The following specific commercial reagents were used in this study: phenol (Aldrich), sodium persulfate (Merck), and hydrogen peroxide (35 % v/v, Biopack) .
A synthesized Ce-doped TiO 2 catalyst (E GAP = 2.80 eV, S BET = 27.68 m 2 g -1 ) was used. The catalyst was prepared by the sol-gel method, modifying the procedure reported by Choi et al. (2010) , with Ce(NO 3 ) 3 6H 2 O (Aldrich) as metal-ion precursor. The obtained xerogel was calcined at 600 °C in a programmable furnace to remove organic chemicals and to crystallize initial amorphous TiO 2 to anatase and rutile-phase TiO 2 . The calcination was precisely controlled at a ramp rate of 6 °C min -1 and target temperature of 600 °C for 1 h, under air, followed by natural cooling down. The Ce-doped TiO 2 was prepared to give a doping level of 0.1 nominal atomic percent (at.%). The prepared material will be referred to hereafter as 0.1Ce (referring to 0.1 Ce nominal atomic percent). A more detailed description of the catalyst synthesis and its characterizations has been previously reported (Martin et al. 2015) .

First, the PMMA solution (PMMA, 950 K A4, MicroChem Corp) was spin-coated onto one side of the graphene/Cu sample with a spin-coating rate of 1000 rpm for 60 s and dried for 3 mins on a hot plate at the temperature of 80 °C. Oxygen plasma was used to etch the graphene on the back side of sample. Subsequently, sodium persulfate (1 mol/L, Sigma-Aldrich) solution was used to etch Cu foil, and the PMMA/graphene film was floated on the surface of the solution. The PMMA/graphene film was washed with distilled water several times to remove the etchant residue. After the rinsing of the PMMA/graphene film with distilled water, the PMMA/graphene film was scooped out by a SiO2/Si substrate at room temperature and then was dried overnight to reduce the water trapped between graphene and substrates. Finally, the PMMA was removed by soaking the sample in the acetone bath and dried with compressed nitrogen gas.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
