A novel hybrid material with flower-mimicking morphology was fabricated with a facile coprecipitation method, and cytochrome P450 enzyme and cobalt phosphate were employed as organic and inorganic components, respectively. The hybrid nano-flowers showed excellent catalytic performance in the oxidative coupling of benzylamine, including the high conversion (99.9%) and selectivity (97.9%) in mild reaction conditions, as well as the satisfactory stability in the recycling experiments. Compared to free enzyme, the as-obtained materials exhibited enhanced activity. Such results indicate that the hybrid materials are potentially good candidates in the industrial enzyme catalysis.
