Product Details
Name:FeCu-N-C DAC
Product Overview
Dual-Atom Catalysts (DACs) is a catalyst with two metal atoms forming the active site. The concept was first derived from methane monooxygenases (MMOs) discovered in the 1970s. The synthesis method of diatomic catalysts mainly includes two bottom-up (Bottom-up) and top-down (Top-down) strategies. The bottom-up strategy uses a carrier with a dual-core metal center, including pyrolysis, dipping, atomic layer deposition and ion exchange; the top-down method relies on the input energy to disperse the originally aggregated metal, such as ball grinding and atomic capture.

Product characteristics
1) High catalytic activity and selectivity: because to its special surface structure and electronic structure, can more effectively promote the chemical reaction, improve the catalytic efficiency. During catalysis, bimatom catalysts are able to reduce unnecessary side reactions and improve the selectivity of the target product, resulting in a purer product.
2) Special catalytic surface and electronic structure: The special structure of the diatomic catalyst facilitates the interatomic interaction in the reaction, allowing the reaction to proceed efficiently under milder conditions. In bimatom catalysts, the interaction between two atoms can regulate the charge distribution of the catalyst and optimize the electronic structure, thus further improving the catalytic performance.
3) Highly controllable: The catalytic site and electronic structure of diatomic catalysts can be accurately designed to meet the needs of a specific reaction. By adjusting the composition and structure of bimatom catalysts, it can be optimized and improved for specific reactions to improve the catalytic efficiency and stability.
4) Low heat activity and heat resistance: Diatom catalysts have the ability to convert trace heat into effective chemical energy, producing only limited heat when changing the reaction conditions, thus allowing for a more efficient use of the chemical reaction conditions. The bimatom catalyst can stabilize the caloric state of the reaction, reduce the change of the reaction conditions, inhibit or inhibit the decomposition of the reaction, and ensure the stability and controllability of the reaction.
