Transition-metal catalysts can require complex ligands, which may add significantly to the overall costs. In addition, the removal of trace transition metals in pharmaceutical and other applications remains a challenge31,32,33,34. In contrast, transition-metal-free cross-coupling strategies can ...
At the same time, other researchers have combined doping and recombination of metals to enhance the photocatalytic activity of ZnO. Nuñez et al. [150] prepared Pt/ZnO co-catalysts and synthesized gallium modified co-catalysts by hydrothermal method. The addition of Ga changes the structure of ...
Design of Efficient Oxygen Reduction Reaction Catalysts with Single Transition Metal Atom on N-Doped Graphdiyne Here we present systematic theoretical and experimental investigations of various N-doped graphdiyne (NGDY) supported transition metals (TMs) to shed light ... M Zou,J Yang,X Yue - 《Jo...
Transition-metals, like Cu, Co, Ni, Mn and Fe, were doped into CeO2 microspheres. The combination of hierarchical structure and metal doping afford superior catalytic activities of the doped ceria microspheres, which could pave a new way to advanced non- precious metal based catalysts for CO ...
(Scheme 1). The VCP motif can act as either an activated cyclopropane ring to undergo [3 + x] cycloadditions or a homologue of 1,3-butadiene to participate in [5 + x] cycloadditions. 14 Most of these transformations are catalyzed by transition metals, and five- to eight-membered ...
In particular, the metal-rich catalysts are of great interest as they resemble the metals’ properties (e.g., good thermal conductivity, high thermal and chemical stability) [49]. In the metal-rich phosphides (𝑥:𝑦 ≥1)(x:y ≥1) the electrons do not fully surround the phosphorus ...
Some research groups argued that, although iron ion existed in OER catalysts (NiFe oxides/(oxy)hydroxides) in the form of +3 oxidation state, it still acted as the main active site of the catalytic reaction [58,118,119]. Bell et al. [120] probed the short-range structure at Fe and ...
Other zeolites having transition metals, such as nickel, precipitated therein are known isomerization catalysts. Catalysts in which the transition metal is precipitated from the framework positions in the zeolite may have different catalytic properties, including a tendency to rapidly degrade by metal plug...
Due to their capability to form complexes with different transition metals can act as catalysts for many different reactions [25-29]. The cross linking agents can also be derived from metal complexes with O−N− or –S ligands for example, the intra-coordination salt such as salicylates, ...
