全球范围内的环境污染和破坏引起了人们对全新的环境友好的清洁化学技术和工艺的迫切需求，这是化学科学家在绿色化学领域面临的最重要的挑战。作为环境和谐催化剂的强有力竞争者是在室温下以清洁方式操作的光催化剂，而迫切需要将这种安全的光催化系统应用于净化污染水、分解令人讨厌的大气气味以及毒素、固定CO2以及在巨大的全球范围内分解NOx和氯氟烃。为了解决这些巨大的任务，必须建立不仅能够在紫外光下而且能够在最环保的能源阳光下有效和高效地运行的光催化系统。为此，我们正朝着积极的方向前进，如所述，各种实际应用已经在手边。本报告涉及1）在可见光和/或太阳束照射下有效工作的第二代氧化钛光催化剂的设计和开发的新方法，2）氧化钛光催化剂在日本的实际工业应用，日本绿色化学的最新进展。
Environmental pollution and destruction on a global scale have drawn attention to the vital need for totally new environmentally friendly, clean chemical technologies and processes, the most important challenge facing chemical scientists in the field of green chemistry. Strong contenders as environmentally harmonious catalysts are photocatalysts that operate at room temperature and in a clean manner, while applications of such safe photocatalytic systems are urgently desired for the purification of polluted water, the decomposition of offensive atmospheric odors as well as toxins, the fixation of CO2 and the decomposition of NOx and chlorofluorocarbons on a huge global scale. To address such enormous tasks, photocatalytic systems that are able to operate effectively and efficiently not only under UV light but also under the most environmentally ideal energy source, sunlight, must be established. To this end, we are moving in a positive direction with various practical applications already at hand, as is described.The present report involves 1) new approaches in the design and development of second-generation titanium oxide photocatalysts which can operate effectively under visible light and/or solar beam irradiation, 2) practical industrial applications of titanium oxide photocatalysts in Japan, and 3) recent advances in green chemistry in Japan.
