Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

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〉

Global is facing energy and environmental crisis，many countries in the world are bound to develop alternative energy to displace petroleum fuels. Alternative energies can be more safe and clean to the environments such as hydrogen energy and fuel cell. The methanol fuel cell has been one of the alternative energy projects to due to its high energy conversion ratio and low pollution. But methanol fuel cell produces carbon monoxide during reaction process and deactivate the platinum catalyst in the methanol fuel cell. In the past few years, most of the catalysts with high porosity properties has been used in the methanol fuel cell. such as carbon block and carbon nanotubes. These carbonaceous materials have good electrical conductivity and high surface area. In recent years, many studies show that graphene have unigue structure, mechanical, physical and chemical properties. These excellent properties provide more active surface sites for a specific reaction.
The purpose of this study is to prepare a good support that to anchor platinum metal using as anode electrocatalyst material. The anode material will use graphene. First prepare graphene material. The Hummers method will be applied to make graphite oxide as a metallic precursor using dihydrogen hexachloroplatinate hexahydrate as the metallic precursor. To evaluate the performance of the methanol fuel cell with the function of metal concentration and to find the optimum reduction temperature for metal to disperse on graphene. Finally, rhodium can be used as second metallic to assistant catalyst. The metallic crystal phase can be determined by XRD, and particle size and dispersion of the metal can be observed by TEM. The catalyst has the tolenace toward CO resistance by changing redox current ratio and reaches the methanol fuel cell efficient can be determined by controlling Pt/Rh ratio particle size and dispersion.
