通过选择或修改构成MOF的有机和无机单元，可以控制其物理特性。MOF光催化剂的典型优选能带结构呈现出一个间隙，该间隙由有机配体的占据态和间位的空态构成。而对于含有Ti4+簇组成的MOF，因为它们呈现出一个空的d壳，以弥补导带最小值（CBM）。因此，人们对合成新的Ti基MOF的兴趣日益浓厚。迄今为止，只有极少数的一步合成可以生成（单金属）Ti基MOF。
有鉴于此，阿卜杜拉国王科技大学Jorge Gascon报道了一种新型坚固的钛基金属有机骨架ACM-1的一步合成和表征。要点1. 通过在干燥的二乙基甲酰胺（DEF）和氯苯的溶剂混合物中，通过异丙氧基钛，H4TBAPy和丙酸作为调节剂之间的一步反应，制备了名为ACM-1（用于高级催化材料的ACM）的新型Ti羧酸盐MOF。所得的多晶橙色粉末反复用DEF洗涤，并通过用乙醇（[TiO2(TBAPy)]·2C2H6O过滤来回收。
要点2. 基于无限的Ti-O链和H4TBAPy作为光敏剂配体，结合了高度移动的光生电子和在有机连接子处的强空穴定位，从而具有较长的电荷分离寿命。要点3. 带隙和CBM的合适能量为从析氢到有机底物的选择性氧化的广泛光催化反应提供了巨大潜力。Amandine Cadiau, et al, A new Titanium Metal Organic Framework with visible-light responsive photocatalytic activity, Angew. Chem. Int. Ed., 2020

Hello excellent website! Does running a blog like this require a large amount of work?
I have no expertise in coding but I was hoping to start my
own blog in the near future. Anyways, should you have any recommendations or techniques for new blog owners
please share. I know this is off subject however I simply wanted to
ask. Thank you!

Woah! I'm really digging the template/theme of this website.
It's simple, yet effective. A lot of times it's challenging to get
that "perfect balance" between user friendliness and visual appeal.
I must say you have done a superb job with this.
Additionally, the blog loads very fast for me on Safari.
Outstanding Blog!

Wonderful blog! I found it while browsing on Yahoo News.
Do you have any suggestions on how to get listed in Yahoo News?
I've been trying for a while but I never seem to get there!
Cheers

Today, while I was at work, my cousin stole my iphone and
tested to see if it can survive a 30 foot drop,
just so she can be a youtube sensation. My iPad is now destroyed and she
has 83 views. I know this is totally off topic
but I had to share it with someone!

Do you mind if I quote a couple of your articles as long as
I provide credit and sources back to your blog? My website is in the
very same niche as yours and my users would really benefit from some of the information you provide here.
Please let me know if this okay with you. Thank you!

Hi there just wanted to give you a quick heads up. The words in your post
seem to be running off the screen in Ie. I'm not sure if this is a
formatting issue or something to do with web browser compatibility but I figured I'd post
to let you know. The layout look great though!
Hope you get the issue resolved soon. Many thanks

Valuable info. Fortunate me I discovered your
site unintentionally, and I'm stunned why this
twist of fate didn't took place in advance!
I bookmarked it.
