As salam alaikum
There is no mention in the Qur'an of rewards for disbelievers. On the contrary in several verses it is said that their deeds will go to waste for their disbelief:
"Who turn away from his religion and dies as disbeliever: those are the ones whose deeds will go to waste in this world and the Hereafter" (2:217)
"Who disbelieves without faith, his deeds will go to waste and he will be in the Hereafter among the losers" (5:5)
"It is not for the disbelievers to keep the mosque of Allah in a flourishing state while they bear witness to their own disbelief . It is these whose deeds have all gone to waste on the Day of Resurrection" (9:17)
On the other hand, it is also true that "whosoever as done so much as an atom's weight of good will see it" (99:7). This, however, does not imply any reward: in fact a deed without faith does not call for retribution according to a Qur'anic perspective.
With prayers for your success.
