Highly Selective Conversion of CH₄ to High Value‐Added C₁ Oxygenates over Pd Loaded ZnTi‐LDH

The selective oxidation of methane to high value-added liquid oxygenated compounds under mild conditions is great significance promote the efficient utilization carbon source, but it also faces dilemma low activity and over-oxidation. Here, ZnTi-layered double hydroxides (LDH)-A200 photocatalysts with Pd loading are prepared achieve methane, O2 as an oxidant ambient condition. highest generation rate C1 products (methanol formaldehyde) reaches 4924.47 µmol g−1 h−1 a selectivity close 100% over 0.5Pd-ZnTi-LDH-A200, which 20 times higher than that bare ZnTi-LDH-A200. photochemical results show modified present much separation efficiency electron-hole pairs. In situ X–ray photoelectron spectroscopy indicates nanoparticles hole acceptor, beneficial charge in photocatalysis. Furthermore, electron spinresonance temperature–programmed–desorption analysis prove helpful adsorption oxygen on surface ZnTi-LDH-A200, promoting production reactive species activation methane. All these factors work together conversion CH4 oxygenates.
