Enhanced syngas production from CO2 photoreduction over CoPd alloy modified NiAl-LDH under visible light†
We reported the modification of a NiAl-layered double hydroxide (LDH) by loading well-dispersed CoPd alloys through a NaBH4 reduction method. The modified NiAl-LDH achieved 14.5-fold and 2.1-fold improvements of the H2 and CO evolution rates and an applicable ratio of H2/CO (nearly 1 : 1) under visible light (λ > 420 nm). This study revealed the potential of alloys to adjust the H2/CO ratio and enhance syngas production for LDHs for the first time.
