Protocol for ambient CO2 capture and conversion into HCOOH and NH4H2PO4

Summary CO 2 capture and utilization into liquid fuels and high-added-value chemicals has been regarded as an attractive strategy to mitigate excessive carbon emissions. Here, we present a protocol to capture and convert CO 2 into pure formic acid (HCOOH) solution and solid fertilizer (NH 4 H 2 PO 4 ). We describe steps for synthesis of an IRMOF3-derived carbon-supported PdAu heterogeneous catalyst (PdAu/CN-NH 2 ), which can efficiently catalyze (NH 4 ) 2 CO 3 -captured CO 2 into formate under ambient conditions. For complete details on the use and execution of this protocol, please refer to Jiang et al. (2023). 1
