Fig. 2: DOMM performance.
From: Pd nanocatalysts engineering for direct oxidation methane-to-methanol with 99.7% selectivity
a Catalytic performance of DOMM of c-Pd nanocrystals enclosed by the {100} facet and o-Pd nanocrystals enclosed by the {111} facet. b Catalytic performance normalized by surface atoms for both Pd nanocrystals with average sizes from 5 to 48 nm. c Recycling tests for o-Pd nanocrystals. d Catalytic performance with different reaction times for o-Pd nanocrystals (Color consistency is maintained between the top-left panel of Fig. 2d and its bar chart for DOMM product representation.). e Comparison of catalytic performance and CH3OH selectivity for CH4 direct conversion with various catalysts. All reaction conditions: 10 mL of water, 20.5 mg of catalyst, 70 °C, feed gas at 3.0 MPa with 1.1% H2/2.2% O2/67.2% CH4/20.57% Ar/8.93% He. Each reaction was tested two times to obtain the error bars.
