甲酸作为一种安全、可再生和有前途的储氢材料，其应用受到了广泛的关注。然而，探索高效的非均相催化剂用于FA的选择性脱氢仍然是一个具有挑战性的课题。本文通过煅烧锆基金属有机骨架材料，合成了超四方纳米ZrO_2（晶粒尺寸可达150 nm）。由于PdAg@ZrO2/C材料具有独特的富电子结构和表面碱性，因此该催化剂具有优异的催化活性（在50 ℃下的转化率为9206 h（-1））。这些结果可能有助于设计有效的催化剂用于FA脱氢和扩展的应用四氧化锆多晶没有掺杂剂或减少晶粒尺寸。
The application of formic acid (FA) as a safe, renewable and promising hydrogen-storage material has received considerable attention. However, exploring efficient heterogeneous catalysts for selective dehydrogenation of FA remains a challenging topic. In this paper, a super nanoteragonal ZrO2(The crystallite size reached even 150 nm) is synthesized by calcining Zr-based metal-organic framework. Because the unique microstructures of the material which possess the electron-rich property and surface basicity, the resulting PdAg@ZrO2/C catalyst exhibits excellent activity (Turnover frequency 9206 h(-1) at 50 degrees C) for the decomposition of FA. These results may contribute to the design of efficient catalysts for dehydrogenation of FA and extended applications of tetragonal zirconia polycrysta without the dopants or reduction of the crystallite size.
