Feb 12, 2017 at 21:16 comment added Wolfgang Well, there are at least three meaningful q-analogs of the Catalan Numbers, and you could ask the same question for each of them. See Johann Cigler's answer to an old question of mine: mathoverflow.net/questions/89996/…

Feb 9, 2017 at 0:27 comment added Pritam Majumder I have made a small edit: added the factor $q^n$ in the previous q-analog. Sorry for the typo before
Feb 9, 2017 at 0:17 comment added Pritam Majumder @VladimirDotsenko Oops, thanks for pointing it out. Actually I want to keep the RHS as it is. I hope I have fixed it.

Feb 8, 2017 at 20:35 comment added Vladimir Dotsenko Incidentally, I think that the RHS of your identity should be $\binom{2n}{n}_q-q\binom{2n}{n-1}_q$.
