Synthesis of methanol via CO hydrogenation is a very important reaction. In recent years, the InO based catalysts were proved to be a sort of promising catalysts to accelerate this reaction, which have aroused extensive attention. However, design of novel InO based catalysts that can efficiently produce methanol from CO hydrogenation at low temperature is still in great need. Herein we fabricated the InZrO nanosheets via a simple solvothermal method, which had peculiar surface structure and plenty of oxygen defects. The InZrO nanosheets displayed excellent low temperature catalytic performance in a slurry reactor. The methanol selectivity (90 %) and activity (1.4 mmol gh) were achieved at 180 °C, which are 2.3 and 1.6 times than that of the counterpart nanoparticles, respectively. Water as a clean and cheap reaction solvent played a crucial role, which participated in the kinetic process of the catalysis. The particular catalyst structure and the solvent effect of water accounting for the outstanding reaction results.

InZrOx纳米片的合成及其在CO2加氢制甲醇中的应用


CO加氢合成甲醇是一个非常重要的反应。近年来，InO基催化剂被证明是一种有前景的加速该反应的催化剂，引起了广泛的关注。然而，仍然非常需要设计能够在低温下通过CO加氢高效生产甲醇的新型In2O基催化剂。在此，我们通过简单的溶剂热方法制备了 InZrO 纳米片，该纳米片具有独特的表面结构和大量的氧缺陷。 InZrO纳米片在浆态反应器中表现出优异的低温催化性能。在 180 °C 下实现了甲醇选择性 (90%) 和活性 (1.4 mmol gh)，分别是对应纳米粒子的 2.3 和 1.6 倍。水作为一种清洁、廉价的反应溶剂在催化动力学过程中发挥着至关重要的作用。特殊的催化剂结构和水的溶剂效应导致了出色的反应结果。
