The results revealed that 7 wt% La2O3-3wt% CeO2 modified OC displays the highest average H2 yields of 3.2 mol·H2 mol−1·C2H5OH with an 87% ethanol conversion during the first cycle and 2.7 mol·H2 mol−1·C2H5OH with an 88% ethanol conversion during the fifth cycle. The ...
The conversion of ethanol into acetaldehyde in good-to-high yields was observed in flow-through and batch-type reactors under optimal conditions: at T = 10–20 °C, pH = 6.9–7.1, [C2H5OH]:[H2O2] = 50:50 vol.%. According to the SEM images, the pore sizes of the p...
