Methanol from Thin Air — The Nanochemistry of CO₂ Reuse

This video explores how nanochemistry turns CO2 from a greenhouse problem into a chemical resource — transforming carbon dioxide into fuels, plastics, and valuable chemicals using nanocatalysts, electrocatalysis, and smart materials. You will see how controlling matter on the 1–100 nm scale changes reactivity, selectivity, and energy efficiency in CO2 conversion, and why nanoparticles are at the heart of the emerging circular carbon economy. We compare different CO2-to-product pathways — methanol, polymers, synthetic fuels, formic acid, methane, and electrochemical products — and show how particle size, shape, composition, and support engineering tune what molecules you get out. The talk then looks at industrial challenges, frontier ideas like single-atom catalysts and AI-designed nanomaterials, and the long-term vision of turning carbon waste into wealth with green nanochemistry.

What this video covers:
What nanochemistry is and why nanoscale effects (surface area, quantum behavior) boost CO2 reactivity
How nanocatalysts adsorb and activate CO2 on high-area surfaces to break and remake chemical bonds
CO2 + H2 to methanol using Cu–ZnO nanoparticles and how this fits into a renewable “power-to-liquid” cycle
Converting CO2 into polycarbonates, polyurethanes, and other polymers as low-carbon plastics and materials
Using nanostructured catalysts in Fischer–Tropsch–type routes to make synthetic fuels from CO2 and hydrogen
Producing formic acid and methane (Sabatier reaction) as hydrogen carriers and synthetic natural gas
How catalyst size, crystal facets, alloying, and supports (oxides, carbon nanotubes) tune activity and selectivity
Electrochemical CO2 reduction on copper nanoparticles to CO, formate, methane, ethylene, or ethanol using electricity
Key engineering bottlenecks: catalyst degradation, energy efficiency, CO2 capture, and large-scale nanoparticle production
Frontier approaches: single-atom catalysts, bimetallic and core–shell nanostructures, AI-guided catalyst discovery
Economic and climate implications of large-scale CO2 utilization integrated with renewables and carbon policy
