摘      要：Catalytic conversion of CO_(2) to high-value products is a crucial method to achieve targets of carbon dioxide emissions peak and carbon ***,realizing a controllable product distribution in a single CO_(2) hydrogenation process is of great ***,we prepared the CuFe nanoalloy catalyst that directly transforms CO_(2) to alkanes using physical sputtering method in mild *** characteristic results show that the proximity between Cu and Fe is the crucial factor to tunable products among the different *** formation of unique coordination of FeCu4 nanoalloys from high-energy sputtering process provides close interaction between Cu and Fe,which is favorable to formation of low carbon paraffin,however,a distant proximity and weak interaction will increase the selectivity of olefins and *** work provides a general strategy for tuning target chemicals and enriches the viewpoints in CO_(2) hydrogenation.
