Manufacturing method of solid copper-carbon catalyst

A manufacturing method of a solid copper-carbon catalyst, comprising:

• providing a copper precursor solution comprising a copper precursor and a second solvent;
• providing a carbon carrier solution comprising a carbon carrier and a third solvent;
• performing a mixing-spraying step, wherein the copper precursor solution and the carbon carrier solution are contacted and mixed to form a mixed solution, and the mixed solution is dispersed to form a plurality of mixture drops;
• performing a drying step, wherein the plurality of mixture drops are dried to form a plurality of to-be-calcined powders;
• and
• performing a calcining step, the plurality of to-be-calcined powders are calcined to form a plurality of solid copper-carbon catalysts.

A manufacturing method of a solid copper-carbon catalyst, comprising:

• providing a copper precursor solution comprising a copper precursor, a carbon carrier and a fourth solvent;
• providing an organic ligand solution comprising an organic ligand and a fifth solvent;
• performing a mixing-spraying step, wherein the copper precursor solution and the organic ligand solution are contacted and mixed to form a mixed solution, and the mixed solution is dispersed to form a plurality of mixture drops;
• performing a drying step, wherein the plurality of mixture drops are dried to form a plurality of to-be-calcined powders;
• and
• performing a calcining step, wherein the plurality of to-be-calcined powders are calcined to form a plurality of solid copper-carbon catalysts.
