3、oping of metal cations on morphology, activity, and visible light response of photocatalysts.Authors: Tokyo University of ScienceSource:Japan Science and Technology AgencySubject: ChemistryType: from Englishto ChineseTerms:EnglishChinesephotocatalyst催化剂Cr铭Ni锲Cu铜Rh铭Pb铅H2氢气O2氧气Laparticle size颗粒尺寸SrTiO

4、353 酸 钛photogeneratedelectrons光电子water splitting水分解Source language:A highly active photocatalyst NaTaO3:La for water splitting into H2 and O2 was successfully developed by the doping of La, Ca, Sr, and Ba into NaTaO3. The doping changed the morphology of the NaTaO3 particle. The decrease in the part

5、icle size and the formation of characteristic surface nanostep structure brought the excellent photoc atalytic performance. On the other hand, doping of Cr, Ni, Cu, Rh, and Pb was effecti ve for development of visible light responsive photocatalysts based on TiO2, SrTiO3, and ZnS with wide band gaps

6、. These doping photocatalysts showed activities for H2 o r O2 evolution from aqueous solutions containing of sacrificial reagents. Codoping of metal cations with high oxidation numbers such as Ta5+ and Sb5+ was effective for C r- and Rh-doped TiO2, and Cr- and Ni-doped SrTiO3. This effect of codopin

7、g was due to the charge compensation that contributed to suppression of formation of recombina tion sites between photogenerated electrons and holes. These doping photocatalysts th at show the activities for only half reactions of water splitting, that is H2 or O2 evoluti on in the presence of sacri

8、ficial reagents, can be used to construct Z-scheme photocata lysts for overall water splitting under visible light irradiation as demonstrated with Sr TiO3:Cr,Ta and SrTiO3:Rh photocatalysts.Target language:高活性催化剂NaTaO3光：水分解成氢气和氧气香格里拉研制成功由锢，钙，锹 掺杂，并NaTaO3光钢。催化剂改变了 NaTaO3光粒子形态。中的颗粒尺寸的减 小和特征表面nanostep

9、结构的形成所带来的光催化性能优良。另一方面，铭，锲， 铜，铭，铅掺杂了对可见光响应光催化剂的发展提供有效的基础上二氧化钛，钛酸锹，并与宽禁带的ZnSo这些掺杂光催化剂显示，氢气或氧气从祭祀活动演化 试剂含有水溶液。金属离子具有高氧化数，如 Ta5 + +和Sb5共掺杂了有效的铭 和Rh掺杂二氧化钛，铭和锲掺杂钛酸锹。这种共掺杂效应是由于电荷补偿促成 了光生电子和空穴之间的重组位点的形成抑制。这些掺杂催化剂的显示，只有一半的水分解反应，这是H2或O2试剂中的祭祀活动演化的存在，可以用来构建可见光照射下分解水的整体 Z型光催化剂的计划，与钛酸锹显示：铭，钥和SrTiO3:铭催化剂。Reading

11、plebuilding contractors and home owners want to save costs but reduce waste and emissions. Whether it s new construction, renovation or interior work, raw materials and products from chemical industry play a role in making buildings cheaper,safer -and, more environmentally friendly, andin future foo

12、ds and health products will have to be supplied to more and more people. Worldwide, they are doing their part: not only in the agricultural sector but also in human and animal nutrition as well as in the personal hygiene and pharmaceutical industry.Whether its cars, airplanes or ships - chemistry is

13、 making a decisive contribution to environmentally friendly mobility for the future. The products we develop range fromcatalytic converters, carbon gas filters, fuel additives and chemicals for a variety of energy saving applications. We are working to make these technologies affordable, powerful an

14、d safe. The most important is that climate change and energy supply might just be the biggest issues facing our planet, and there is an urgent need to reduce emissions and use energy more sustainable.Your comments:Chemistry plays indispensable roles in our daily life,which is the study of material p

15、roperties, composition, structure, change and the application of science. Since mankind began to explore chemistry, because the man had on chemical demand. It is closely related to our life, everywhere in our daily life. Agriculture, light and heavy, eat, wear, use, all cannot do without chemical. No chemical created ma
