10223373BaratThis proposal covers initial experiments to prove out a new family of catalysts which will carry out the biologically-inspired selective partial oxidation of methane. Products are likely methanol, but potentially some alkane hydrocarbons may be formed from C-C coupling reactions. It is clear that partial oxidation to methanol is the most economical and logical reaction choice. One would desire a catalyst with more selectivity during the oxidation step. The PIs step through an analysis of the options: heterogeneous, homogeneous, biological, whole cell, and biomimetic, weighing the possibility for success. They are left with what they term the bio-inspired approach. By further analysis they arrive at the choice of perfluoroalkyl metal phthalocyanine (an analogue of porphyrin) as a very likely catalyst for improved selectivity and also the possibility of C-C coupling catalysis as well. Some supporting calculations are consistent. Note that what is desired is a low temperature and pressure operating regime.Broader Aspects:This is an EAGER proposal because no data exists to support or refute the contention. If the PIs were correct, this would be an exciting opportunity. Good performance at moderate conditions would allow for the recovery of stranded or waste methane as liquid chemicals/fuels, which are far easier to handle, transport and utilize. This also is a GHG reducing strategy. The experimental program involves catalyst synthesis (not necessarily easy) of catalysts with various perfluoroalkyl groups and various metal ions, and then evaluation in straightforward laboratory equipment. Plans are to use a mix of chemistry and chemical engineering students to carry out the work, including undergraduates. Under-represented students will be sought, and because the enrollment is predominantly non-white, this involvement is likely. This project will have appeal to a number of students, as it involves catalyst synthesis and seeks to solve an environmental problem.

10223373Barat该提案涵盖了初步实验，以证明一系列新的催化剂将进行受生物启发的甲烷选择性部分氧化。产品可能是甲醇，但 C-C 偶联反应可能会形成一些烷烃。显然，部分氧化为甲醇是最经济、最合理的反应选择。人们希望催化剂在氧化步骤中具有更高的选择性。 PI 逐步分析以下选项：异质、同质、生物、全细胞和仿生，权衡成功的可能性。他们留下了所谓的仿生方法。通过进一步分析，他们选择全氟烷基金属酞菁（卟啉的类似物）作为非常有可能提高选择性的催化剂，并且也有可能进行 C-C 偶联催化。一些支持计算是一致的。请注意，所需的是低温和低压操作制度。更广泛的方面：这是一个迫切的建议，因为没有数据支持或反驳这一论点。如果 PI 是正确的，这将是一个令人兴奋的机会。在温和条件下的良好性能将允许将滞留或废弃的甲烷回收为液体化学品/燃料，这更容易处理、运输和利用。这也是一项温室气体减排战略。实验计划涉及具有各种全氟烷基和各种金属离子的催化剂合成（不一定容易），然后在简单的实验室设备中进行评估。 计划将混合使用化学和化学工程专业的学生来开展这项工作，其中包括本科生。将寻求代表性不足的学生，并且由于入学的学生主要是非白人，因此这种参与是有可能的。该项目将吸引许多学生，因为它涉及催化剂合成并寻求解决环境问题。
