Al2O3 supported catalysts in which Cu-Ni or Cu-Zn is main composition were developed and used for methanol decomposition reaction to produce CO and H2 with excellent properties of low temperature activity, selectivity, resistibility of high temperature and durativity, and for ethanol decomposition...
As these chiral catalysts contain only achiral ligands, special strategies are required for their synthesis. In this protocol, we describe strategies for preparing two types of chiral-at-metal catalysts, namely the Λ- and Δ-enantiomers (left- and right-handed propellers, respectively) of the ...
In a word, the present synthetic approach is facile, scalable, and reproducible, which can be easily facilitated to prepare other types of noble metals/metal oxide composite systems. 展开 关键词: iron oxide Pt nanoparticle flake-like heterogeneous catalyst hydrogenation ...
The poymerization of acetylene with different types of catalysts was investigated. Most of them have been used for this purpose first time. These are new Re catalysts and new class sterically straitened catalysts. Use of different catalysts has permeated to regulate the ratio between the rate of...
This paper presents a review of the various types of catalysts that have been used in several research works to reduce the tars in the producer gas derived from the biomass gasification process. The catalysts are divided into two classes according to their production method: minerals and synthetic...
their surface layers and the oxygen reactants is very strong44,45, producing tightly bound oxygen atoms that can hardly participate in the epoxidation reaction. Regarding the iron porphyrin, by contrast, the interaction of O2with the embedded single Fe atom is too weak and only molecular ...
supported CaO catalysts are active for the transesterification reaction, and their catalytic performance can be influenced by a variety of factors, such as the types of carbon supports, the concentration of impregnated CaO, the heat-treated temperatures of the catalysts, and the reaction temperatures....
In this account article, we review our recent achievements and related works in the development of enantioselective carbon-carbon bond forming reactions using these axially chiral phosphoric acids and their analogues as chiral Bronsted acid catalysts. The contents are arranged according to the type of ...
Their catalytic transformation into value-added chemicals is a crucial target, because it would reduce our ties to fossil fuels and non-renewable resources. In this Review, we discuss the unique reactivity offered by actinide metal complexes with respect to s-, p- and d-block metals resulting ...
CO oxidation is an important primary reaction in automotive catalysis, and has been studied extensively since the 1970s because of its fundamental nature and technological relevance to emission control regulations. In this Review, we investigate the deve
