Non‐Destructive Hydrophobic Engineering of Inverse Catalysts for Methanol Synthesis from CO2
Advanced Science, EarlyView.In this study, we report a non‐destructive hydrophobic modification strategy for ZrO2/Cu catalyst through physical mixing with PDVB. The optimized ZrO2/Cu‐PDVB catalyst achieves a methanol space‐time yield of 920.10 mgCH3OH gcat−1 h−1 under mild conditions, outperforming the unmodified catalyst by 30 %.
