Model systems are very important to identify the working principles of real catalysts, and to
develop concepts that can be used in the design of new catalytic materials. In this review we …

Value-added chemicals, fuels, and pharmaceuticals synthesized by organic transformation
from raw materials via catalytic techniques have attracted enormous attention in the past few …

The design of cheap, non-toxic, and earth-abundant transition metal catalysts for selective
hydrogenation of alkynes remains a challenge in both industry and academia. Here, we …

Understanding the structural dynamics of a catalyst under reaction conditions is challenging
but crucial regarding catalyst design. Here, by a combination of in situ/operando …

Since the discovery that ceria is an active catalyst for selective hydrogenation of alkynes,
there has been much debate on the catalytic mechanism. In this work, we propose, based on …

Adsorption of molecules on active sites of heterogeneous catalysts significantly affects their
catalytic performance, which provides a perspective to understand the catalytic …

Catalytic CO 2 hydrogenation on metal oxides is attractive to realize carbon neutrality
initiatives. Understanding roles of oxygen vacancies of oxide-based catalysts is critical for …

Tuning surface oxygen vacancies is important for oxide catalysts. Doping elements with
different chemical valence states or different atomic radii into host oxides is a common …

The interaction of hydrogen with reduced ceria (CeO2− x) powders and CeO2− x (111) thin
films was studied using several characterization techniques including TEM, XRD, LEED …
