摘要: The catalytic activities of methane combustion La–Cr–O catalysts prepared with and without polyacrylic acid as a template have been compared. polymer-templated catalyst had higher BET surface area, 12.3 m2 g−1, than that obtained from the conventional precipitation method, 2.9 g−1. results XRD SEM experiments suggested structural characteristics were almost similar. Surprisingly, areal rate over small area was ten times larger large area. However, site time yields (STY) based on oxygen adsorption capacity similar, independent preparation conditions.
