1. A method comprising:
introducing a ferrate(VI)-based hydraulic fracturing fluid into a subterranean formation,
wherein the ferrate(VI)-based hydraulic fracturing fluid comprises ferrate(VI) oxidizing agent having the formula M2FeO4, where M is an alkali metal, and an aqueous carrier fluid;
reacting the ferrate(VI) oxidizing agent with a surface of the subterranean formation so as to increase a pore volume of pores therein; and
interacting the ferrate(VI) oxidizing agent with carbon dioxide (CO2), so as to sequester the CO2 with the ferrate(VI) oxidizing agent within the pores.
