摘要
A manufacturing method of a solid copper-carbon catalyst includes the following steps: providing a copper precursor solution, performing a spraying step, performing a drying step, and performing a calcining step. The copper precursor solution includes a copper precursor, a carbon carrier and a first solvent. In the spraying step, the copper precursor solution is dispersed to form a plurality of copper precursor drops. In the drying step, the copper precursor drops are dried to form a plurality of copper precursor powders. In the calcining step, the copper precursor powders are calcined to form a plurality of solid copper-carbon catalysts.
