与一些功能化反应的氮杂芳族化合物通过TiO 2（太阳能）催化剂的环境负担进行了比较，在热条件下相同的反应。两种方法，LCA（生命周期评估）和EATOS（环境评估工具，有机合成），都基于实验的详细分析，用于评估。对热处理过程进行了一致的评估，以提供更好的环境性能。光催化由于所需的大量过量试剂和溶剂的管理而不利。尽管如此，光催化方法的良好产率和简单性仍是有希望的（并得到第三次评估EcoScale的积极评价）。光催化合成的环保可行的预防措施进行了讨论。
The environmental burden associated with some functionalization reactions of nitrogen-heteroaromatics via TiO2(solar) photocatalysis is compared with the same reactions under thermal conditions. Two methods, LCA (Life Cycle Assessment) and EATOS (Environmental Assessment Tool for Organic Synthesis), both based on a detailed analysis of the experiments, are used for the assessment. The thermal processes are consistently evaluated to give a better environmental performance. Photocatalysis is disfavored by the required management of a large amount of excess reagent and solvent involved. Still the good yield and simplicity of the photocatalytic method are promising (and are positively evaluated by a third assessment, EcoScale). The precautions for making photocatalytic syntheses environmentally viable are discussed.
