301 Redirection, Serp still showing old domain

I 301 Redirected my domain1.com
to domain2.com

when I am searching "site:domain1.com"

I am still seeing my old domain BUT the tittle and snippet is of domain2.com (new site)

The rankings of domain1 are also gone I thought the rankings would transfer to domain2..

its been like 15-16 days. What should I do?

Also domain2.com is an expired domain.

Why did I redirected?
Because I was not able to get adsense approval on domain1

I used to receive 250-300 users perday, but now they are reduced to 80-85 in new domain.


Kindly help
