Photoconversion of anthropogenic CO2 into tunable syngas over industrial wastes derived metal-organic frameworks

Industrial wastes such as electroplating sludges and anthropogenic CO2, are misplaced resources whose utilization is severely hampered by their complex compositions or low concentration. Herein, on the basis of the specific binding characteristic of metal ions with small molecules, we demonstrate gradient-upcycling of solid wastes into different metal-organic frameworks (MOFs) for anthropogenic CO2-to-syngas photoconversion. In low-concentration...
