Abstract
The present disclosure relates to methods of combining chemical enhancement and physical enhancement to produce a combined synergistic total enhancement, and more specifically to methods of irradiating samples containing nanomaterials capable of producing chemical or physical enhancement to produce combined synergistic total enhancement.
Claims23
A method of enhancing a chemical reaction, the method comprising:
- a) providing a sample comprising:
- (1) a first population of nanomaterials comprising (i) an active metal surface, and
- (ii) a diameter in the range of 1 nm to 10 nm;
- (2) a second population of nanomaterials comprising a diameter in the range of 10 nm to 1,000 nm;
- (3) one or more chemical reactants;
- and,
- b) irradiating the sample with irradiation energy for a period of time sufficient for the one or more chemical reactants to undergo a chemical reaction to yield one or more products, wherein the irradiation energy is filtered, wherein the chemical reaction occurs at a reaction rate that is increased as compared to a corresponding control sample, and wherein the irradiation energy comprises X-rays.
