The electrooxidation of propylene into propylene oxide under ambient conditions represents
an attractive approach toward propylene oxide. However, this process suffers from a low …

Creating and identifying catalytically active titanium sites is vital to further enhance
performance of titanium-containing zeolites, particularly for environmentally friendly titanium …

The concept of coordinatively unsaturated centers (CUCs) initially introduced in the realm of
homogeneous catalysis using organometallic complexes has demonstrated its …

Although Ziegler–Natta (ZN) catalysts play a major role in the polyolefin market, a true
understanding of their properties at the molecular level is still missing. In particular, there is a …

Although titanosilicalite-1 (TS-1) is among the most successful oxidation catalysts used in
industry, its active site structure is still debated. Recent efforts have mostly focused on …

The construction and determination of highly active Ti sites comprise one of the most
significant challenges in the rational design and synthesis of Ti-containing porous catalysts …

The crystallization process directly affects the physicochemical properties and active centers
of zeolites; however, controllable tuning of the zeolite crystallization process remains a …

Cu-exchanged zeolites are widely studied materials because of their importance in
industrial energetic and environmental processes. Cu redox speciation lies at the center of …

Metal-containing crystalline porous materials (CPMs) are gaining popularity in
heterogeneous catalysis because of their highly crystalline and porous systems, and their …

In this paper, which is the first part of a more extended work, we elucidate the molecular
