Better than the original : A hybrid nanoparticle system consisting of peptide‐coated CdS and Pt nanoparticles acts as an enzyme mimic in the photoactivated reduction of nitrate (see picture). As compared to enzymes, the biotemplated nanoparticles exhibit enhanced activity, are optically activated, and can be used at elevated temperatures. Moreover, electron mediators and exogenous sacrificial electron donors are not needed.
