Abstract
本发明涉及一种基于载体形貌调控的Ru‑W / ZrO2复合催化剂及其制备方法和应用。基于载体形貌调控的Ru‑W / ZrO2复合催化剂包括活性组分Ru、载体ZrO2和助剂W；载体ZrO2的形貌为棒状和 / 或球状；助剂W的存在形式包括非晶态WOx存在于载体ZrO2表面。本发明通过在不同形貌的载体ZrO2上负载活性组分Ru和助剂W，有利于在载体ZrO2表面形成高度分散的非晶态WOx物种，并构建出稳定的W‑O‑Zr界面结构，形成丰富的界面活性位点，增强界面电子耦合与促进界面电荷转移，进而调控活性组分Ru的电子结构，显著增强活性组分Ru与载体ZrO2之间的EMSI，从而显著提升催化活性、抗水性能和稳定性。
