In this work, we present the synthesis of Ag doped TiO₂ materials. The products are characterized by powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption, and hydrogen adsorption. The Ag/TiO₂ materials exhibit 3.65 times higher in hydrogen adsorption capability compared with the non-doped TiO₂ materials thank to the existence of Ti³⁺ species, which are Kubas-type hydrogen adsorption centers, and the Ag nanoparticles which provide spillover effects. We believe that this is the first time that both Kubas-type adsorption and spillover are exploited in the design of novel hydrogen storage materials.

在这项工作中，我们介绍了Ag掺杂的TiO ₂材料的合成。产品的特征在于粉末X射线衍射，透射电子显微镜，X射线光电子能谱，氮吸附和氢吸附。与未掺杂的TiO ₂材料相比，Ag / TiO ₂材料的氢吸附能力是未掺杂的TiO ₂材料的3.65倍，这要归功于存在着作为Kubas型氢吸附中心的Ti ³⁺物种以及提供溢出效应的Ag纳米颗粒。 。我们认为这是在新型储氢材料设计中首次利用Kubas型吸附和溢出技术。
