Light can influence catalytic reactions in several ways: - Activation of Catalysts: Light can activate certain catalysts that are otherwise inert under dark conditions. For example, semiconductors like titanium dioxide (TiO2) become highly reactive when exposed to UV light. - Energy Input: Light provides the energy needed to overcome activation barriers, reducing the thermal energy required and enabling reactions at lower temperatures. - Selective Activation: Using light of specific wavelengths can selectively activate certain reaction pathways, enhancing product selectivity.
