This study presents a dual-regulation strategy combining catalyst modification and electrolyte engineering to promote CO₂ electroreduction toward multi-carbon (C₂₊) products. We synthesized Ag-doped CuO (Ag-CuO) catalysts and systematically evaluated their performance in KHCO₃ electrolytes containing various halide anions using a three-electrode H-cell configuration. The experimental design investigates the synergistic effects of applied potential, Ag doping concentration, and halide species/concentration on catalytic performance. This interdisciplinary experiment integrates fundamental concepts and techniques from inorganic, physical, and analytical chemistry. Beyond reinforcing core chemical principles, it cultivates essential competencies including scientific reasoning, research innovation, and self-directed learning-attributes crucial for chemistry education in the contemporary research landscape.
