiz., 2018, Advance Article
DOI: 10.1039/C7NH00193B
Most MOF-derived materials are obtained by thermal decomposition in an inert atmosphere and the mechanism of thermal decomposition has been rarely studied. In this new article, researchers from Peking University provide insights into the chemical-induced fragmentation mechanism of MOF decomposition and its promotion effect on catalytic performance. This might provide a new pathway for the synthesis and modification strategy of MOF-derived functional materials.
大多数MOF衍生材料都是在惰性气氛下热分解而获得，然而热分解机理的研究却很少。在本文中，北京大学的研究者对MOF分解的化学诱导断裂机理及其对催化性能的促进作用提出了新的见解，这一成果可能为MOF衍生功能材料的合成和修饰策略提供新的思路。

Chemical Science (IF: 8.668)
1. Encapsulation of ultrafine metal-oxide nanoparticles within mesopores for biomass-derived catalytic applications
Chem. Sci., 2018, Advance Article
DOI: 10.1039/C7SC04724J
Researchers in China and Spain have developed a strategy to encapsulate ultrafine metal-oxide nanoparticles (NPs) into KIT-6, a typical mesoporous silica. The method involves two steps consisting of the self-assembly of a MOF precursor in the silica mesopores, followed by a calcination process to transform the MOF into a metal-oxide NP. The NPs are confined and evenly distributed in the mesopores of the KIT-6 with a high metal loading of up to 13.6 wt %. These materials exhibit high catalytic performance compared to conventional supported Co-based catalysts.
中国华南理工大学和西班牙科尔多瓦大学的研究者开发了一种将超细金属氧化物纳米颗粒封装到典型介孔二氧化硅材料KIT-6中的新方法。该方法涉及两个步骤：首先在二氧化硅介孔中自组装MOF前体，随后经过煅烧将MOF转化成金属氧化物纳米颗粒。这些纳米颗粒被限制在KIT-6的介孔中并呈均匀分布，其金属负载量高达13.6 wt %。与常规的负载钴（Co）基催化剂相比，这种材料表现出了极高的催化性能。

2. β-NiS modified CdS nanowires for photocatalytic H2 evolution with exceptionally high efficiency
Chem. Sci., 2018, Advance Article
DOI: 10.1039/C7SC03928J
Scientists in Beijing have synthesized photocatalysts consisting of β-NiS modified CdS nanowires (NWs). The method uses CdS NWs as a template in the presence of sodium hypophosphite. A metal Ni intermediate is formed via an electroplating process that facilitates the growth of β-NiS nanostructures on the surface of CdS NWs. The NWs demonstrated a rate of hydrogen evolution of 793.6 µmol h-1 over a 5mg photocatalyst sample, almost 250-fold higher than that over pure CdS NWs. The apparent quantum yield reached a value of 74.1 % at 420 nm.
北京邮电大学和中国地质大学的研究者合成了一种由β-NiS修饰的CdS纳米线组成的光催化剂。该方法中，在次磷酸钠的存在下CdS纳米线被用做模板，通过电镀过程形成的金属镍（Ni）中间体能够促进纳米线表面上β-NiS纳米结构的生长。5 mg这种纳米线作为光催化剂样品时，析氢速率为793.6 μmol h-1，比纯CdS纳米线高近250倍。这种纳米线的表观量子效率在420 nm处可达到74.1％。
