DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The main objective of this study is to develop a photocatalyst with high activity for the photocatalytic reduction of carbon dioxide (CO2). The photocatalysts prepared include AgTaO3 (perovskite type catalyst) and titania, Both the photocatalysts were prepared by sol-gel method and were further loaded with Cu and Ni. On the other hand, loading CuO and NiO on self-made catalysts and commercial titania were prepared by impregnation method. The physical and photochemical properties of catalysts were characterized by XRD, UV-Vis, PL, SEM and TEM.
    The results of X-ray diffraction indicate that perovskite-type AgTaO3 has a good crystal phase at different calcination temperatures and different metal contents loaded by sol-gel method. UV-vis spectra show that the band gaps of AgTaO3 and TiO2 were 3.35 eV and 3.02 eV, respectively. In addition, AgTaO3 and TiO2 loaded with CuO by sol-gel method caused absorption edge extends to longer wavelengths and increased the light absorption in visible region. PL spectra indicate that adding metal to catalysts would cause defect and distortion, Existence of energy levels in gaps which could trap electrons and hence leaded to lower recombination of electrons and holes.
     Although some valuable results were obtained from the characterization of photocatalysts, and methanol was identified in the CO2 photocatalytic reduction and CO2 transforming into hydrocarbons was confirmed as well, however the conversion of CO2 was too low and reproducibility was not good enough. These facts might be due to improper installations and operation of the reactor system. Hence we could not compare the performance of various photocatalysts.
