XRD和XPS分析表明,HER催化位点主要来自金属Ni,而石墨碳包覆原位生长的氧化镍/镍核壳结构则是OER催化活性位点。相关成果以“Hierarchical Nickel-Carbon Structure Templated by Metal-Organic Frameworks for Efficient Overall Water Splitting”为题发表在Energy & Environmental Science上。 图1 NF Ni(BDC)前驱体和NF @...
大佬们，我想问下Ni-BDC在800℃，氮气中热解，BDC分解生成什么啊，我想算一下活性物质负载质量，大佬们...

10.(3)将步骤(2)所述ni-bdc材料加入水中,再加入co盐和表面活性剂,混合搅拌均匀,得到悬浊液a;将二甲基咪唑分散至水中,得到溶液b;然后将溶液b倒入悬浊液a中,室温搅拌反应,离心取沉淀物,洗涤,烘干,得到复合前驱体nico-bdc@zif-67材料; 11.(4)将步骤(3)所述nico-bdc@zif-67材料在惰性气氛下升温进行煅烧处理,...
Metal﹐rganic frameworks (MOFs) M2(BDC)2(DABCO), (M=Co, Ni, Cu and Zn, BDC= 1,4‐benzenedicarboxylic acid, and DABCO= 1,4ヾiazabicyclo[2.2.2]octane) have been prepared via a simple and effective strategy by the ball﹎illing method, with no use of a solvent at room temperature. ...
alterations were made to any of the substances; each was utilized precisely as provided. synthesis in this crystal structure and topography analysis xrd analyses were used to evaluate crystallite size, crystal lattice type, volume of a unit cell, d-spacing and space group of ni-bdc. fig. 2(...
在本工作中,作者首先通过溶剂热法合成S掺杂的ZIF-8,通过煅烧浸渍再煅烧的策略,制备了Ni-NSC催化剂。X射线衍射(XRD),球差校正的高角环形暗场像扫描透射电镜(AC-HAADF-STEM)证明了Ni是以原子形式分散的。 图1.(a)Ni-NSC的合成方案...
(Shete et al., 2018, Saitou, 2014) XRD peaks of NiCu-MOF containing (1 1 1) and (2 0 0) planes at 45.2, 46.7° and 50.3, 51° indicate that the Ni and Cu has a polycrystalline structure. Which confirmed the interaction of the bimetal centers. In addition, FTIR was used to ...
