Key Topics to Revise
1
Green Chemistry Fundamentals
- Green Chemistry is the use of chemistry for pollution prevention by environmentally conscious design of chemical products and processes
- Coined by Paul T. Anastas, known as the 'Father of Green Chemistry'
- Aims to maximize efficiency and minimize hazardous effects on human health and environment
2
Twelve Principles of Green Chemistry
- 1. Prevention of Waste: Zero Waste Technology (ZWT) - waste from one process becomes raw material for another
- 2. Atom Economy: Maximize incorporation of reactant atoms into final product
- 3. Less Hazardous Synthesis: Use safer reaction pathways (BHC instead of DDT)
3
Introduction to Nanochemistry
- Nanoscience: Study of phenomena and manipulation of materials at atomic, molecular scales where properties differ significantly from larger scales
- Nanotechnology: Design, characterization, production and application of structures by controlling shape and size at nanometer scale
- Nanomaterial: Material with structural components having at least one dimension in 1-100 nm range
4
Characteristic Features of Nanoparticles
- Color Change: Gold appears red at nanoscale instead of yellow (100 gold atoms in cube)
- High Surface-to-Volume Ratio: 1 m³ cube divided into 1 nm³ cubes increases surface area dramatically
- Enhanced Catalytic Activity: More surface area provides more reaction sites (Pd, Pt nanoparticles for hydrogenation)
