No. Op-amp outputs are always within the limits of their supply voltage, never higher. They can amplify a small DC signal, but only up to the limit of their supply.
It takes a DC-DC converter to create a higher voltage from a lower one.

I used an op amp to amplify a DC voltage. I was measuring current through a wire (by measuring voltage differential across it). The real value was between 0 and 40 mV. I adjusted op amp gain to be 200x. This gave me an output from 0 to 8V.

My solar garden light has a 1.2V battery but the DC to DC converter in it boosts the 1.2V to about 3.5VDC to light the colors changing LED. It does not have a DC amplifier.
My audio amplifier amplifies the tiny signal level from my MP3 player so that it can drive a speaker. It does not have a DC to DC converter.
