Ways to break up CO2

i know that plants take in CO2 and give off O2, i am wondering if there is anything that humans have developed thats small that could also break apart C02? if there is could we use it to lessen that amount of CO2 in our atmosphere, which we could benefit greatly from.

C + 2O  ->  CO2 + energy             (combustion, also mammals)

energy + CO2  ->  C + 2O             - you gotta get the energy from somewhere
