Actually, this depends on the move order used by Black.
The Catalan may not be necessary.
If you play the Semi-Slav via 1.d4 d5 2.c4 e6, then you must deal with the Catalan, and if 3.Nc3 Nf6, You must deal with 4.Bg5 (QGD - 4...c6 isn't very good here) and 4.cxd5 exd5 (Exchange QGD). If 3...c6 instead, you have the Triangle Defense and must deal with the Marshall Gambit (4.e4)
If you play the Semi-Slav via 1.d4 d5 2.c4 c6 (more popular amongst Semi-Slav, non-Triangle Defense, purists), then you just have the Exchange Slav to deal with (3.cxd5 cxd5). 1.d4 d5 2.c4 c6 3.g3 is no good as the advantage of the Catalan depends on Black locking in his Bishop behind the pawn chain. Black can still develop his Bishop to f5 or g4. White has nothing after 1.d4 d5 2.c4 c6 3.g3?!

Sometimes white plays poker : If 2..c6 then 3. Nbd2. , if 3...Nf6 then 4.Nf3. if 4...Bf5 then we have a Breyer Slav, if 4...e6 then g3 Catalan with love!
Most Semi-Slav books recommend the Slav Move order, and in lines where White doesn't play 3.Nf3 and 4.Nc3, recommends NOT playing the Semi-Slav. See David Vigorito's book as an example (there are others as well).
For example, after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3, 4...Bf5 is recommended here over 4...e6.
After 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3, he gives 4...e6 here because e3 has already been committed, a move Catalan players should only play when forced to. He'd rather play e2-e4 in 1 shot.
After 1.d4 d5 2.c4 c6 3.Nd2, I'm not 100% sure what he specifically recommended, but I know it wasn't an early e6 because using the Slav move order was to specifically avoid the Catalan, which Black can do. The closest thing White can force is a Fianchetto System against a Slav with the Bishop outside the pawn chain, which is useless for White. With the Knight already on d2, I'd wager he recommends either 4...Bf5 or 4...Bg4 (don't have the book on me right now) as the Knight is on d2, not c3, and so no problems with the d5-pawn getting attacked in conjunction with b7.
The Catalan Proper can be 100% avoided if Black wishes to.
thanks guys
Black wins a pawn if white plays like this:
Just a trap to know.

I'm sure the Catalan player does not mind having the diagonal completely free to his bishop pressure. When I play the Slav the bishop often goes on b7. If I was being super defensive and playing against a fianchettoed king, my bishop would go there. Explain to me how the bishop is better outside of that diagonal, I want to hear and learn if you can.
The Catalan isn't strong against the Slav, but it's for complicated reasons. Like the Tarrasch Defence, there's no easy way to analyze this opening. One point is that a reason to prefer 2.... e6 over 2. ...c6 is to keep open the option of playing c5 all in one go later. With the fianchettoed king bishop c5 looks highly unlikely anyway for black and the pawn is well placed on c6 building up resistance on that long diagonal.

*nods in agreement*
I am actually studying the semi-slav. Can someone give me suggestions of variations?
