No, it is not correct. notify + clause However, we usually say: be notified of He was notified of the need to turn up early. be notified of + noun/noun phrase

Not sure what you're after princess (as usual hehehe), teh 'gerund' part of your question threw me a little. Do you want an example of "notify" with an "ing" ending? Or do you want "notify" in a noun format?? "The council wrote to me notifying me of their intent to close the library." "The council sent me written notification about the library closure."

Not correct. I'll notify him that I'm going to the office.

You would probably never hear this form. We don't know who is going to the office. You might use: "I'll notify him that I'm going to the office." "I notified him that I'm going to the office." "I notified him that I went to the office." Any of these three are correct, depending on when you notify him and when you go to the office.
