We report an aerobic partial oxidation of isobutylene into isoprene, acetone, and para-xylene using a mesoporous Ni TiO_x catalytic material. In this work, two catalysts were found to synthesize two of these three valuable products with high selectivity, with p-xylene being synthesized with a selectivity of 46.0% and isoprene being synthesized with a selectivity of 64.7%, with overall conversions of isobutylene being 34.0% and 11.9% respectively. These reactions were done at relatively low temperatures (300 °C or below) and are conducted at flow rates of 10 sccm oxygen and isobutylene. The nickel titania catalysts were studied extensively using various characterization methodologies such as TEM, Raman, XRD, and XRF.

我们报告了使用介孔 Ni TiO _x催化材料将异丁烯有氧部分氧化成异戊二烯、丙酮和对二甲苯的过程。在这项工作中，发现两种催化剂以高选择性合成这三种有价值的产物中的两种，合成对二甲苯的选择性为 46.0%，合成的异戊二烯的选择性为 64.7%，异丁烯的总转化率为 34.0 % 和 11.9%。这些反应在相对较低的温度（300 °C 或更低）下进行，并以 10 sccm 氧气和异丁烯的流速进行。使用各种表征方法，如 TEM、拉曼、XRD 和 XRF，对镍二氧化钛催化剂进行了广泛的研究。
