Direct methane conversion with oxygen and CO over hydrophobic dB-ZSM-5 supported Rh single-atom catalyst

Isolated Rh atoms are supported on hydrophobic dB-ZSM-5. Single-atom Rh on dB-ZSM-5 is characterized with Ac-HAADF/STEM and CO adsorption FTIR. Direct conversion of methane to oxygenates is carried out in an autoclave in water charged with CH4, O2 and CO at 150 °C. Hydrophobic Rh-dB-ZSM-5 is compare...
