Nanoporous metallic nickel colloids (∼8.3 nm, see Figure) are produced by the thermal decomposition of nickel‐doped poly(vinyl alcohol) films. A small amount of carbon remaining on the surface protects the particles against further degradation. Adsorption isotherms indicate the colloids have both mesopores and micropores.
