A catalyst that generally has high activity at room temperature can be activated even at low temperature. Catalysts having high activity only under mild conditions are immobilized on photothermal nanomaterials so that they have activity even under low temperature and extreme conditions. The invention is useful when a catalyst substrate unstable at room temperature is used or a catalytic product unstable at room temperature is produced. | 08-15-2013 |
