As the world searches for new ways to harness nature’s natural resources to help us produce enough power, learning how to control and harness light as a source of energy is essential. Along with how it can be used to control the attributes and functions of advanced materials.
In the third bp-ICAM seminar for 2022, Professor Jain explained how his laboratory is looking into harnessing the power of light, experimenting with a new form of photocatalysis that employs concentrated light. He also covered how the technology relies on metal nanostructures that function as visible-light-harvesting antenna. Drawing a striking example from the conversion of CO2 to form C1–C3 hydrocarbons on gold nanoparticles under visible light.
Also discussed in the webinar was the use of concentrated light for: achieving important transformations using milder conditions; altering the inherent catalytic properties of a metal and modulating product selectivity; driving thermodynamically uphill reactions where free energy is harvested from light and stored in the form of energy-rich bonds; and boosting electroconversion.
