摘　　要：在寻求可再生能源供应及解决环境问题的迫切需求下,光电、光催化、电催化等领域中多种技术被开发以解决这一迫切问题。其中,光催化技术因其可将清洁太阳能转化为化学燃料的优越能力而备受关注。在层出不穷的光催化材料中,具有阳离子可替代性的钙钛矿氧化物(ABO_3)在电子信息、太阳能电池和光催化等领域具有极大的潜力。由于这类材料具有活性高、成本低、稳定性好、结构易调控等独特性能,钙钛矿氧化物光催化剂在水分解、二氧化碳还原转化、固氮等方面取得了广泛的应用。本文综述了光催化的结构与合成方法,重点介绍了光催化的应用,最后展望了光催化的未来发展前景。At present,more than 80%of the world’s energy demand is fulfilled by the burning of fossil fuels,which has caused the production of a large amount of greenhouse gases,leading to global warming and damage to the environment.The high consumption of fossil fuels every year causes the energy crisis to become increasingly serious.Finding a sustainable and pollution-free energy source is therefore essential.Among all forms of energy sources,solar energy is preferred because of its cleanliness and inexhaustible availability.The energy provided by one year of sunlight is more than 100 times the total energy in known fossil fuel reserves worldwide;however,the extent of solar energy currently used by mankind each year is minute;thus developments in solar energy are imperative.To address the urgent need for a renewable energy supply and to solve environmental problems,a variety of technologies in the field of photocatalysis have been developed.Photocatalytic technology has attracted significant attention because of its superior ability to convert clean solar energy into chemical fuels.Among the photocatalytic materials emerging in an endless stream,perovskite oxide,with the general formula of ABO3,has great potential in the fields of solar cells and photocatalysis as each site can be replaced by a variety of cations.Furthermore,owing to its unique properties such as high activity,robust stability,and facile structure adjustment,perovskite oxide photocatalysts have been widely used in water decomposition,carbon dioxide reduction and conversion,and nitrogen fixation.In terms of carbon dioxide reduction,oxide perovskites can achieve precise band gap and band edge tuning owing to its long charge diffusion length and flexibility in composition.For the development and utilization of solar energy in the environmental field,perovskite oxide and its derivatives(layered perovskite oxide)are used as photocatalysts for water decomposition and environmental remediation.In terms of nitrogen fixation,the conventional Haber-Bosh process
