<jats:title>Abstract</jats:title><jats:p>Activated carbon‐supported Mo‐Co‐K sulfide catalysts, prepared by stepwise impregnation, were used in the synthesis of higher alcohols via CO<jats:sub>2</jats:sub> hydrogenation. The catalysts with varying Mo contents and defined K/Mo and Co/Mo molar ratios exhibited relatively high CO<jats:sub>2</jats:sub> conversions and high selectivity to total alcohols and C<jats:sub>2+</jats:sub> alcohols. Moreover, the influence of calcination conditions on the sulfidation states and catalytic performance was studied. The surface sulfur runoff of the supported catalysts can be effectively suppressed by online calcination. As a result, the selectivity to total alcohols and C<jats:sub>2+</jats:sub> alcohols can be improved.</jats:p>
