Innovation Solution
A metal-containing cluster catalyst comprising specific metals like gold, silver, copper, platinum, rhodium, palladium, nickel, cobalt, iron, manganese, chromium, and ruthium, which are used in a cluster form, either as simple substances, alloys, or metal oxides, to enhance catalytic activity and selectivity in carbon dioxide reduction reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional catalysts are used for carbon dioxide reduction, then the reaction can proceed, but the selectivity and reaction efficiency are insufficient
Solution Approach 1:
The patent applies parameter changes by utilizing metal clusters with specific oxidation states (0, +1, +2) and controlling the size and composition of the clusters to optimize both reaction efficiency and selectivity. The oxidation state and cluster size are key parameters that are systematically varied to achieve high-performance catalysis for carbon dioxide reduction.
Solution Approach 2:
The patent employs composite materials by combining metal clusters with carbon materials (such as carbon nanotubes, graphene, or carbon nanofibers) to create hybrid catalyst systems. This composite structure leverages the catalytic activity of metal clusters and the high surface area and conductivity of carbon materials, thereby improving both productivity and reliability simultaneously.
2Productivity
If metal clusters with specific oxidation states are used, then catalytic activity improves, but the complexity of catalyst design and synthesis increases
Solution Approach 1:
The patent applies segmentation by dividing the catalyst into distinct functional components: metal clusters with specific oxidation states embedded within or on the surface of carbon materials. This segmentation allows independent optimization of each component's properties while simplifying the overall design and synthesis process through modular assembly.
