Which statement from following about nanomaterial is NOT correct?
- A As the particle size decreases the total surface area of particles increases
- B Nanomaterial based catalysts exhibit increased catalytic activities
- C Nanosized \(\mathrm{Cu}\) and \(\mathrm{Pd}\) clusters have very less hardness than bulk metal
- D Carbon nanotube can act as electrical conductor
Answer & Solution
Correct Answer
(C) Nanosized \(\mathrm{Cu}\) and \(\mathrm{Pd}\) clusters have very less hardness than bulk metal
Step-by-step Solution
Detailed explanation
Nanosized copper and palladium clusters with diameter in the size range of 5-7 nm can have hardness upto \(500 \%\) greater than bulk metal.
