Microfluidic-based on-chip electrocatalytic microcell system and method for fabricating the same

A microfluidic-based on-chip electrocatalytic microcell system, comprising:

• a microfluidic chamber configured to introduce an electrolyte and a gaseous reactant through independent channels, wherein the microfluidic chamber comprises inlet ports and outlet ports for continuous flow of the electrolyte, and integrated electrodes positioned to enable electrocatalytic reactions;
• a gas-liquid mixing system with a mixing chamber configured to ensure homogeneous mixing of the gaseous reactant and the electrolyte, wherein the gas-liquid mixing system connect with the microfluidic chamber;
• a flow power system with at least one peristaltic pump connected to the microfluidic chamber to control the flow rate of the electrolyte within the microfluidic chamber;
• and
• a flow stabilization system with a flow-dampening chamber to mitigate flow fluctuations and maintain stable liquid delivery to the microfluidic chamber;
• wherein the microfluidic-based on-chip electrocatalytic microcell system is capable of optimizing diffusion-driven reactions, minimizing external interference, and facilitating reaction efficiency in carbon dioxide reduction reactions (CO2RR).
