"cc"?

Do you mean "c"? A 700c tire is one where the tire's bead has a 622mm diameter. The "28" (and the other 2-digit numbers) refer to the inflated width of the tire, in millimeters.

A 28-47mm tube isn't thicker-walled than a 25-32mm tube, it's just a wider tube made for wider tires. Since your 28mm tire is within the spec of the 28-47mm tube you could probably make it work just fine, but personally I'd recommend erring on the small side; tubes that are well-matched or a little too small are easier to mount than tubes that are too big.

If you want to achieve puncture resistance through inner tubes, the course of action would be to get puncture-resistant tubes and put tubeless sealant into them. Note that this would add some weight to your wheels and probably slightly worsen rolling resistance.

Other options for reducing punctures:
1-Puncture-resistant tires.
2-Puncture-resistant tire insert.
3-Tubeless conversion.
4-Using extremely wide tires at moderately low PSI.
