1、丙烷作为一种三碳(C3)烷烃,被广泛用作燃料。尽管CO2电催化取得了近期进展,但直接从CO2生产C3+分子仍然具有挑战性,因为存在高反应势垒和与C1、C2及H2产品的竞争反应。
2、本研究报道了一种由1-乙基-3-甲基咪唑功能化的Mo3P(ImF-Mo3P)纳米粒子组成的催化系统,该系统涂覆有阴离子交换膜,能够在电解槽中以-395 mA cm^-2的电流密度和91%的法拉第效率在-0.8 V相对于可逆氢电极的条件下,将CO2转化为丙烷,且稳定性超过100小时。
3、通过表征和密度泛函理论(DFT)计算,我们认为咪唑功能化改善了Mo原子在表面的电催化性能,并通过增加碳基中间体在Mo位点上的吸附能量,有利于形成丙烷的反应路径。
研究结果表明,膜涂层在长期测试中对稳定咪唑功能化的Mo3P纳米粒子表面起着至关重要的作用。

Right before the ceremony, completed the final quiz of assessment, it is the hardest quiz I've taken during 4 semesters study. I was listening to the principal's speech while reflecting on my MA study. I 've dreamed countless times of how I could pass it to graduate in my 1st semester. Right now, I sit in the conference hall, waiting for the moment I get honored on the stage. Everything is like occurred yesterday. all semesters are stressed out, but the past weeks are unimaginable, i can not believe i have done so many things. What satisfies me is that I organized them very well. 10 papers in the portfolio, innovative materials development, the two midterm quizzes, the mathematical calculation issues, group term paper, paper presentation and final quiz. meanwhile, i completed tesol capstone, hpu capstone symposium, published my research paper, presentation at hawaii tesol conference, all the rehearsals, did two campus jobs, once worked at 6 am, supported 3 Spotlight events of visiting international students attending schools in Denmark, South Korea, and Japan. I can't believe it while I am typing all this stuff. Without all the HPU Tesol faculty, I could not reach my destination. With all their constant corrections, professional inspiration, encouragement, "du, you can, you can be me," i am not who i was 2 years ago. There is so much need to say, in a word, the two years studying experience I would never forget in the rest of life, the best way to return to them is to apply what I 've learned into a real life situation. just checked out the transcript before post, 3 A 4 A- 5 B+. Life is like this. I have suffered so much unfairness based on the fact that I was born and raised in mainland china, what is estimable is that I hold the righteous value and do never give in, but pursue till the last breath of my life. i think it might be one of my charming that distinguishes me from mainland chinese people today and an obvious merit that tesol faculty appreciate https://t.cn/8FoiQlv
CU Pass 考试后递交EC特殊情况申请政策更新
⚠️紧急通知‼️
近期,部分学校已经更新了考试政策,具体内容如下:
“如果您已参加考试,则视为“适合考试”(fit to sit),即认为您有能力进行学术活动。即使考试成绩不理想,提交特殊情况申请(EC)且通过,也【不会】再有无上限分数(uncapped mark resit)的补考机会。”
这意味着您需要提前做出决策:是直接选择推迟考试(defer),还是接受考试成绩。
⚠️⚠️⚠️请大家务必重视这一政策调整。我们预计,越来越多的院校将会采取类似的措施。因此,不要再有“既拿不定主意是否defer考试,又想即使参加考试发挥不佳也享受分数无上限补考机会”的可能性。
为了您的学业顺利,请务必认真考虑并提前做好选择。如果没有把握,请直接申请Defer. #英国留学挂科申诉##澳洲sc申请##cupass说申诉##cupass一日一叨#
