The use of inorganic semiconductor particles such as titanium dioxide (TiO₂) has received relatively less attention in organic chemistry, although semiconductor particles have been widely used as a single electron transfer photocatalyst in water-purification, air-cleaning, and self-cleaning. In recent years, the photocatalysis on semiconductor particles has become an active area of research even in organic chemistry, since the heterogeneous semiconductor photocatalysis leads to the unique redox organic reactions. In an early stage, the semiconductor photocatalysis was applied to the oxidation of organic molecules. Semiconductor particles have also the potential to induce the reductive chemical transformations in the absence of oxygen (O₂), by using the suitable sacrificial hole scavenger. In this review, we summarize the representative examples of the reductive and oxidative organic reactions using semiconductor particles and the recent applications to the stereoselective reactions.

无机半导体颗粒如二氧化钛（TiO ₂）的使用在有机化学中受到的关注相对较少，尽管半导体颗粒在水净化，空气清洁和自清洁中已被广泛用作单电子转移光催化剂。近年来，由于异质半导体光催化导致独特的氧化还原有机反应，因此即使在有机化学中，对半导体颗粒的光催化也已成为研究的活跃领域。在早期阶段，半导体光催化被用于有机分子的氧化。半导体颗粒还具有在不存在氧气（O ₂），使用合适的牺牲性空穴清除剂。在这篇综述中，我们总结了使用半导体颗粒的还原性和氧化性有机反应的代表性实例，以及对立体选择反应的最新应用。
