Hey everyone. I like to play queen pawn openings. Can anyone tell me which Grandmasters liked to play with 1.d4 more than other openings. I want to study their games. 

Alekhine!  He played a LOT of d4. 

You can find a nice database of his, and other d4 openings and players, here:

Anybody but Fischer and Tal? Lol.

Kramnik. He's been playing 1.Nf3 lately but he just plays d4 next turn.

Kasparov used it more than e4..
